from my crontab:
-----------------------------
# mail exchange
26 3 * * * ppp-on
27 3 * * * sitecopy -u supine
27 3 * * * sitecopy -u tle
27 3 * * * fetchmail -f /root/.fetchmailrc2
27 3 * * * fetchmail
33 3 * * * ppp-off
----------------------------
this basically ensures that at least once a day my box dials the internet
at just before 3:30am and checks my mail from both my current account
(fetchmail without arguements) and an old one (fetchmail with rc filed
specified) and syncs my two websites...
reading that first line
26 3 * * * ppp-on
^ ^ ^ ^ ^ ^
command to run
every day (day of week - ie 0 is sunday)
every month
every day (day of month - ie 25th)
3 am
26 minutes past the hour
have a read of both
man crontab
and
man 5 crontab
later
