Here is a regular expression to parse file entries from output of the "dir" command on Windows systems: (\d{2}\/\d{2}\/\d{4}\s+\d{2}:\d{2}\s+[AP]M)\s+([\d,]+)\s+(.+) with multiple lines modifier "m": m Note that:

(\d{2}/\d{2}/\d{4}\s+\d{2}:\d{2}\s+[AP]M) - File timestamp
([\d,]+)                                  - File size
(.+)                                      - File name
