Regex Tester & Validator

This regex matches lines that begin with the keyword 'CIMTS', followed by a business description (word characters and spaces), a date in DD/MM/YYYY format, and a final designator code of DL, DL2, D, or L. It is useful for extracting structured business situation entries from log files or reports where each record includes a code, description, date, and a type flag. The multiline flag (gm) allows matching across multiple lines and ensures the pattern anchors properly at each line start.
