I've not tested it, but something like:$gunzip_result=system("gunzip $gzfile 2>/dev/null");

So, OK, the job runs in cron: it fetches compressed files and processes them. If the files are corrupted, it deletes them. Sometimes they are bad on the remote server, in which case they will be downloaded and deleted each time.My cron logs extensively to STDOUT (directed to logfile in .crontab), using STDERR only for things that cause the script to stop: Ilikegetting emails from cron when bad stuff happens; it's just that corrupted files should not be on this list.I need the output from 'gunzip' to tell me if the file is corrupted. However, I am tired of getting emails from cron every time it encounters a bad file. How do I call 'gunzip' so that errors will not trigger emails from cron, while still letting the script that calls 'gunzip' know that it failed?This is probably a pretty easy one, but I'm pretty new to this cron stuff.Important PS: 'gunzip' is called from a Perl script, using$gunzip_result=system("gunzip $gzfile");
if($gunzip_result){
print,"$gzfile is bad: deleting...\n";
unlink $gzfile;
};

not triggering for every 5 minutes when I pushed the feature branch and raise a PRIt does not trigger for a feature branch because the documentation clearly states this:Scheduled workflows run on the latest commit on the default or base branch. The shortest interval you can run scheduled workflows is once every 5 minutes.This part should for sure trigger for a push to themainbranch though:push:
branches:
- mainand that might be redundant with the whole cron schedule. I'm not sure if a scheduled workflow will trigger for commits that have already been verified on push.Pull request against themainbranch should also automatically trigger without the whole cron part:pull_request:
types: [opened, synchronize, reopened]
branches:
- mainIf none of these trigger, first make sure your default branch really ismainand and notmaster.mainis the new default at GH, but your local git installation might still usemaster.See the documentation for more:https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#schedule

As a simple variant, use a watchdog. The program on regular intervals writes to a well-specified file. If the file haven't been updated in a long enough time, the program is unresponsive, and you should kill and restart it.With that said, the best solution is of course to fix the problems that cause the crashes or unresponsiveness. You should have enough logging to be able to pinpoint exactly when and where things go wrong. And perhaps make sure there's a coredump available for crashes, so you can debug it.

We have a remote device that is controlled by a C program. This program often fails so we want to introduce some monitoring. Either the program crashes and exits or some bug happens and the program is not responding.We want to set up a cron task or some other scripts for monitoring. What is the best modern practice for communication between C program and bash script or cron? We have access to the source code of this C program, so we can introduce some sort of error messages / events. Should they be written to a file that is later parsed by cron or some other monitoring script - or is this approach obsolete and there is some API or Linux messaging system for communication is such cases?

There is a bug where kubernetes dashboard is using API version batchV1beta1 for cronjobs which has been removed in kuberentes version 1.25.I've created a fixed version based on kuberentes dashboard version v2.7.0. I've published it on docker hub:beffe/kubernetes-dashboard:v2.7.0-fix-cj-2You can find the code changes here:https://github.com/kubernetes/dashboard/compare/master...beffe123:kubernetes-dashboard:v2.7.0-fixes

I have a kubernetes v1.25 and i cant show the details of my cronjobs anymore on all of my namespace of my kubernetes dashboard.
FYI, it works in command kubectl line i can list my cronjobs and access.
Dashboard version used 2.7.0On my project i modified the api version to the one recommended :
apiVersion: 'batch/v1'
kind: 'CronJob'When i check the logs of my kubernetes dashboard pod, i can see that every time i try to check the details of my cronjob on a namespace through graphical dashboard, an error log pop "There was an error during transformation to sidecar selector: Resource "cronjob" is not a native sidecar resource type or is not supported".Do you have any idea ?
Thank you

I suggest to usesed:myscript 2>&1 | ts | sed '$a\' >> cron.logThis adds\nat the end of the file only if it doesn’t already end with a newline.--l0b0

I'm trying to log both stdout and stderr from my cron task to a custom log file. If there is no output or error, I do not want to log anything. If there is either output or error, I want to log it to a new line and prefix it with the current timestamp.I've tried the followingmyscript 2>&1 | echo "$(cat -)" | ts >> cron.logThis gets me almost what I want. It will log both output and errors from myscript, prefix them with the current timestamp and put them on a new line. The problem is that if myscript produces no output, then because echo produces a new line, I'll get a log entry with just the timestamp on a new line.I want to do this all on the cron line. I do not want to have to modifymyscript.

How to create Cron job for every two hours starting from time from 6am to 6pm PST ? Any possibility of excluding weekends?

You can just run the same job at an interval of every 30 minutes so that it covers all the timezones. This should work:# run this every 30 minutes
time_zones_with_23 = ActiveSupport::TimeZone.all.select { |tz| tz.now.hour == 23 }.map { |tz| tz.tzinfo.name }
user_list = User.where(time_zone: time_zones_with_23)
|
I want to schedule a cron job that would send emails to all users as soon as deadline for their events ended. Note: Every user have different timezone.The approach i was thinking about:
I have a cron job that will run every day at 11 PM of UTC. This approach does work but every user will receive email according to UTC i.e at 1am, 3am or 4pm. Not according to their timezone.* 23 * * * 'UTC'

In your use case, you have to deploy your python somewhere.If the script takes less than 1H, deploy it onCloud Run JobsIf not, prepare aBatch configurationfor your scriptIn both case, I recommend you to use container to package your code.Then you have to schedule that runtime.Call theCloud Run Job execution APIdirectly with Cloud Scheduler (Be careful, for now, you can't send parameters to your jobs, only trigger a run)Call theBatch APIdirectly with Cloud Scheduler and with the config in the body

There is no difference between the root user and root permissions. All scripts inroot's crontab will run asroot, and all commands therein will also run asroot, with all associated permissions.
|
If a crontab is created for the root user under Linux, usingsudo crontab -e, then anything that's directly run by the crontab will use root permissions - seeIs it possible to make a Bash file run as root in crontab?Does this mean that any commandswithinthe bash script will also inherit root permissions, or will any commands within the bash script need to be explicitly executed with root permissions e.g.sudo docker ps?
|
Do commands run with root permissions, if they're inside a bash script that's executed via a crontab under root
|
I think the best way is to create a script that reads you .env file an runs the command, like this:#!/bash
# This is /my_path/my_script.sh file,
# do not forget to set executable permission by chmod
# Reading vars
. /my_path/my_env.env
# Calling the command
curl -Ssi -X POST -u "${variable1}:${variable2}" https://example.com...and your crontab line will be like this:2 11 * * * /my_path/my_script.shor alternatively in not so readable manner, directly in the crontab:2 11 * * * . /my_path/my_env.env; curl -Ssi -X POST -u "${variable1}:${variable2}" https://example.com...

AWS uses the extended CRON expression format:Please notice, there are 6 fields in the expression:Minutes,Hours,Day of month,Month,Day of weekandYear.In your case, you provide only 5 values. I'm guessing you were most likely usingcrontab.guruto create your cron expression, meaning that you want an event to fireAt 00:00. In that case, for AWS you would want to have something like this:0 0 * * ? *.

I did exactly the same you do and works. However, I cannot see how is the other parts of your code. Here is the complete code.app.module.tsimport { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { ScheduleModule } from '@nestjs/schedule';
@Module({
imports: [ScheduleModule.forRoot()],
controllers: [AppController],
providers: [AppService],
})
export class AppModule {}app.service.tsimport { Injectable } from '@nestjs/common';
import { SchedulerRegistry } from '@nestjs/schedule';
import { CronJob } from 'cron';
@Injectable()
export class AppService {
private readonly logger = new Logger(AppService.name);
constructor(private schedulerRegistry: SchedulerRegistry) {}
async testCron() {
const job = new CronJob('2 * * * * *', () => {
this.logger.log('My cron running...');
});
this.schedulerRegistry.addCronJob('sec', job);
job.start();
}
}And here is the consult using Postman:GET http://localhost:3000/cronThen is printed in the console. Pay attention it's not printed each 2 second but every second 2.[Nest] 15287 - 05/20/2022, 6:13:02 PM LOG [AppService] My cron running...

I am trying to implement cron in Nest application. I am adding cron dynamically as per the documentation as I want to perform some cron operation based on POST request. So for that I have added cron dynamically usingSchedulerRegistrybut when I am making POST request cron is not running.Below is my code:app.controller.tsimport { Controller, Get, Post } from '@nestjs/common';
import { AppService } from './app.service';
@Controller()
export class AppController {
constructor(private readonly appService: AppService) {}
@Post('cron')
testCron(){
return this.appService.testCron();
}
}app.service.tsimport { Injectable } from '@nestjs/common';
import { Cron, Interval, SchedulerRegistry } from '@nestjs/schedule';
import { CronJob } from 'cron';
@Injectable()
export class AppService {
constructor(private schedulerRegistry:SchedulerRegistry){}
async testCron(){
const job = new CronJob('2 * * * * *', () => {
console.log("My cron running...");
});
this.schedulerRegistry.addCronJob('sec',job);
job.start();
}
}Why this cron job is not running on POST request as console statement is not showing?

Make your script run every 30 minutes. On success, check if it is 11am before outputting success.if [ $Status == "200" ]; then
if [ $(date +%H%M) == "1100" ]; then
echo "success"
fi
else
echo "error"
fiNote: This checks for exactly 11:00 am. If your script may take longer than 1 minute to reach this point, save the time somewhere at the beginningtime="$(date +%H%M)"and check against it afterwardsif [ "$time" == "1100" ].Alternatively, if you want to keep the actual time at which to behave differently outside the script, you can introduce a parameter that is set only (or in one way) on the 11 am run, but not (or in another way) on the other runs.This requires you to still have multiple cron jobs, but with different parameters to the same script.0 11 * * * /home/username/script.sh yes
30 11 * * * /home/username/script.sh no
*/30 0-10,12-23 * * * /home/username/script.sh noWithin the script you need to check the parameter provided.printsuccess="$1"
if [ $Status == "200" ]; then
if [ $printsuccess == "yes" ]; then
echo "success"
fi
else
echo "error"
fi
|
First script runs once everyday at 11am and notifies that everything is working fine with "success" message.if [ $Status == "200" ]; then
echo "success"
else
echo "error"
fiSecond script runs every 30 minutes and doesn't print anything unless there's an error. Basically it keeps on checking every 30 minutes if everything's working fine and notifies me of an error only if anything is down.if [ $Status != "200" ]; then
echo "error"
fiBoth the scripts have almost exactly the same code. But I'm using 2 different scripts because of different outputs I want at different times. So is there a way to combine both the scripts?To be more clear, if possible, I want a single script that can send a success message everyday at 11am while also running every 30 minutes without sending that success message again and again and then only send error message if anything's down.In crontab it's like this:0 11 * * * /home/username/script1.sh
*/30 * * * * /home/username/script2.sh

The*/5syntax means "every 5 units, starting from 0". So, if you use it in the hour position, it will match hours 0, 5, 10, 15, 20.I'm assuming what you actually want is a strict 5 hour interval. So after hour 20, you want the next run to be at 20 + 5 hours, so at 1AM not midnight. If that's correct, there isn't an easy way to make cron work like that. It can do even intervals of all divisors of 24 though: every 2 hours, every 3 hours, every 4 hours, every 6 hours, every 12 hours.To get the 5 hour interval, one possible workaround is toschedule the cron job to run every hourat the start of your script that the cron job runs, add extra logic tocheck if it should run this hour. For example, you could take the current time, and calculate the hours since epoch. And exit early unless the calculated number is divisible by 5.

Executing the pipeline during the last 6 days of the month:Since not every month would have 31 days, you want to execute the pipeline on the last 6 days independently from the number of days in the month.Azure pipelines useNCrontabwhich does not provide support for specifying days relative to the end of the month as confirmed by the author inthis issue.One possible solution (following the suggestion inthe following comment) is to use a range of days that include the last six days in the worst case (February ending on the 28th) which you would express as23-31.Then, you must have a task in your pipeline that checks that the current date is within the range of the last 6 days of the current month, and stop the pipeline if it is not.As a result, your pipeline will be executed for the last 6 days of the month in the best case and for the last 9 days in the worst case but this will be handled by the additional task explained in the previous sentence.Running the pipeline using schedule triggers:If you want to run your pipeline by using schedule triggers, you need to disable PR and CI triggers.pr: none

The easiest way to "make a copy of an instance" is tocreate an Amazon Machine Images (AMI).The AMI takes a copy of all disks attached to the instance.Then, you canlaunch a new instance from the AMIand the new instance will have an exact copy of the disks from the original instance. This includes the operating system, applications, data, cron settings, etc because the disk was totally copied.See:Create an Amazon EBS-backed Linux AMI - Amazon Elastic Compute Cloud

Since you want from 0 to 30 minutes, all you have to do is instead of every minute in the expression change it to 0-30 minutes with every 5 minutes step.0-59/5 5-6 * * *You can refer tohttps://crontab.guru/for checking next values also. Since it gives only 5 next values, you can change the step up from 5 to 20 for better clarity.

You probably already got an answer or given up.
Anyway for future reference:
Yes, the package you are trying to install is amd64, you just need to download the correct architecture one.
In the release section you can find the ARM package, it works fine on Raspihttps://github.com/cronitorio/cronitor-cli/releases/tag/28.7
|
i'm trying to use cronitor (a server that monitors you cron jobs) on my raspberry pi zero.
The installation process for cronitor given in the doc fails when I run the last line:# Install CronitorCLI

sudo tar xvf cronitor-stable-linux-amd64.tgz -C /usr/bin/
sudo cronitor configure --api-key [[[my private key here]]]I get this error/usr/bin/cronitor: 2: /usr/bin/cronitor: Syntax error: Unterminated

First of all you don't need to query every second because the cron has only a one minute resolution.Next, comparing a cron scheduler expression to a timestamp is not a trivial task.
I'm not aware of any PostgreSQL module that would be able to parse the cron expressions.There are two options, either you write your own function to do the comparison, or else you use a external library in the programming language you are using to do the comparison outside of the Database.Here you will find an example implementation of such a function for Oracle that could easily be ported to PostgreSQL:SQL Query to convert cron expression to date/time formatIt is incomplete because it doesn't handle complex expressions like */5 or 5,10,15 for individual fields of the cron expression but this is where I would start.
|
I'm building a cron-as-a-service, to allow users to input their cron expression, and do some stuff periodically.Here's a simple version of my table:create table users (
id serial not null primary key,
-- `text` seems the most straightforward data type, any other suggestions?
cron text not null,
constraint valid_cron_expression CHECK (cron ~* '{some_regex}'),
-- snip --
-- maybe some other fields, like what to do on each cron call
)My backend runs a SQL query every minute. How can I query all the rows whosecronfield match the current timestamp (rounded to the closest minute)?Edit: users input thecronfield as acron expression, e.g.5 4 * * *.Edit 2: corrected the fact that cron time resolution is minute, not second.

Use*/2for day of the month, like so:01 23 */2 * * command_nameThis runs at 23:01 on the 1st, 3rd, ..., 31st of every month.To run two cron jobs on alternate days:01 23 1-31/2 * * command_name1
01 23 2-30/2 * * command_name2SEE ALSO:The time and date fields are:field allowed values
----- --------------
minute 0-59
hour 0-23
day of month 1-31
month 1-12 (or names, see below)
day of week 0-7 (0 or 7 is Sunday, or use names)A field may contain an asterisk (*), which always stands for
"first-last".
...
Step values
are also permitted after an asterisk, so if specifying a job to be
run every two hours, you can use "*/2".

The server is in MST standard time... I want thescript.phpto run from 6:00 AM IST to 7:00 PM IST.Ok, so...06:00 IST is 17:30 MST (previous day)19:00 IST is 06:30 MST (same day)This presents two problemsIt crosses the midnight boundary, andThe 30 min part of the offset makes it very difficult to create a repeating 15 minute pattern that starts / stops at the right time.The easy option is to ask your hosting provider to configure your server's timezone or try and use theCRON_TZenvironment variable if available (probably not with Godaddy).CRON_TZ=Asia/Kolkata
*/15 6-18 * * * /usr/local/bin/php -q /home/ddruva/public_html/site_data/script.phpOtherwise, you're left with something (ugly) like this# 5.30pm and 5.45pm
30,45 17 * * * /usr/local/bin/php -q /home/ddruva/public_html/site_data/script.php
# Every 15 minutes from midnight till 6am and from 6pm till midnight
*/15 0-5,18-23 * * * /usr/local/bin/php -q /home/ddruva/public_html/site_data/script.php
# 6am and 6.15am
0,15 6 * * * /usr/local/bin/php -q /home/ddruva/public_html/site_data/script.phpWith this approach, you're probably going to run into issues when your server changes between standard and daylight savings time and to be honest, I don't really have an answer for that.

Anyone know why it creates these tilde (~) files?That would be because of the-boption you are specifying torsync. Its purpose is to request exactly that (creation of backup files for destination files that are being replaced).Also anyone know a quick way to delete them?If there is no subdirectory structure to deal with (for example, if you have presented the full list of files), thenrm /path/to/the/directory/*~would be sufficient. If you need to clean up backup files in subdirectories of that directory, too, thenfind /path/to/the/directory -name '*~' -deletewould handle it.

A more 'canonical' way to tackle this problem in .Net is using the Task Parallel Library instead of manually controlling threads. The console program below illustrates how you would run 6 threads on background threads, with a one second delay between them.class Program
{
public async static Task Main()
{
var cts = new CancellationTokenSource();
List<Task> tasks = new List<Task>();
for (int i = 0; i < 6; i++)
{
tasks.Add(Task.Run(() => DoWork(cts.Token), cts.Token));
await Task.Delay(1000);
}
Console.WriteLine("Press ENTER to stop");
Console.ReadLine();
Console.WriteLine("Waiting for all threads to end");
cts.Cancel();
await Task.WhenAll(tasks);
}
public static void DoWork(CancellationToken token)
{
while (!token.IsCancellationRequested)
{
Console.WriteLine($"Doing work on thread {Thread.CurrentThread.ManagedThreadId}");
Thread.Sleep(10000); // simulating 10 seconds of CPU work;
}
Console.WriteLine($"Worker thread {Thread.CurrentThread.ManagedThreadId} cancelled");
}
}Asynchronous programming using the Task Parallel Library is explained pretty wellin the documentation

This cron will run every minute and task will be bound with condition.
If you need different cron job then you can generate using thiswebsite.@Scheduled(cron = "0 0/1 * 1/1 * ? *")
protected void performTask() {
if (condition)//if value matches with database value
{
//perform the task
}

Look at running a cronjob inside the pod instead of kubernetes CronJob. That way you don't have to bother about launching a new pod every minute.
|
I'm starting in Kubernetes and I have a question about the CronJob, in my project I need a cron job to be launched every minute. On many tutorials people use the CronJob resource, I set it up and I see that every minute a pod is created to perform the command and is then destroyed, and that indefinitely.
I wonder if in my case (every minute) it's interesting to use the Kubernetes CronJob resource knowing that every minute a pod is created by pulling an image etc.... I find the process a bit cumbersome, isn't it better to have a simple pod executing the cron in the traditional way?

Put the argument toechoin single quotes rather than double quotes, so there won't be any evaluation of$(...)inside it.There's also no need to includecrontab -rin the command that's piped tocrontab -.bash -c "crontab -r; echo '* * * * * /usr/bin/wget -o /backups/\$(date +\%F_\%R).sql 127.0.0.1:8000/api/export/full' | crontab -"

I'm using a bash oneliner to create a cronjob that saves files to a path that depends on the current time, hence I'm usingdate.

What you are doing now is scheduling a job to run twice daily.
However, you can alsomanually dispatch a jobto run at that instance (or as soon as a runner is free to handle your job).You can create a controller action so that when the button is clicked, the controller dispatch the job. For example,<?php
namespace App\Http\Controllers;
use App\Jobs\ResendAttachment;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class ExampleController extends Controller
{
/**
* Resend attachment.
*
* @param Request $request
* @return Response
*/
public function resendAttachment(Request $request)
{
ResendAttachment::dispatch();
}
}

Generally speaking (python) Script is location-sensitive. This is related to always using absolute paths in a script, but not quite the same. Your cron job may need to cd to a specific directory where the script is stored before running it.When Cronjob runs it uses your home directory as current directory. So if you were to put your script in your home directory, it will work. In this case the script was using a relative path, assuming that it was relative to the location of the script but it was in fact relative to the root of your home directory because that was the working directory that cron was using, which is why the script worked when it was in the root of my home directory.So if you have to run it in a directory other than your home directory, in your cronjob you will need to cd to your script directory and run it as in this example:* * * * * cd /var/www/clientfolder/ && /usr/bin/python /var/www/clientfolder/your_python_script.py >> /var/www/clientfolder/your_python_script.logit is important you understand why. It should now work!If you have other issue not related to Script Execute Environment you may want to read this very good articleCronJob not runningSource:https://www.digitalocean.com/community/questions/unable-to-execute-a-python-script-via-crontab-but-can-execute-it-manually-what-givesBest of luck

As quoted in crontab manual"The time used for writing into a log file is taken from the local

Does Cron have a way to include all except one case

I think you might need to rethink why you actually need a cron job.
Why do you have old log files inside of your container? One of the best practices with building applications inside containers is the fact of logging everything towards stdout/stderr. This way you keep the paradigm of 1 container = 1 process and your log management is a responsibility of docker and/or your host.You can do this fairly easy by either:reconfiguring your application to log to /dev/stdoutlinking your application log file /var/log/nginx/access.log to /dev/stdout in your dockerfileln -sf /dev/stdout /var/log/nginx/access.log
ln -sf /dev/stderr /var/log/nginx/error.logIf you actually need to log towards a location inside your container, a good practice could be to log towards a shared volume. Then run a cron job that spins up a container which also mounts this volume and cleans the logs. You can schedule this clean-up container with a cron job.If you use some kind of orchestrator like Kubernetes it'd be done with a Scheduled pod which does exactly this.
|
Suppose I have a Docker container with Nginx or PostgresQL. I need Cron to delete old log files. Where should I run cron? In the same container inside an entrypoint script? In its onw container? Outside docker?Running in outside Docker will defeat Docker's control over configurations. I will have to use some other configuration management system to pin its config.
|
Should I separate cron into its own docker container?

I could not understand what you mean "the first log". Maybe the first line of logs?To run something in the background when SSH connection is closed, I prefer Linuxscreen, a terminal simulation tool that help you run your command in a sub-process. With it, you could choose to view your output any time in the foreground, or leave your process run in the background.Usage (short)screenis not included in most Linux distributions. Install it (Ubuntu):$ sudo apt-get install screenRun your script in the foreground:$ screen python3 my_script.pyYou'll see it running. Now detach from this screen: Press keysCtrl-Afollowed byCtrl-D. You'll be back to your shell where you run previousscreencommand. If you need to switch back to the running context, usescreen -rcommand.This tool supports multiple parallel running process too.Something weirdI've tried to redirectstdoutorstderrto a file with>or>>symbol. It turned out in failure. I am not an expert of this either, and maybe you need to see its manual page. However, I tend to directly write to a file in Python scripts, with some essential output lines on the console.
|
So, I have a python script which outputs some data into terminal from time to time. Im trying to run in on the Ubuntu VPS even after I close the SSH connection and still keep the logs somewhere.Im saving the logs by using:python3 my_script.py >>file.txtand it works perfect, however when I try to run this process usingnohup python3 my_script.py >>file.txt &so it runs in the background and after the ssh connection is closed it seems to save only the first log outputted from my_script.py. I've also tried running this incrontabbut the result is similar - only the first log is saved.Any tips? What am I doing wrong?

Thanks for everyone that took the time to answer. So the problem was not with crontab at all but was actually an issue with Python virtual environments. Usingsource activatewas not working with crontab. The solution was to modify the shell script so that it directly uses the Python in the specified virtual environment. For example..#! /bin/bash
cd /home/pi/scripts
/home/pi/berryconda3/envs/myEnv/bin/python pyscript.pyAlso I had logging done within Python but because it crashed early in the script they were never written so I incorrectly assumed the crontab was not executing correctly. I have since discovered that it is a very good idea when working withcrontabto log what's going on directly from cron like this...* * * * * /home/pi/bash/myshell.sh >> /home/pi/logs/cronlog 2>&1This way I could actually see what was going wrong (i.e. Python was throwingModuleNotFoundError).There's a much better answer on this herethat is worth looking at.

This question already has answers here:Cron and virtualenv(20 answers)Closed4 years ago.Struggling to getcrontabto execute a shell script on my Raspberry Pi. The script runs fine if executed with bash (it's executing a python script that runs in a virtual environment).Here's what I've triedcrontab -e* * * * * /home/pi/bash/myshell.shAnd the shell script...#! /bin/bash
cd /home/pi/projects/scripts
source activate myEnv
python pyscript.py
source deactivateThis works fine...bash /home/pi/bash/myshell.shI also tried editing the root cron tab file directly withsudo nano /etc/crontabbut this also didn't work. What am I missing here?

I want to have more control over a time consuming cron job running on a server. That is, be able to see progress, stop running code if necessary and etc..I thought that this would be possible using a tmux session, but I can not figure out how.I know that you can start new tmux sessions and run code inside it like this:tmux new-session -d -s session_name "some code"I've tried the obvious solution like this:tmux new-session -s session_name
**exit session**
tmux a -t session_name "some code"Is this even possible? Any advice is appreciated.

I have a rather weird issue. My aim is to use ffmpeg to grab a screenshot from a home CCTV cameras rtsp stream every hour. I want to do this in order to make a timelapse. However everyday from 11am to 12am (the next day) there are no snapshots saved.On an always on Debian machine, this is the shell script I have that crontab calls:dt=$(date +"%d%m%2y%I%M%S")
ffmpeg -rtsp_transport tcp -i "rtsp://IP:554/..." -frames 1 /user/snapshots/ch1/$dt.jpgRunning it by itself works fine and saves a jpg snapshot successfully to the right folders.Incrontab -eI have the following line:0 * * * * /bin/sh //user/snap.shThanks.

You could usemarshal.dump(https://docs.python.org/3/library/marshal.html) to save the value when stopping the program, and then loading it viamarshal.loadwhen starting.Honestly, I think it would be a much better approach to fix the root cause of the problem, i.e. solving the exponential run time.
|
I have a program written in python which goes as follows:for i in range(4954):
........
save("/Downloads/pos_" + str(i) + ".h5")The fact is the program running time increases exponentially(we observed it usingtime.time())So what I need is run the program for 10 min and then re run the program.
But I just need to change the i in for loop to the number at which it is stopped.
I can do a cron job, but what should I do to changeivalue?

Its not only WP, it can happen in any framework. It's more like a generalized question. Here is what I propose you do:Check your error logs. maybe you are having memory limit issues. If its the case, make sure you have memory_limit set something high like 256 or 512M.Put various custom log messages in your function and record it into a separate log file so that you at least know till where it runs and where it stops.Whatever requests you make to external apis like youtube, put it in to a try catch block to catch any exceptions and log them too.Hopefully you will can debug it that way, good luck!
|
So i'm making a plugin that uses the youtube V3 api to bring videos from our youtube channel and turns them into posts for our site.I'm using WP Cron for this. Basically every 12 hours it checks to see if there are any new videos, if there are new videos them it uses the YouTube V3 API to turn them into posts.Everything seems to be working fine except for one thing, which is when WP calls the cron job, the full function does not happen.It should be pulling in about 4 videos. It only pulls in one.Also for some reason the iframes that it puts the videos in inside fo the page don't show up.But when I call the cron job manually using the Cron Manager Plugin
"Advanced Cron Manager" everything works as it should.I can confirm that the function works.I can also confirm that when I tell wordpress to run the cron job that it works.Its only when WP decides to run the cron job by itself that the function does not work. It does run. And it does do some of what the function should do, just not everything.So my question is not so much "why is the youtube api not working" or "why is my cron job not running", But why would a wp cron job work when manually called but not when wp calls it?

Previously you could setup up Cron jobs using Google App Engine which tigger a PubSub triggered Google Cloud Function, however, this defeated the 'serverless' approach as you are introducing infrastructure to manage and it can take a moderate amount of work to setup the Cron jobs.You can now use the newly releasedGoogle Cloud Schedulerwhich is completely managed, cheap and which makes it very easy to create scheduled jobs via Google PubSub and via HTTP requests. These in turn can trigger the Google Cloud Functions at regular intervals per unit of time or at a specific time of the day/week/month down to a one-minute interval.Note that you are still required to have an App Engine instance in one of the supported regions.

Crontab Permissions:There are two files that control the permissions for crontab:/etc/cron.allowand/etc/cron.deny.If there is acron.allowfile, then the user or users that need to use cron will need to be listed in the file. You can usecron.denyto explicitly disallow certain users from using cron.If neither files exist, then only the super user is allowed to run cron.Well, that depends on the system specific configuration to be exact. Most configuration do not allow any users to run jobs, while some systems allow all users to run jobs by default.So, the first step is to create a file namedcron.allowin the/etc/folder. Add the user name to this file in order to allow the user to run jobs.Once the proper permissions has been set, the user should be able to modify and run jobs using thecrontabcommand.

Is it possible (and what would be the most simple solution), to schedule (like a cronjob) the launch of symfony function ?I would also need to secure it and launch then as anSUPER_ADMIN_USERof my website (using FOSUserBundle).I saw that this is possible to integrate the unix cronjobs (but is there a solution inside symfony ?). Also I could not find information about the rights.

On a Redhat OS, I have a script that launches a Java program. This script can be started from the command line but is launched (periodically) by crontab as well.Within this program, I need to know how the program was started. This because the output is written either to STDOUT (if started from the command line) or in a logfile (if launched by crontab).First I thought I could useSystem.console().The problem is that this method returnsnullalso if the program was started from the command line but with STDIN and/or STDOUT redirected.Any idea how to resolve this?I triedHow can I check if a Java program's input/output streams are connected to a terminal?but that doesn't answer my question.

This question already has answers here:CronJob not running(19 answers)Closed3 years ago.I'm new to freeBSD.
I just set up a server and installed python 3.6.
Now i want to have a python script run every day at 15h00, so i tried to set up a cron task.
But in some way, the cron task never runs or is giving me errors.
Since cron uses mail to report errors and mail doesn't seem to be installed on my server, I have no clue whether the script actually runs or is not running at all.
The line added in /etc/crontab is the following:0 15 * * * root /usr/local/bin/python3.6 /root/myscript.pyWhere /usr/local/bin is the directory where python is installed.
When running this command in the normal command line, it works perfectly, but with cron, it keeps not working.
Any help is welcomeThanks in advance

Im using a bash script (sync.sh), used by cron, that is supposed to sync a file to a MySQL database. It works by copying a file from automatically uploaded location, parse it by calling SQL script which calls other MySQL internally stored scripts, and at the end emails a report text file as an attachment.But, seems like something is not working as nothing happens to MySQL databases. All other commands are executed (first line and last line: copy initial file and e-mail sending).
MySQL command when run separately works perfectly.
Server is Ubuntu 16.04.
Cron job is run as root user and script is part of crontab for root user.Here is the script:#!/bin/bash
cp -u /home/admin/web/mydomain.com/public_html/dailyxchng/warehouse.txt /var/lib/mysql-files
mysql_pwd=syncit4321
cd /home/admin/web/mydomain.com/sync
mysql -u sync -p$mysql_pwd --database=database_name -e "call sp_sync_report();" > results.txt
echo "<h2>Report date $(date '+%d/%m/%Y %H:%M:%S')</h2><br/><br/> <strong>results.txt</strong> is an attached file which contains sync report." | mutt -e "set content_type=text/html" -s "Report date $(date '+%d/%m/%Y %H:%M:%S')" -a results.txt --[email protected]

A cronjob runs in a limited environment under/bin/sh. What is probably happening is that the default core-dump size is set to zero.
I do believe that this can be seen and configured in/etc/security/limits.conf, however the easiest way to check this is to run the following cronjob :* * * * * ulimit -a > ~/cron.ulimit.txtIf the file~/cron.ulimit.txtindicates a core-file size ofzero blocks, then the cron-job will never generate a core file.You can create a core file by running a wrapper scriptwrapperwhich sets the ulimit for the core-file size. Eg.#!/usr/bin/env bash
ulimit -c unlimited
/path/to/binaryThis script can then be ran as a cronjob.

I'm running Ubuntu 15.04 on a MicroZed where I'm executing a program that dereferences a null pointer from a crontab script.

In the SilverStripe 3 version of Fluent you can useFluent::with_localeto perform a callback under the context of a given locale, e.g.:Fluent::with_locale('de_DE', function () {
$myObject = MyObject::create();
$myObject->Title = 'German title';
$myObject->write();
});For reference, in the SilverStripe 4 version you can do this instead:FluentState::singleton()->withState(function (FluentState $newState) {
$newState->setLocale('de_DE');
// ...
});

You have to make a shell script which will do the steps of changing to script directory, activating virtual environment and then running it.Example:#!/bin/bash
cd $YOUR_DIR
. venv/bin/activate
python3.4 test.pyThen you call this script in cron with/bin/bash /.../script.shWhat you could do additionally ischmod +x test.pyand add/update first line to:#!/usr/bin/env python3.4This way you can just run Python script with./test.py

I tried to make a cron job on crontab which runs a python script on AWS ec2. My python script includes a module that is only available for python3.
Using the following command I changed the ec2 default python interpreter from python2.7 to python3.4
Source /home/ec-2user/venv/python34/bin/activate
and then using pip install, I installed the required module for python3.4. So now the default interpreter is python3.4 and when I run the script on ec2-user directory using the following command:
python test.py
the program runs without any problem (so I am sure the module is installed correctly).
But when I assign python file to a cronjob
* * * * * python test.pyIt does not work. Checking the mail, the error is:
“No module found named “xxxxx” “But as I said it worked fine outside of the cron.I was wondering if you can help me with this problem. I appreciate your time and information.

0 0 * * */1 wget -t 1 - "http://urlto.job/job9" -O ->> home/password_reset_log.txtAll of this works, however I am trying to carry out the seemingly menial task of adding a new line to each entry in the text file.Currently I get:{"error":0,"result":"Password reset email successfully sent to 0 users, 0 emails failed to send","jDateLastRun":"10 Jan 2018, 00:00:07","jHandle":"check_password_resets","jID":"9"}{"error":0,"result":"Password reset email successfully sent to 0 users, 0 emails failed to send","jDateLastRun":"10 Jan 2018, 00:00:07","jHandle":"check_password_resets","jID":"9"}So all the entries are on a single line. What I want is:{"error":0,"result":"Password reset email successfully sent to 0 users, 0 emails failed to send","jDateLastRun":"10 Jan 2018, 00:00:07","jHandle":"check_password_resets","jID":"9"}
{"error":0,"result":"Password reset email successfully sent to 0 users, 0 emails failed to send","jDateLastRun":"10 Jan 2018, 00:00:07","jHandle":"check_password_resets","jID":"9"}So all the entries start on a new line (easier to read and see which jobs ran successfully and which failed and the result of each time the job ran).Is there a simple way to do this (perhaps adding a parameter to my cron command).

cron & wget adding new line to each document write

You can't because controllers are bound to HTTP.However, you can refactor your code and extract the email sending logic to a mailer, and call that mailer from both your controller and your rake task.
|
So a bunch of mailing methods in Article controller, that mix different types of articles with different users. All work fine when called from somewhere within Rails. But they need to be executed during the week by cron. What goes in place of "xxxx" in the rake file to tell it to execute the "10_am_action" method in the Article controller?articles_controller.rb:def 10_am_action
[sends the right e-mails to the right users]
endCron:0 10 * * 0 cd /data/website/current && RAILS_ENV=production bundle exec rake emails:10_amemails.rake:namespace :briefings do
desc "10 am e-mails"
task :10_am => :environment do
xxxxxx
end
end

Rails: how do you tell cron to execute a controller method?
|
This is a shot in the dark, but make sure you are starting a database connection in your CRON job. Otherwise you won't be able to execute any queries.

I'm having this weird situation where my Cron Job is successfully executing a function that returns a promise, however, when it tries to execute a.find()on the Model, it never actually executes. I have this same function used elsewhere in my app and is called via an API call and returns no problem. Is there something I'm missing?Here is my cron script:var CronJob = require('node-cron');
var TradeService = require('../services/TradeService');
// Setup the cron job to fire every second
CronJob.schedule('* * * * * *', function() {
console.log('You will see this message every second');
TradeService.executePendingTrades();
}, null, true, 'America/Los_Angeles');Here are the related functions that get called:exports.executePendingTrades = () => {
// Get all pending trades
exports.getPendingTrades().then(results => {
console.log('results', results); // This never fires
})
}
exports.getPendingTrades = () => {
return new Promise((resolve, reject) => {
Trades.find({})
.where('is_canceled').equals('false')
.where('is_completed').equals('false')
.sort('-created_at')
.exec( (err, payload) => {
if (err) {
return reject(err); // This never fires
}
return resolve(payload); // This never fires
})
});
}

Well, I assume you use the r-base image. If you just need your R script to run in the currently existing container, just create a new cron entry in your host using thedocker execcommand.Example* * * * * docker exec -it $instanceName Rscript yourScript.R

It depends on what your exact Javascript needs are, but unfortunately, if your application truly depends on a browser (and can't be ported to something more appropriate for the constraint), you will need to "fake" the browser somehow. Here are a few options.PhantomJSis basically a headless Webkit engine (think Chrome or Safari).HtmlUnitfor a Java based solution, supported/developed by MozillaOther rabbit holes(Wikipedia/Headless Browser)NodeJSoffers a non-browser, headless, Javascript specific option, but will require your code to be more robust and generic than many code bases initially are when originally coded for browsers.

I have an application that I need to deploy that is a mix of pure PHP, JavaScript, jQuery, and AJAX. It runs flawlessly on all machines when called in a browser. Unfortunately, I also need to deploy this application to a machine that won't be able to run a browser.Just running the file using PHP will output the resulting file, but does not execute any of the Javascript.What are my options to get this task running? The machine will have access to xampp, but not to a browser.Edit: the application grabs data from MSSQL, uses Javascript to turn that data into charts, uses an AJAX call to save those files to disk, and then calls another PHP script to mail a copy of the resulting files.

At first I suspected that CVS run from crontab couldn't findrshdue to difference inPATHvariable in login shell and incronenvironment.I was wrong, the answer is to setCVS_RSHtosshin script run from crontab, as original author figured out. This is because CVS being really old defaults torshas remote shell. But asrshisn't secure, probably most administrators of CVS repositories require connection with a secure shell,ssh.Credit goes to:https://bugs.archlinux.org/task/12636#comment42630

flock -n LOCK-FILE COMMANDIn your case:-n: if flock cannot obtain the LOCK-FILE, i.e. it already exists, it will stop right there, and not execute the COMMAND.So the -n ensures only one instance of COMMAND can run at a time.in your case LOCK-FILE is /var/www/vhosts/SOMEDOMAIN/scripts/blia_bab_import.sh.lockThe LOCK-FILE is what you decide it to be. flock will check for that file as a lock. It could be named anything, anywhere on your system, but doing it this way is nice since you know what the .lock file is used for.To illustrate, you could do flock -n /tmp/some_lock_file.txt script.sh. The value is not enforced, you decide what you want to use.COMMAND in your case is /bin/bash /var/www/vhosts/SOMEDOMAIN/scripts/blia_bab_import.shThe script you want to execute is the value of COMMAND, so again for you: /bin/bash /var/www/vhosts/SOMEDOMAIN/scripts/blia_bab_import.sh/bin/bash is to specify that the script blia_bab_import.sh must run inside a bash shell. You could do without by using the #!/bin/bash first line in your .sh file.

I have this cronjob, that is not working for some reason, but I don't entirely understand what it does, could someone explain?flock -n /var/www/vhosts/SOMEDOMAIN/scripts/blia_bab_import.sh.lock /bin/bash /var/www/vhosts/SOMEDOMAIN/scripts/blia_bab_import.shI googled that flock is supposed to lock the file and only run if it can lock the file, so that the job cannot run multiple times at the same time.What does the -n do?flock -nWhy is this a .lock file?/var/www/vhosts/SOMEDOMAIN/scripts/blia_bab_import.sh.lockI have no idea what the /bin/bash is supposed to do?/bin/bashIs this the script I want to execute?

On my Google App Engine app, it killed everything after 30 seconds regardless of if it's a cloud task or cron job.2 possible ways to get around it are:Use Async workers, see here:How can I run long tasks on Google App Engine, which uses gunicorn?, I haven't tried it.Or change the timeout for the synchronised workers, here is my app.yaml '--timeout=600' sets the gunicorn worker timeout.

I'm not familiar with cPanel, so I can't address that aspect of the question, but, from the Perl side, I can tell you that deleting the cron job will do no (additional?) harm. Because there's a syntax error in the Perl code, the checkupdates program is already not running (and, indeed,can'trun).Checking with any appropriate vendor to see whether they can provide a fixed copy ofCpanel::JS::Variations(the source library which contains the actual error) would likely be a good idea, as it may be used by other pieces of Cpanel which actually are important, but the cron job isn't doing anything other than generating email to tell you it failed.

One of the automatically generated cron jobs, namely:2 0 * * * /usr/local/bin/perl /usr/local/cpanel/3rdparty/quickinstall/scripts/checkupdates.ploutputs this:Bareword found where operator expected at /usr/local/cpanel/Cpanel/JS/Variations.pm line 20, near "$filename =~ s{/js2"
(Might be a runaway multi-line // string starting on line 19)
(Missing operator before js2?)
syntax error at /usr/local/cpanel/Cpanel/JS/Variations.pm line 20, near "$filename =~ s{/js2"
Global symbol "$filename" requires explicit package name at /usr/local/cpanel/Cpanel/JS/Variations.pm line 21.and many other errors.Would it be safe to delete this cron job? especially considering that:it is faulty in the first place;I don't have access to the Perl script in question and can't fix it;quickinstall modules (such as WP and Moodle) properly check for updates themselves.I'm using a shared hosting on HostGator and, as such, don't have a shell access; all I can do is work thru cPanel.

So I've been looking up cronjobs for the past few minutes... I have a general sense of how to add one to my websites ubuntu system.... I need to make my system run a corn job once a minute (according to the software I'm having it use).First I log in via SSH..Then I enter root mode.Then I type crontab -eThen each line is a scheduled cron job....The instructions on the softwares site says to just run the following command once a minute:/usr/bin/php -d memory_limit=-1 -d max_execution_time=0 /home/mywebsite.com/215a/applications/core/interface/task/task.php 8222157ad26eg58q51dh343ha7j472azI know that the start of the crontab line should read like this:*/1 * * * * /path/to/commandMy confusion is this.... Can I just put the instructed command in the /path/to/command part, or do I need to create a file and put the files address there? Also if I have to make a file, what format?

How do I write a cronjob?

Need to setup messaging for that.It’s common to use a persistent queue such as RabbitMQ. The microservice responsible for sending emails then consumes the messages from the queue and handles them appropriately.If you run into a problem of your single instance of email microservice not being enough you can simply fork another instance and deploy it instantly. This is because when a message from the message queue is consumed it’s gone unless you tell it to return (to be requeued). I.e. any successfully sent email will consume the the message hence the request to send an email is no longer within the system.
|
For example I want to have a microservice to send notifications(email, sms, push notification). Everything is ok for few users. After some time our application have a lot of users, so, this microservice doe not manage, and email a sent after 1 hour.So, how to handle this situation? Deploy another instance of microservice, but how to handle that only one microservice process one email and user don't receive multiple emails?

That sounds like your cron job is only runningartisan schedule:runonce per day. Make sure your cron job is set up like the docs:* * * * * php /path-to-your-project/artisan schedule:run >> /dev/null 2>&1The* * * * *part means run every minute, and then Laravel will decide which tasks to run each minute based on your schedule.

I have a cronjob getting a list of prices from a website in JSON format and copying it into the right folder and it looks like this:curl 'https://somesite.web/api/list.json' > ~/list.json.tmp && cp ~/list.json.tmp /srv/www/list.json > /dev/nullThe problem is that a couple of times the website was down while the cron was trying to get the list and got an empty JSON file. To prevent this in the future, is there a way to make the cron only copy the file if it's not empty (no cp option to do this)? or should I create a script to do that and call the script after getting the list?

It likely fails becausePATHis not set. You should set the PATH in theMakefileand export it:PATH := /usr/bin:/usr/local/bin:/some/other/dir
export PATHYou can test your command by specifying a very limited environment:/usr/bin/env -i PATH=directorylist_here HOME=$HOME your_cron_cmdPS: Usually any output on stdout and stderr is mailed to you by cron. Did you check your inbox for cron mails? These may provide additional clues.
The mails are sent to the mailbox of the user the crontab belongs to. So if this is run as root it will be in root's inbox. (Of course this will work only if stdin+stdout weren't redirected to/dev/null). On a Unix system, you can read the inbox mails with themailor maybemailxcommands.

You can useNode Cron, it is a Node package that allows you to schedule tasks.In this case, you could check every day if each post was created more than 7 days ago (or the time expiration the user set), and if it is, delete it.This is thepackage repowith the documentation of how to use it:Node Cron by merenciaI hope it helps you!

I'm building a website using MEAN stack. A user will post an item (and it will be stored to MongoDB) and I want to implement an expiry on that post. For example, they choose 7 days, after 7 days the user's post will be closed. How can I achieve that? It's like it will run a function to close the post based on how long the user sets it. I can't imagine how will I achieve it.How can I implement something that will automatically close the post of a user based on the days they set?

Cron jobs start with a very limited set of environment variables.
There's likely one or more environment variables you get from your ~/.profile or ~/.login (or the like).Try moving the whole job into a script and invoke it like this:22 * * * * /home/work/ui/mycronjobInmycronjobyou'd have something like this:#!/bin/bash
source ~/.bash_profile
cd /home/work/ui && /home/work/.jumbo/bin/python test.py >> result.logThat assumes your $SHELL is bash and you have a ~/.bash_profile.
If you have some other shell or other init file (~/.login, ~/.profile, etc) use that instead.

Is there a way to implement scheduling inside Rails without using Cron
or a better way of managing regular tasks that works well with Rails?Cron is pretty much the go to tool for running scheduled activities on *nix system and most gems actually leverage cron under the hood, in fact avoiding cron is probably a lot more work unless you want to use a third party service.One of the new features of Rails 5 isActiveJob:Active Job is a framework for declaring jobs and making them run on a
variety of queuing backends. These jobs can be everything from
regularly scheduled clean-ups, to billing charges, to mailings.
Anything that can be chopped up into small units of work and run in
parallel, really.It can be used with several backends:SidekiqResqueSucker PunchQueue Classic

I'm new to Rails so I'm not sure if this is a stupid question but...I have to run regular tasks to populate data to my Rails app. Today I use the whenever gem to create Cron entries to run these tasks on my system. I want to migrate my Rails app to Docker so that I can scale it more easily. I know that in Drupal(PHP) there is Poorman's Cron which uses requests to drive schedules.Is there a way to implement scheduling inside Rails without using Cron or a better way of managing regular tasks that works well with Rails?

If you start script with cron always use full path of file.Add to every path in your scriptdirname(__FILE__)and add/if necessary.

I have a PHP script that reads email, saves the attachments, read the saved csv files and load a DB with the content of the csv files.
I use the Jamesiarmes\PhpEws library to connect to my Exchange Server and all is working perfectly.
As I need to do it every day, I use crontab to run the PHP script every day at ten o'clock.00 10 * * * /usr/bin/php /home/web/update/format-recent-report.php > /home/web/log/readmail.log 2> /home/web/log/readmail.errThe problem arises when Crontab tries to run the script. The readmail.err file contains the following error:PHP Fatal error: Class 'jamesiarmes\PhpEws\Client' not found in
/home/web/update/exchange_config.php on line 8Here it is theexchange_config.php:<?php
use \jamesiarmes\PhpEws\Client;
$host = 'xxx.xxxx.it';
$username = 'yyyyy';
$password = 'zzzzzz';
$version = Client::VERSION_2010;
?>Afetr getting the error, I go to the directory where the script is located and try to run the script manually with:php format-recent-report.php > logand the script works correctly. Why this difference between crontab and manual ?I don't post the content of the PHP script because it is very long, but I can say that it starts with:include '../vendor/autoload.php';
include 'exchange_config.php';it stops at the very beginning.
