Is there a better way to clean the log file? I usually delete the old logfile and create a new logfile and I am looking for a shorter type/bash/command program. How can I use an alias?
How to clean log file?
logs
> logfileorcat /dev/null > logfileif you want to be more eloquent, will empty logfile (actually they will truncate it to zero size). If you want to know how long it takes, you may usedd if=/dev/null of=logfile(which is the same as dd if=/dev/null > logfile, by the way)You can also usetruncate logfile --size 0to be perfectly explicit or, if you don't want to, rm logfile(applications usually do recreate a logfile if it doesn't exist already).However, since logfiles are usually useful, you might want to compress and save a copy. While you could do that with your own script, it is a good idea to at least try using an existing working solution, in this case logrotate, which can do exactly that and is reasonably configurable.
