Regex to match the given formats-CodePudding

i'm trying to match the below names

abc.cdf.ghi.klm-1.0.0.zip
abc.cdf.ghi.klm_config-1.0.0.18.zip

I have created ^abc.cdf.ghi.klm(-|_config)(\d*).(\d*).(\d*)(.(\d*).zip), but its only matching the first name. How to match the second name

CodePudding user response：

Your current pattern has multiple issues, including not being correct and also not escaping regex metacharacters. Consider this version:

^abc\.cdf\.ghi\.klm(?:_config)?-\d (?:\.\d )*\.zip$

Demo

Explanation:

^                   from the start of the filename
abc\.cdf\.ghi\.klm  match abc.cdf.ghi.klm
(?:_config)?        optionally followed by _config
-                   -
\d                  a number
(?:\.\d )*          optionally followed by dot/number zero or more times
\.zip               ending in .zip
$                   end of the filename
