Most modern Linuxes also have a facility to all files in a directory.  These Linux versions will usually preload your crontab to run at a different directory every hour, day, week, or month.  Usually, these directories are called /etc/cron.daily for the once per day, etc.

If your system is so equipped, simply placing a running script, with execute permissions on the appropriate folder, will cause the script to be added to the rotation.  If its important, be aware that run-parts runs files alphabetically.

Once the file is put in one of these directories, cron will automatically find it, no need to mess with a crontab file at all, and since run-parts is executed from the system crontab, everything is run as root.

Hi,

I have been setting up a cron job and found out there are two different crons. 1) the user cron located at  /var/spool/cron/ on my Fedora Box and 2) the system crontab located at /etc/crontab .

When I do the crontab -e (if I am recalling correctly) I am editing the user crontab.  


To edit the system crontab do I just use VI or some other editor?

I would have thought if I were root and issued crontab -e I would have been editing the system crontab, however this was not my experience.


Thanks in advance for your insight.
