Name

       kitten-@-new-window - Open new window

Usage

       kitten @ new-window  [CMD ...]

Description

       DEPRECATED: Use the launch command instead.

       Open  a  new  window  in the specified tab. If you use the --match option the first matching tab is used.
       Otherwise the currently active tab is used. Prints  out  the  id  of  the  newly  opened  window  (unless
       --no-response  is used). Any command line arguments are assumed to be the command line used to run in the
       new window, if none are provided, the default shell is run. For example::

           kitten @ new-window --title Email mutt

Options

       --match, -m
              The tab to match. Match specifications are of the form: field:query. Where field can  be  one  of:
              id,  index, title, window_id, window_title, pid, cwd, cmdline env, var, state, session and recent.
              query is the expression to match. Expressions can be either a number or a regular expression,  and
              can be combined using Boolean operators.

              The special value all matches all tabs.

              For  numeric  fields:  id,  index,  window_id,  pid and recent, the expression is interpreted as a
              number, not a regular expression. Negative values for  id/window_id  match  from  the  highest  id
              number down, in particular, -1 is the most recently created tab/window.

              When  using title or id, first a matching tab is looked for, and if not found a matching window is
              looked for, and the tab for that window is used.

              You can also use window_id and window_title to match the tab that contains  the  window  with  the
              specified id or title.

              The index number is used to match the nth tab in the currently active OS window. The recent number
              matches  recently  active  tabs  in  the currently active OS window, with zero being the currently
              active tab, one the previously active tab and so on.

              The field session matches tabs that were created in the specified session. Use the  expression  ^$
              to  match  windows  that were not created in a session and . to match the currently active session
              and ~ to match either the currently active sesison or the last active session when no  session  is
              active.

              When  using  the env field to match on environment variables, you can specify only the environment
              variable name or a name and value, for example, env:MY_ENV_VAR=2. Tabs containing any window  with
              the specified environment variables are matched. Similarly, var matches tabs containing any window
              with the specified user variable.

              The  field  state  matches  on  the  state  of  the  tab.  Supported  states are: active, focused,
              needs_attention, parent_active, parent_focused and focused_os_window. Active  tabs  are  the  tabs
              that  are  active  in  their  parent OS window. There is only one focused tab and it is the tab to
              which keyboard events are delivered. If no tab is focused, the last focused tab  is  matched.  The
              value focused_os_window matches all tabs in the currently focused OS window.

              Note that you can use the kitten @ ls command to get a list of tabs.

       --title
              The title for the new window. By default it will use the title set by the program running in it.

       --cwd  The  initial  working directory for the new window. Defaults to whatever the working directory for
              the kitty process you are talking to is.

       --dont-take-focus, --keep-focus [=no]
              Keep the current window focused instead of switching to the newly opened window.

       --window-type [=kitty]
              What kind of window to open. A kitty window or a top-level OS window.

              Choices: kitty, os

       --new-tab [=no]
              Open a new tab.

       --tab-title
              Set the title of the tab, when open a new tab.

       --no-response [=no]
              Don't wait for a response giving the id of the newly opened window. Note that  using  this  option
              means  that  you  will  not  be notified of failures and that the id of the new window will not be
              printed out.

       --help, -h [=no]
              Show help for this command

Global options

       --to   An address for the kitty instance to control. Corresponds  to  the  address  given  to  the  kitty
              instance  via the --listen-on option or the listen_on setting in kitty.conf. If not specified, the
              environment variable KITTY_LISTEN_ON is checked. If that is also not found, messages are  sent  to
              the  controlling terminal for this process, i.e. they will only work if this process is run within
              a kitty window.

       --password
              A password to use when contacting kitty. This will cause kitty to ask the user for  permission  to
              perform the specified action, unless the password has been accepted before or is pre-configured in
              kitty.conf. To use a blank password specify --use-password as always.

       --password-file [=rc-pass]
              A  file  from  which  to  read  the  password.  Trailing whitespace is ignored. Relative paths are
              resolved from the kitty configuration directory. Use - to read from STDIN. Use fd:num to read from
              the file descriptor num. Used if no --password is supplied. Defaults to checking for  the  rc-pass
              file in the kitty configuration directory.

       --password-env [=KITTY_RC_PASSWORD]
              The  name  of  an  environment  variable  to read the password from. Used if no --password-file is
              supplied. Defaults to checking the environment variable KITTY_RC_PASSWORD.

       --use-password [=if-available]
              If no password is available, kitty will usually just send the remote  control  command  without  a
              password. This option can be used to force it to always or never use the supplied password. If set
              to always and no password is provided, the blank password is used.

              Choices: if-available, always, never
