NAME
       ifstat - handy utility to read network interface statistics

SYNOPSIS
       ifstat [ OPTIONS ] [ INTERFACE_LIST ]

       INTERFACE_LIST := INTERFACE_LIST | interface

DESCRIPTION
       ifstat  neatly  prints  out  network interface statistics.  The utility
       keeps records of the previous data displayed in history	files  and  by
       default	only  shows  difference between the last and the current call.
       Location of the history files defaults to /tmp/.ifstat.u$UID but may be
       overridden with the IFSTAT_HISTORY environment variable. Similarly, the
       default location for xstat (extended stats) is /tmp/.<xstat  name>_ifs‐
       tat.u$UID.
