   8 SYNOPSIS
   9 ========
  10 vtysh [ -b ]
  11
  12 vtysh [ -E ] [ -d *daemon* ] [ -c *command* ]
  13
  14 DESCRIPTION
  15 ===========
  16 vtysh is an integrated shell for the FRRouting suite of protocol daemons.
  17
  18 OPTIONS
  19 =======
  20 OPTIONS available for the vtysh command:
  21
  22 .. option:: -b, --boot
  23
  24    Execute boot startup configuration. It makes sense only if integrated config file is in use (not default in FRRouting). See Info file frr for more info.
  25
  26 .. option:: -c, --command command
  27
  28    Specify command to be executed under batch mode. It behaves like -c option in any other shell - command is executed and vtysh exits.
  29
  30    It's useful for gathering info from FRRouting daemons 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.
  31
  32 .. option:: -d, --daemon daemon_name
  33
  34    Specify which daemon to connect to. By default, vtysh attempts to connect to all FRRouting 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.
  35
  36 .. option:: -e, --execute command
  37
  38    Alias for -c. It's here only for compatibility with Zebra routing software and older FRR versions. This will be removed in future.
  39
  40 .. option:: -E, --echo
  41
  42    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.
  43
  44 .. option:: -C, --dryrun
  45
  46    When the -C option is being used, this flag will check the config for syntatic validity.
  47
  48 .. option:: -m, --markfile
  49
  50    Mark the input file with context ends, useful for cleanup of a config file that has a lot of extraneous space and end markers
  51
  52 .. option:: -n, --noerror
  53
  54    When executing cli that does not invoke a vtysh shell, if an error ocurrs ignore it for purposes of return codes from vtysh.
  55
  56 .. option:: -u, --user
  57
  58    Restrict access to configuration commands by preventing use of the "enable" command. This option provides the same limited "security" as password-protected telnet access. *This security should not be relied on in production environments.*
  59
  60    Caveat emptor: VTYSH was never designed to be a privilege broker and is not built using secure coding practices. No guarantees of security are provided for this option and under no circumstances should this option be used to provide any semblance of secure read-only access to FRR.
  61
  62 .. option:: -h, --help
  63
  64    Display a usage message on standard output and exit.
  65
  66 ENVIRONMENT VARIABLES
  67 =====================
