NAME
knife-ssh - Run a command or interactive session on multiple remote hosts

SYNOPSIS
knife ssh QUERY COMMAND (options)

-a, --attribute ATTR
    The attribute to use for opening the connection - default is fqdn

-C, --concurrency NUM
    The number of concurrent connections

-m, --manual-list
    QUERY is a space separated list of servers

-P, --ssh-password PASSWORD
    The ssh password

-x, --ssh-user USERNAME
    The ssh username

--[no-]host-key-verify

DESCRIPTION
The ssh sub-command opens an ssh session to each of the nodes in the search results of the QUERY. This sub-command requires that the net-ssh-multi and highline Ruby libraries are installed. On Debian systems, these are the libnet-ssh-multi-ruby and libhighline-ruby packages. They can also be installed as RubyGems (net-ssh-multi and highline, respectively).

TERMINAL MULTIPLEXING AND TERMINAL TAB SUPPORT
knife ssh integrates with several terminal multiplexer programs to provide a more convenient means of managing multiple ssh sessions. When the COMMAND option matches one of these, knife ssh will create multiple interactive ssh sessions running locally in the terminal multiplexer instead of invoking the command on the remote host.

The available multiplexers are:

interactive
    A built-in multiplexer. interactive supports running commands on a subset of the connected hosts in parallel

screen(1)
    Runs ssh interactively inside screen. ~/.screenrc will be sourced if it exists.

tmux(1)
    Runs ssh interactively inside tmux.

macterm (Mac OS X only)
    Opens a Terminal.app window and creates a tab for each ssh session. You must install the rb-appscript gem before you can use this option.
