I'd like
to write a simple script that alerts me if a log changes. For this I'm using grep
to find the lines I'm interested in. Right now it works like this:
grep line /var/log/file | mail -s Log
[email protected]
Problem is that this sends a mail even if no matching lines are found. The mail utility from mailutils seems
to have no switch telling it
to drop mails that have an empty body.
Is there a
quick and easy way
to do so?
