Shell Programming and Scripting

Hi Guys

Please help me with a script. I don't have any idea on scripting.

When /var usage goes to 90%, I want the file /var/log/tsm/dsmsched.log to be nulled.

The command to null is

Code:

cat /dev/null > /var/log/tsm/dsmsched.log

but how to make it happen when /var usage is at 90%

Code:

 >/var/log/tsm/dsmsched.log

does the job too...

Completing Ravinders post, the choice of how will depend what utilites you have running to monitor...
If none, then you are to write a script and use cron...

Hi,

I'm guessing that you have a log that is filling /var here and that you suspect that the culprit is;

Code:

/var/log/tsm/dsmsched.log

The proper way to address this problem is to modify the configuration file;

Code:

dsm.sys

You should read the proper documentation when you are looking to correct issues with applications like TSM, you can find specific information here.
