On my Debian 2.2 system the system does an operation every 5 minutes.
On xconsole it looks like that:

Nov 28 22:00:01 tarnica /USR/SBIN/CRON[480]: (root) CMD (/usr/lib/atrun 1> /dev/null 2> /dev/null)

What is this, and how can I stop the system from doing that.

Why do you want to stop this?

"cron" is the facility that runs periodic processes.  
"at" is the facility that runs particular jobs at specified times.

OK, where can I change the frequency of this operation?
I don't want Linux accessing my HDD every 5 minutes...

And I even don't have an /usr/lib/atrun file on my system.

(Wait, there is no Debian 2.2 yet ...)

Hmm, then perhaps you have no "at" functionality (although that I think
that atrun should be in /usr/sbin on Debian).  Anyway, you should find the
appropriate cron (config) file and edit out that line.  See the man pages
for crontab(1), crontab(5), and cron(8) to learn all about the subject.

I mean Patato, with 2.2 kernel.

I looked at /etc/crontab, all files in /etc/cron.d/
and I haven't found anuything that could run something every 5 minutes.

Now I installed the at package, and I have /usr/sbin/atrun.
But that doesn't change the problem anyway.

1. HELP: 2>&1 > /dev/null != 2>&- > /dev/null ???

In /bin/sh, I tried to redirect the standard error and standard output to
/dev/null.

I still has the error message from the following command:

        ls /xyz 2>&1 > /dev/null

but not from the following command:

        ls /xyz 2>&- > /dev/null

I thought >&1 is the same as >&-. Any comments are appreciated.

Thank you.

Larry
