So here are some tips. - In general, do not edit the system crontab files, instead edit your user crontab files with 'crontab -e' where '-e' means edit. You will need an environment variable to setup an editor like this: 'export EDITOR=nedit'. You can put the whole path to nedit in there if need be. So, what is the exact command you are using to edit the crontab files? - When the cron job runs it runs in it's own shell, with no environment variables at all, i.e. no PATH or anything. To set environment variables add these entries to the crontab file: PATH=/usr/bin:/sbin:/whatever MAIL=youruser (sends email to this account) Each time cron runs and produces output, an email is sent to the account in the MAIL variable. - Next, the command must include the full path to the command like this: 1 18 29 1 * /home/comp/perl/me/gocron If gocron is a bash script which calls a Perl program, I always pass the working directory to my Perl program inside the 'gocron' bash script. I think I had trouble getting the current directory inside my Perl script with $t=`pwd`;. It would work during testing outside of cron, but when it was run by cron, pwd didn't work. I also test my bash scripts with the 'at' command, which works very much like cron, but with less typing. The at format is: at -f FILETORUN TIMESPEC Example: at -f /path/to/file/gocron now (run now) Example: at -f /path/to/file/gocron + 1 minute (run 1 minute from now) Example: at -f /path/to/file/gocron 2:05pm (runs at 2:05pm based on the server time) This runs my gocron bash script after 1 minute passes. See the man page for 'at' for more info on the TIMESPEC format.
