CRON tidbit
****** message to minivend-users from "Thompson-Jordan" <Thompson-Jordan@mindspring.com> ******
I am sure that you all know everything there is to know about cron and
crontab, but I just learned what the format of those cron files is and
thought I would share it. In the Minivend manual it says:
- Put this in crontab to expire session database
44 4 * * * /home/user/minivend/bin/expireall -r
What that line does is run the Minivend expireall program at 4:44 am each
morning. Why that wasn't clear to me I'll never know :-) Hey Mike? Why
4:44?
The format for lines in your crontab is:
minute hour day month year program
An asterisk mean "do every", so:
44 4 * * * is every day at 4:44
30 12 1 * * is every month on the 1st at 12:30
There are a bunch of other complex and even more cryptic ways to specify
dates and times (after all it is Unix). On my system you type the
following to list your crontab (you may not need "-u username"):
crontab -u username -l
To edit the crontab type the following, which brings up vi:
crontab -u username -e
Good luck.
