Just add a line to /etc/crontab as root. Search Google for what each of the fields in this file mean, and use the existing lines as a template.

You will want something like:

Code:

0 2 * * 0 "squidguard -C all"

Which will run the command every Sunday at 2am.

If this is not what you were after, can you give us more info.

Just insert into /etc/crontab using crontab -e command.

http://www.tech-geeks.org/contrib/md...ntab-howto.htm
... above is a howto for using cron and crontab.

Something like:

0 2 * * 0 /path/to/SquidGuard -C all

should run squidguard at 2am every sunday.
(you may want this in the root users crontab though)

Whose crontab are you editing? Yours or root's?
Who does the program SquidGuard belong to (ls -l SquidGuard)
Post the exact line you are using in the crontab that you say is not working

billymayday · 04-09-2007, 05:44 AM

You shouldn't need the quotes in the crontab line. Try

0-59/1 * * * * /path/to/squidGuard -C all

Simon Bridge · 04-09-2007, 06:07 AM

Please read the howto in my last post.

More information is needed if anyone is to help you.

hi all
in my crontab file only this command is present

0-59/1 * * * * "/usr/local/squidGuard/squidGuard -C all"

but this not work

IBall · 04-10-2007, 01:30 AM

We really need more information from you to help. "Here is the line, it doesn't work" doesn't tell us anything.

What happens if you try to run "squidGuard -C all" manually as root (ie not through crontab)?

Have you looked at the howto that was linked above? What parts of it do you not understand?

Check roots mailbox - cron by default will email the output of the command to root.

Also, if you want to run the command every minute, just replace the 0-59/1 bit with a * like in the other fields. * means every minute.

Did you use crontab -e to edit /etc/crontab?

I notice that you have failed to follow advise that was given you and failed to provide details asked for. The question before us now is: why should we help you?

1) Read the howto linked by Simon Bridge in post #3.

2) Answer the questions in my above post. In particular, does the command work if you run it manually. Do you get any messages in root's mail to give you the output of the above comand? You must answer these questions if we are to help you further.

3) Any scripts placed in /etc/cron.daily will be run once per day at the time specified in /etc/crontab. Likewise, scripts in /etc/cron.weekly are run once per week at the time specified in /etc/crontab.
