tmux new-window

tmux new-window [-abdkPS] [-c start-directory] [-e environment] [-F format] [-n window-name] [-t target-window] [shell-command [argument ...]]

Create a new window. With -a or -b, the new window is inserted at the next index after or before the specified target-window, moving windows up if necessary; otherwise target-window is the new window location.

If -d is given, the session does not make the new window the current window. target-window represents the window to be created; if the target already exists an error is shown, unless the -k flag is used, in which case it is destroyed. If -S is given and a window named window-name already exists, it is selected (unless -d is also given in which case the command does nothing).

shell-command is the command to execute. If shell-command is not specified, the value of the default-command option is used. -c specifies the working directory in which the new window is created.

When the shell command completes, the window closes. See the remain-on-exit option to change this behaviour.

-e takes the form ‘VARIABLE=value’ and sets an environment variable for the newly created window; it may be specified multiple times.

The TERM environment variable must be set to ‘screen’ or ‘tmux’ for all programs running inside tmux. New windows will automatically have ‘TERM=screen’ added to their environment, but care must be taken not to reset this in shell startup files or by the -e option.

The -P option prints information about the new window after it has been created. By default, it uses the format ‘#{session_name}:#{window_index}’ but a different format may be specified with -F.
