#       -p, --priority=
#           Filter output by message priorities or priority ranges. Takes
#           either a single numeric or textual log level (i.e. between
#           0/"emerg" and 7/"debug"), or a range of numeric/text log levels in
#           the form FROM..TO. The log levels are the usual syslog log levels
#           as documented in syslog(3), i.e.  "emerg" (0), "alert" (1),
#           "crit" (2), "err" (3), "warning" (4), "notice" (5), "info" (6),
#           "debug" (7). If a single log level is specified, all messages with
#           this log level or a lower (hence more important) log level are
#           shown. If a range is specified, all messages within the range are
#           shown, including both the start and the end value of the range.
#           This will add "PRIORITY=" matches for the specified priorities.
