Regex Tester & Validator

This PCRE regex uses lookahead and lookbehind assertions to split a string, likely a file path, around variations of the word "administrator". The first capture group matches everything occurring before the word "administrator", while the second capture group extracts everything following an occurrence of "administrator" that is immediately succeeded by a digit. It is specifically useful for parsing logs or bash paths where directories or filenames contain this dynamic naming convention.
