Question Null a file when /var usage is at 90%
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%
