     13 .Sh DESCRIPTION
     14 .Nm
     15 is a simple bandwidth monitor.
     16 .Sh OPTIONS
     17 .Bl -tag -width "-i interface"
     18 .It Fl B
     19 Show values in bytes instead of bits in default output.
     20 .It Fl c Ar count
     21 Stop monitoring after
     22 .Ar count
     23 samples.  If
     24 .Ar count
     25 is 0, it will loop forever.  This is the default.
     26 .It Fl d Ar delay
     27 Sample interface statistics every
     28 .Ar delay
     29 ms.  The default delay is 1000 ms.
     30 .It Fl i Ar interface
     31 Monitor the selected
     32 .Ar interface .
     33 If not provided the first active, non-loopback interface will be used.
     34 .It Fl t
     35 Enable terse output.  The first pair of values is Rx/Tx in bits per second and the
     36 second pair is Rx/Tx in packets per second.
     37 .El
     38 .Sh SIGNALS
     39 If
     40 .Nm sbm
     41 receives a SIGINFO (usually set to ‘^T’) signal (or SIGUSR1 on Linux),
     42 the accumulated amount of data transmitted for Rx and Tx and the time
     43 since the program started will be printed to the standard output.
