pattern matching for string [SYN, ACK]

phemal has asked for the wisdom of the Perl Monks concerning the following question:

Suppose i have string containing both "[SYN]" and "[SYN, ACK]" patterns. can someone help me writing a patern matching for the above.

i tried /\bstring\b/ but both pattern have square brackets and hence not able to find a suitable match.

Are you looking for this? `m/\[SYN(?:, ACK)?\]/` What are you actually trying to accomplish? Dave	[reply] [d/l]

The following pattern may be what you want: `/\[SYN(?:, ACK)?\]/` [download] Update: couple more test strings added DWIM is Perl's answer to Gödel	[reply] [d/l] [select]
