Regex Editor & Tester

Matches syslog-style log entries, capturing four groups: a timestamp (e.g., 'Jan 15 14:23:45'), a hostname or source identifier, a process name with optional PID in brackets, and the full log message. Useful for parsing and extracting structured data from standard syslog format logs on Unix/Linux systems. The global and multiline flags allow processing multiple log lines at once.
