Keeping Track

3.4 Setting up periodic jobs

Allow the new user gnats access to cron and at. To do this, add the name gnats to the files `cron.allow' and `at.allow', which normally reside in the directory `/var/spool/cron'. If these files do not exist, make sure gnats does not appear in either of the files `cron.deny' and `at.deny' (in the same directory). If you changed the name of the GNATS user during configure, remember to substitute as appropriate in the previous steps.

Create a crontab entry that periodically runs the program queue-pr with the `--run' option (see section queue-pr). For example, to run `queue-pr --run' every ten minutes, create a file called `.mycron' in the home directory of the user gnats which contains the line:

0,10,20,30,40,50 * * * * exec-prefix/libexec/gnats/queue-pr --run

(Specify the full path name for queue-pr.) Then run

crontab .mycron

See the man pages for cron and crontab for details on using cron.
