Regex Editor & Tester

Matches lines ending with a filename that starts with the literal prefix 'MTN_AFGHANISTAN_RGS30_', followed by any characters, and ends in '.csv'. The multiline flag makes $ anchor to the end of each line, ideal for scanning file listings or logs, while the global flag captures all matches. Typically used in telecom data pipelines or file-watching scripts to filter RGS30 report CSV files from MTN Afghanistan. Note the unescaped dots technically match any character.
