       nload - displays the current network usage

       nload is a console application which monitors network traffic and bandwidth usage in  real
       time.  It visualizes the in- and outgoing traffic using two graphs and provides additional
       info like the total amount of transferred data and min/max network usage.


       When running nload, you can switch between the devices (which you gave nload either on the
       command  line  or  which were auto-detected) by pressing the left and right arrow keys. If
       the -m command line parameter is given, the arrow keys switch as  many  devices  back  and
       forth  as  there  are  shown  on the screen. If you want to quit, do so by pressing 'q' or

       For further key shortcuts, have a look at the  sections  MAIN  WINDOW  and  OPTION  WINDOW


       A summary of the options supported by nload is included below.

       -a period
              Sets the length in seconds of the time window for average calculation.  The default
              is 300.

       -i max_scaling
              Specifies the 100% mark in kBit/s of the graph indicating  the  incoming  bandwidth
              usage.   Ignored  if  max_scaling is 0 or the switch -m is given. The default value
              for max_scaling is 10240.

       -m     Show multiple devices at a time; do not show the traffic graphs.

       -o max_scaling
              Same as -i but for the graph indicating the outgoing bandwidth usage.

       -t interval
              Determines the refresh interval of the display in milliseconds.  The default  value
              of interval is 500.

              PLEASE NOTE: Specifying refresh intervals shorter than about 100 milliseconds makes
              traffic calculation very unprecise. Also the display may flicker using  such  short
              refresh   intervals.   nload  tries  to  balance  this  out  by  doing  extra  time
              measurements, but this may not always succeed.

       -u h|H|b|B|k|K|m|M|g|G
              Sets the type of unit used for the display  of  traffic  numbers.   h  means  human
              readable  (auto), b Bit/s, k kBit/s, m MBit/s and g GBit/s.  The upper case letters
              mean the corresponding units in Bytes (instead of Bits).  The default is k.

       -U h|H|b|B|k|K|m|M|g|G
              Same as -u, but for an amount of data, e.g. Bit, kByte, GBit etc.  (without  "/s").
              The default is M.

              Network  devices  to  use.  The  default is "all", which means to display all auto-
              detected devices.

       -h, --help
              Show a short summary of these command line options.


       After starting, nload begins to monitor the network devices given on the command line, or,
       if none where specified, the default device. In this mode, the following key shortcuts are

       'ArrowRight', 'ArrowDown', 'PageDown', 'Enter', 'Tab'
              Switch the display to the next network device, or, when started with the  -m  flag,
              to the next page of devices.

       'ArrowLeft', 'ArrowUp', 'PageUp'
              Switch  the  display  to  the previous network device, or, when started with the -m
              flag, to the previous page of devices.

       'F2'   Show the option window (see section OPTION WINDOW below).

       'F5'   Save current settings to the user's config file.

       'F6'   Reload settings from the config files.

       'q', 'Ctrl+C'
              Quit nload.


       The parameters given to nload on the command line can  be  adjusted  during  run  time  by
       pressing  the  'F2'  key.  A  small  window  appears on the top of the screen, listing the
       available settings.

       'F2'   Show/hide the option window.

       'ArrowLeft', 'ArrowRight', 'Home', 'End'
              Navigate within the edit fields.

       'ArrowUp', 'ArrowDown', 'Enter'
              Navigate between the settings.

       'PageUp', 'PageDown', 'Tab'
              Toggle between the different values possible for the current field.

       '+' / '-'
              Switch to the next / previous page of settings.


              System-wide configuration file.

              User-specific configuration file (overrides system-wide settings).

       /sys/class/net/*/* /proc/net/dev
              are read by nload when running on Linux to get the network traffic data.
