hi

I'm looking for a perl or bash script to send a mail if /var partition is 90% full.

Can you send mail from the command line? If not, that will have to be set up before a bash script can work (perl scripts can include a SMTP server module so need not).

Once that is working it is relatively simple to write a bash script to detect when the file system containing /var is used more than 90% and, when it is, to send an email.

I have postfix installed and I can send a mail from the command line:

Code:

echo "Message" | mailx -s "test mail" address@mydomain.net

but I need a bash code for the rest.

Nagios is a great open-source framework for doing all sorts of infrastructure monitoring tasks like this.

If you need a script, you need to write one. We're not going to write your scripts for you, but will be happy to HELP when you're stuck. Since there are MANY thousands of examples you can easily find on Google, you've got a starting point there.

And, once again ... nagios!

Basically, this requirement boils down to ... "infrastructure monitoring." Which is a big, broad class of problems that everyone faces. You will indeed find that this battle-tested tool does a lot of wonderful things.

Shell script to watch the disk space may help.
