CLI - Regex with "?"

L1 Bithead

Hello all,

 

Does anybody know how to use a Regex that contains "?", obviously that doesn't work because that automatically triggers the helper?

For example, I'm trying to filter results for a certain CLI command using this:

 

| match (?s)(word1.*?)(?=word2|$)

 

You can see that it contains multiple question marks, I'm not sure what I can do to get those through (if at all possible) and Palo documentation doesn't help.

The regular expression syntax in PAN-OS® is similar to traditional regular expression engines but every engine is unique. The following table describes the syntax supported in PAN-OS.

Description
.
Match any single character.
?
Match the preceding character or expression 0 or 1 time. You must include the general expression inside parentheses.
Example: (abc)?

 

I see that you are not putting the parenthesis around correctly perhaps.. word1.*?  should be (word1.*)?   According the to docs.

Thanks, I did indeed try the suggested parenthesis thing before from the documentation but that didn't help, the "?" was still getting omitted.
