Crontab question

ctcuser · #1 (**permalink**) 10-19-2006

Hello,
Does anybody know of a way to add an entry to the crontab without executing >crontab -e? I'm running a script that would add a line without any user intervention. The only way I could think of would to use sed to add the line to the end of the cron file, but I don't know if this would cause problems. Would it?
OS - aix 5.3

thanks,

OK, will the following sequence of commands work or will it cause problems? I found this after I posted my question.
crontab -l > mycrontab
#add a line via sed command to mycrontab
crontab < mycrontab

thanks,

Yes, something similar to that should be fine.

Code:

crontab -l > crontab.tmp
# [manipulate contab.tmp]
crontab crontab.tmp
rm crontab.tmp # if you want to delete the .tmp file
