NAME

   vtysh - a integrated shell for Quagga routing software

SYNOPSIS

   vtysh [ -b ]
   vtysh [ -E ] [ -d daemon ] ] [ -c command ]

DESCRIPTION

   vtysh is a integrated shell for Quagga routing engine.

OPTIONS

   Options available for the vtysh command:

   -b, --boot
          Execute  boot  startup  configuration.  It  makes  sense only if
          integrated config file is in use (not default  in  Quagga).  See
          Info file Quagga for more info.

   -c, --command command
          Specify command to be executed under batch mode. It behaves like
          -c option in any other shell - command  is  executed  and  vtysh
          exits.

          It's  useful  for gathering info from Quagga routing software or
          reconfiguring daemons from inside shell scripts, etc.  Note that
          multiple  commands  may  be  executed  by using more than one -c
          option and/or embedding linefeed characters inside  the  command
          string.

   -d, --daemon daemon_name
          Specify  which daemon to connect to.  By default, vtysh attempts
          to connect to all Quagga daemons running on  the  system.   With
          this  flag,  one  can  specify  a  single  daemon  to connect to
          instead.  For example, specifying '-d ospfd' will  connect  only
          to  ospfd.   This can be particularly useful inside scripts with
          -c where the command is targeted for a single daemon.

   -e, --execute command
          Alias for -c.  It's  here  only  for  compatibility  with  Zebra
          routing software and older Quagga versions. This will be removed
          in future.

   -E, --echo
          When the -c option is being  used,  this  flag  will  cause  the
          standard  vtysh  prompt  and  command  to  be  echoed  prior  to
          displaying the results.  This is particularly useful to separate
          the results when executing multiple commands.

   -h, --help
          Display a usage message on standard output and exit.

ENVIRONMENT VARIABLES

   VTYSH_PAGER
          This should be the name of the pager to use. Default is more.

FILES

   /usr/local/etc/vtysh.conf
          The default location of the vtysh config file.

   /usr/local/etc/Quagga.conf
          The  default  location  of  the integrated Quagga routing engine
          config file if integrated config file is in use (not default).

   ${HOME}/.history_quagga
          Location of history of commands entered via cli
