Perl copy command to wait for copy completion




I am copying the file from windowsLocation1 location to LinuxLocation1 as "windowsLocation1-> windowLocation2-> LinuxLocation1", windowsLocation2 is a swap space accessible from both windows and Linux machine.



```
copy("//server1/dir1/myfile.txt", "$copy\_dir/myfile.txt") or die "Copy failed: $!";
<telnet into Linux machine>
$obj->{telnet}->print( "sleep 10; cp /net/dir1/myfile.txt /tmp/files/");
#added "sleep 10, to avoid the race condition between copy and cp.

        

        
        
        
 (adsbygoogle = window.adsbygoogle || []).push({});
 
        

    
```

This "sleep 10" time is sometimes not enough and its throwing error as "cp: read error: I / O error" I think the second "cp" command is trying to access the file when the first "copy" command is all still writes. using Perl v5.6.1


Is there a way to avoid this? thank.
I'm going to assume that you are getting your routine `copy`
  




 (adsbygoogle = window.adsbygoogle || []).push({});
 
  

from a module `File::Copy`
  




 (adsbygoogle = window.adsbygoogle || []).push({});
 
  

.


After a quick search in CPAN, I came across a module named [`File::Copy::Vigilant`
  




 (adsbygoogle = window.adsbygoogle || []).push({});](https://translate.googleusercontent.com/translate_c?depth=1&pto=aue&rurl=translate.google.com&sl=ru&sp=nmt4&tl=en&u=)that seems to suit your needs and successfully test reports from perl 5.6.



  




 (adsbygoogle = window.adsbygoogle || []).push({});
 
  

I also found [`File::Copy::Reliable`
  




 (adsbygoogle = window.adsbygoogle || []).push({});](https://translate.googleusercontent.com/translate_c?depth=1&pto=aue&rurl=translate.google.com&sl=ru&sp=nmt4&tl=en&u=), but it only has reports up to perl 5.8, although that doesn't prove anything. You might just be a bit of a traveling pioneer as far as module goes ....
oh my god … i have to appologize very, very much for wasting your time. as so often the problem is sitting in front of the screen :frowning:

i am using certbot inside a script where i make a backup of the /etc/letsencrypt folder, stops apache, on so on …

my mistake is, that my backup of /etc/letse… PF1:  

Name 25 A  

Code 10 S 0  

Location 30 A


PF2:  

LCode 10 S 0  

LLocation 30 A  

LName 25 A


we can’t copy pf1 to pf2, because pf1 and pf2 field are interchanged. so we can’t copy..  

if you try to copy your records, it ll show like this ‘+++++++’ 


best you try to change field order like this.. (must change the field order PF1 or PF2) 


PF2:  

LName 25 A  

LCode 10 S 0  

LLocation 30 A


after using cpyf command… don’t forget the below step to fill….  

<b>Record format field mapping . . > *NOCHK</b> What is Delayed Branching ?
  

One way to maximize the use of the pipeline, is to find an instruction that can be safely exeucted whether the branch is taken or not, and execute that instruction. So, when a branch instruction is encountered, the hardware puts the instruction following the branch into the pipe and begins executing it, just as in predict-not-taken. However, unlike in predict-not-taken, we do not need to worry about whether the branch is taken or not, we do not need to clear the pipe because no matter whether the branch is taken or not, we know the instruction is safe to execute.

Moving $I\_1$ after branch


* $I1$ is updating the value of  $R2$
* $R2$ which is used to determine branch condition $R1$
* Value of $R2$ is available after branch
  

$\Rightarrow$ `Cannot be moved`


Moving $I\_3$ after branch


* value of $R1$ is computed in this instruction
* $R1$ is the branch condition
  

$\Rightarrow$ `Cannot be moved`


Moving $I\_4$ after branch


* $I4$ is simple store instruction used to store R1 in memory
* program execution will have no effect if this is placed after conditional branch
  

$\Rightarrow$ `Can be moved`


Moving $I\_2$ after branch


* It update the memory location to place the storing of conditional branch instruction $R1$
* If moved after branch , when compiler reaches $I4$ program execution will stop
  

$\Rightarrow $ `Cannot be moved`

I believe that you cannot use "CALL" to call a file which is not executable.  

same goes with SHELL...



Call Shell(AppName, 1) Where AppName contains the path of the Executable file.



try it with any other directory and try calling an executable.. it will work.



If you try calling a .txt or .bmp, it will give you the same error message... Hi,  

  

check the following Code  

SQLCopy Code

```
-- Question 1 Answer
SELECT E.EmployeeID,E.Day, (E.TotalTime/60) 'TotalHours', (E.TotalTime%60) 'Minites'
FROM (SELECT EmployeeID,CONVERT(VARCHAR(10),FromTime,102) 'Day',SUM(DATEDIFF(mi,FromTime,ToTime)) 'TotalTime'
      FROM tblEmployeeTimeCard
      GROUP BY EmployeeID,CONVERT(VARCHAR(10),FromTime,102))E

-- Question 1&2 Answer
SELECT E.EmployeeID,E.Day, (E.TotalTime/60) 'TotalHours', (E.TotalTime%60) 'Minites',
CASE WHEN (E.TotalTime/60)>=6 THEN E.TotalTime - (30* ROUND((E.TotalTime/60*6),1))
     ELSE (E.TotalTime/60) END 'TotalWorkHours'
FROM (SELECT EmployeeID,CONVERT(VARCHAR(10),FromTime,102) 'Day',SUM(DATEDIFF(mi,FromTime,ToTime)) 'TotalTime'

      GROUP BY EmployeeID,CONVERT(VARCHAR(10),FromTime,102))E
```
  

  

For ur Question 2, I am not getting. give some more details about that. if possible send some sample data. if access over lap like (From date is 2013 -04-05 11:55:00PM to 2013-04-05 19:10:00PM)  

then we can't able to fine the time difference. So check the code for Question No 1 and give the feedback.  

  

Regards,  

GVPrabu you write an int, but try to receive a c-string, that can not work.

the radio will not be available (i.e. have a packet received) 99.9% of the time,

introducing a delay and printing something if that is the case is just crazy.

so your code seems to be copy and pasted crap without any understandin… ```
#!/usr/bin/perl
use strict; 
use warnings; 

my $gia = '12tai';

#Capture sequence of digits into one variable,
#capture sequence of non-digits into another variable
my ($number, $name) = $gia =~ m/(\d+)(\D+)/;

print "$number $name\n";#Two values separated by one space
``` Hi Shirin\_2,


Just got to see your question you asked on this forum.  

You are welcome to the world of Perl where impossible things are made possible and difficult things made easy :)


As regards your question. It actually a straight forward hash parse with no need for either of the file been compared. The reason is, the all the first column in the first file are all present in the second file. Of course, for the practice of what is it we can still compare but to what end? Except we are going to include our findings in the final compare table. 


All that been said. There are more than one ways to do this. But one of the better way is to use the module *Text::CSV\_XS* instead of spliting on each of the line of the files.


Since you have two files, you can use either a single hash variable or two hash variables, since the keys *must* always be unique you can get all you wanted and then compare to print out desired output.


Here is an one way of doing it....



```
use warnings;
use strict;
use Text::CSV_XS;
use Data::Dumper;
use Inline::Files;

my $hash = {};

my $csv = Text::CSV_XS->new( { binary => 1, sep_char => ';' } );
while ( my $row = $csv->getline(*FILE1) ) {
    push @{ $hash->{ $row->[1] }{ $row->[0] } }, $row->[2];
}

$csv = Text::CSV_XS->new( { binary => 1, sep_char => ';' } );
while ( my $row = $csv->getline(*FILE2) ) {
    push @{ $hash->{ $row->[1] }{ $row->[2] } }, $row->[0];
}

print Dumper($hash);

__FILE1__
CLAYCOUNTY;Wood;statecode=FL
CLAYCOUNTY;Wood;statecode=FL
SUWANNEECOUNTY;Wood;statecode=FL
SUWANNEECOUNTY;Wood;statecode=TX
SUWANNEECOUNTY;Wood;statecode=TX
SUWANNEECOUNTY;Wood;statecode=TX
NASSAUCOUNTY;Wood;statecode=UT
__FILE2__
119736;Residential;CLAYCOUNTY
448094;Residential;CLAYCOUNTY

223488;Residential;CLAYCOUNTY
433512;Residential;CLAYCOUNTY
640802;Residential;SUWANNEECOUNTY
403866;Residential;SUWANNEECOUNTY
828788;Residential;SUWANNEECOUNTY

471817;Residential;NASSAUCOUNTY

```

and my **raw** output will be

                                               ]
                           }
        };
```

From the output, you can see Wood => countryName => {....}, then you can also see Residential => countryName => {......}. Which can then be worked with and desired output gotten.


You might have to open and read these files, I used module *Inline::Files* to achieve that purpose in this program. The comparsion and the output of a desired output is left for the OP as practice. 


Hope this helps. It' just standard c++ ifstream and ofstream. When the program starts, try to open the file, if it success then read it. hi,
thanks that does help tremendously! what you're dealing with is a "wait until ready" timeout condition. in other words test studio timed out waiting for the browser to say "i'm done downloading and rendering all the data for this website". there is a global setting for this which has a default value of just 30 seconds. it is the "client ready timeout" setting as shown in the [last figure on this page](http://www.telerik.com/automated-testing-tools/support/documentation/user-guide/test-execution/quick-execution.aspx) for quick execution. an equivalent setting exists in [the test list settings](http://www.telerik.com/automated-testing-tools/support/documentation/user-guide/test-execution/test-list-settings.aspx) when running your tests as part of a test list..  

  

if you don't want to set it globally (which can make sense to have the timeout much shorter for the remainder of your test) you'll have to resort to performing your navigate step in code... but it's pretty easy. try this:  

  


`int` `oldvalue = manager.settings.clientreadytimeout;`
`manager.settings.clientreadytimeout = 360000;`
`activebrowser.navigateto(``"my website here"``);`
`manager.settings.clientreadytimeout = oldvalue;`
