Re^2: How to use REGEX Match Variable from one 'While' String in Another 'While' String

Ah! Much easier than I was expecting. Thank you very much for the help! Seems like removing the $line_in did the trick. The regex match only had alphanumeric characters and underscores, so special characters wasn't an issue.

I also removed the extra open and close of the file. Thank you for the suggestion! I really appreciate you taking the time to respond.

The regex match only had alphanumeric characters and underscores... If your `$pkt_file` doesn't contain regular expressions, it's probably better to use `\Q$pkt\E`, because that'll prevent your program from doing unexpected things if `$pkt` does someday for whatever reason contain special characters. Similar to what AnomalousMonk wrote below about `$1 $2 $3` etc. it's a "future-proofing" measure.	[reply] [d/l] [select]
