tmux split-window
Create a new pane by splitting target-pane: -h does a horizontal split and -v a vertical split; if neither is specified, -v is assumed.
Syntax¶
tmux split-window [-bdefhIPvZ] [-c start-directory] [-e environment] [-F format] [-l size] [-t target-pane] [command]Alias: splitw.
Behavior¶
-h does a horizontal split and
-v a vertical split; if neither is specified,
-v is assumed. The -l
option specifies the size of the new pane in lines (for vertical split) or
in columns (for horizontal split); size may be
followed by ‘%’ to specify a
percentage of the available space. The -b option
causes the new pane to be created to the left of or above
target-pane. The -f option
creates a new pane spanning the full window height (with
-h) or full window width (with
-v), instead of splitting the active pane.
-Z zooms if the window is not zoomed, or keeps it
zoomed if already zoomed.
An empty shell-command ('') will create
a pane with no command running in it. Output can be sent to such a pane
with the display-message command. The
-I flag (if shell-command
is not specified or empty) will create an empty pane and forward any
output from stdin to it. For example:
$ make 2>&1|tmux splitw -dI &All other options have the same meaning as for the
new-window command.
