Question

I have a log file where summary will have 0 Error(s) or X Error(s).

I tried to find Errors other than 0 Error(s).

I tried with this option in Regular expression but it does no good. \ [^0] Error(s)

Am I missing anything else?

Answer 1

Try this here

 [1-9][0-9]* Error\(s\)

You don’t need to escape spaces, but you need to escape brackets, if you want to match them literally. And be careful with [^0], it will match anything but a 0 (e.g. akÖ{@), not only other digits.

This expression will also match numbers with more than one digit.
