how to run (whereis) ulimit in crontab ?
 

Hi,

I am trying to run ulimit from crontab but I could not find where is ulimit located - whereis ulimit did not find anything.

Could please anybody help where is it or how to properly put it in crontab if it is some built-in command (where) ?

thank you,
kind regards,
M.

ulimit is usually a shell builtin, not a binary

Have your cron job call a shell script that includes your ulimit and other commands

yes.

Can anybody please help to beginner how to solve it ?

crontab:
* * * * * /media/DATA/home/u1/bin/crontab/crontab-exec-script.sh /media/DATA/home/u1/bin/crontab/process-manager.sh all >> /var/log/_c-ROOT--process-manager.log 2>&1

crontab-exec-script.sh contains:
sh -c "/bin/bash; ulimit -t 1;'$shellscript'" # $shellscript is "/.../process-manager.sh" in this case

but I have got error:
/media/DATA/home/u1/bin/crontab/crontab-exec-script.sh: line 71: sh -c "/bin/bash; ulimit -t 1;/media/DATA/home/u1/bin/crontab/process-manager.sh": No such file or directory

"no such file or directory" message launched up because ulimit is builtin bash command. (without 'ulimit' it works properly.)


How 'sh -c "/bin/bash; ulimit -t 1;$shellscript" ' should look like ?


thank you very much for any clue,
kind regards,
Martin
