Stopping cron job
Hi,

I have scheduled one job in crontab. I want to stop the job automatically after some time of its execution without killing it.

Could i archive the above?

On some operating systems you can send a SIGSTOP signal to a process to suspend it, and a SIGCONT signal to have it resume processing. But, if a process was processing network connections when it is suspended, the connections may timeout while it is suspended and might not be recoverable when it resumes.

I don't know what you mean when you say you want to archive a stopped process???

Can you clarify what you mean by "stop the job automatically after some time of its execution without killing it". Can I interpret that as you want to suspend (sleep) the execution of the job under certain conditions? If so, what are those conditions?

Might you even be asking "I want this to run for 3 months and then not after that." or something similar?

If so, you could set yourself an at job to:-
  • Get your cron-table definition
  • Comment out the line you want to suspend
  • Re-submit the for future (non) running

I regret that you have not been clear enough on what you actually want for anyone to be though.

@rbatte1......AFAIK if you comment out a crontab line directly, depending on the O/S, it might not see that change for up to 24 hrs. That can happen because you by-pass the proper crontab tools for inserting/deleting jobs. To ensure immediate effect the script would need to stop/restart the cron daemon, and to do that, it would need to be running as root.

No need to do so directly. The proper crontab tool responds to scripting.
