Some notes on cronjobs

While the detailed workings of cron jobs on all potential SSW machines systems is way beyond the scope of this document, we will share some suggestions here. There are machine, OS, and SHELL differences in cron & cronjob behavior - please consider these options as guidelines which may work directly out of the box on many machines, but perhaps not on yours. If none of the suggested options works for you, you might consult a local system expert. If you eventually get something running, please let me know - we can add your comments or new options for the benefit of other SSW users who have simular systems.

How to display, add, or change crontab contents

These commands apply to most UNIX systems.

   % crontab -l                  # list current crontab file (might be empty)
   % crontab -e                  # edit crontab file for current account

Known exceptions:

Ultrix All cronjobs are kept in a single crontab file /etc/crontab. You must explicitly list (ls) or edit that file to add or specific lines.
