Hi t-rex,

A single example input is not a good basis for making a regular expression, you'll need to show several examples of strings that should match and several that shouldn't, and also describe what specific information in the string you're interested in. For example, the regexes /TPSM/ and /rulefilecycl/ both match the string you provided, but I have no idea if those will also match lines you don't want to have matched.

Also, PerlMonks is more of a place to learn, so I recommend you have a look at perlretut and try writing a regex, and feel free to ask for help here if you run into trouble (How do I post a question effectively?). The following website is also very helpful in designing a regex, here's a link to get you started: https://regex101.com/r/oX5sC6 (note that not all of Perl's features are supported, but for simple regexes like in this case it's compatible).

Hope this helps,
-- Hauke D
