In fact as your schedule file is copied to /var/spool/cron it is given the username as its file name. You must be root to see the contents of /var/spool/cron. crontab -l will list the contents of your currently active schedule file. crontab -e allows you to edit the currently active schedule file but I prefer to edit my original schedule file and resubmit it so I always have a copy of it. In fact I may have multiple schedule files in my home directory for various purposes. See man page crontab(5) for details and examples of what the schedule file contents should look like. The crontab lines may contain an actual command or reference a shell script or other program. Create you schedule file using any text editor. Then put it into the crond queue using crontab. crontab does some syntax checking of your file at this time. crond wakes up every minute to see if there is any work for it to start. When it does it will find your schedule file and processes the entries in it, starting jobs at the specified times. see also crontab(1) and crond(8) -- Paul Almquist paul@xxxxxxxxxxxxx Eau Claire, WI USA
