Linux log parser in Bash

Greetings all.

Working on a requirement to parse a (text) log on a Red Hat Linux VM.

The Solarwinds built-in log parser come to us written in Perl. For me Perl is a black box. I like Bash.

Does anyone know of a Linux log parser in Bash that will work with Solarwinds? I am especially interested in the "new strings found" functionality.

Btw specifically I want to make custom labels for the return variables to Solarwinds. Out of the box it's like "Message:Message" "Message:Statistic". Trying to make it like "Message.my_target_return_string:$returnstring", "Statistic.my_target_return_string:$returnstat" . If someone can detail how to do this with the out-of-box Perl log parser that will work fine.

Thanks in advance for any responses from the community.

Dont take this as a sarcastic respond, but chatgpt is awesome at bash. It can probably solve this for you 10 seconds flat

Based on my domain knowledge that chatgpt might not have, everything after the . needs to be predicable. If you create a new string for that on the fly SW wont accept it. You have to preview the outputs and save that script in order for SW to accept custom script outputs.

Probably the easiest thing will be to roll your own. Something like:

This is just a base to start with... since there is no error checking, mine is just returning 0 because of an access denied error.

Putting the regex on the command line would be nice, but you run into difficulties with special characters.

Writing Bash scripts with GPT? What an idea. I'll have to try it.
