 *-l* 'filename'::
     This option writes the output messages to a log file instead of standard output.
 
+*--verbose* 'level'::
+     Set the log level. Supported log levels are "none", "critical", "error", "warning",
+     "info", "debug", "all" or their identifiers "0", "1", "2", "3", "4", "5", "6". Setting the log
+     level to specific value enables all logs from that and all previous levels.

+     Example: enable all critical, error and warning logs

+      trace-cmd listen --verbose warning
