Pipe a command and using match regular expressions

[epacke]

Dear experts!

I'm trying to compile a match which matches the following regexp: (debug|monitor).(global|level|pcap|detail\.enable) but it seems like it does not support capturing groups. I've searched for a manual for the match command but struck out. 

The end game here is to use it to filter show system state to capture lines containing:

• debug.global
• debug.level
• debug.pcap
• monitor.detail.enable

Looks like capture lists is supported, ie. show system state | match debug.[glp] but capturing groups is what I need.

Does anyone here have a solution or tip?

Kind regards,

Patrik

Looks like you were already pretty close, you needed to escape the pipe. This seems to work for me:

show system state | match debug.[glp]\|monitor.detail.enable

More broadly, you could probably use although it gets a bit unwieldy after enough entries.

show system state | match debug.g\|debug.l\|debug.p\|monitor.detail.e

Good luck!

Thank you so much Greg.

They really need to improve their documentation in this part. And I need to improve my brain.

Can't believe I did not try that. 🙂

Thanks Greg! Huge help for us.

This is great, backwards, but great (one should escape control characters if they want to include them in the match, not the other way 'round). Thank you!
