usage: crontab [-u user] file
crontab [-u user] { -e | -l | -r }
(default operation is replace, per 1003.2)
-e (edit user's crontab)
-l (list user's crontab)
-r (delete user's crontab)
I use always joe because I'm too stupid to learn the VI:
$ export EDITOR=joe
you may use also `vim' as editor.
Then run:
$ crontab -e
In joe I get existing crontabs and if there are none then
an empty file, first line in my files is always:
MAILTO=gp at familiehaase.de # <---- your.real@adress.here
and then the jobs:
0 0-23/4 * * * /usr/bin/updatedb
This means:
Run: /usr/bin/updatedb at 0:00, 4:00, 8:00, 12:00, 16:00, 20:00 o'clock,
every day of the month (say every four hours).
For details how to run a job every Monday to Friday but not Saturday and
Sunday look `man crontab' & `man 5 crontab' & `man cron'
The daemon itself is installed with cygrunsrv, see in the archives:
