kitty - The fast, feature rich terminal emulator
kitty [options] [program-to-run ...]
Run the kitty terminal emulator. You can also specify the program to run inside kitty as normal arguments
following the options. For example: kitty --hold sh -c "echo hello, world"
For comprehensive documentation for kitty, please see: <https://sw.kovidgoyal.net/kitty/>
Options
--app-id <CLS>, --class <CLS>
On Wayland set the application id. On X11 set the class part of the WM_CLASS window property.
Default: kitty
--name <NAME>, --os-window-tag <NAME>
On Wayland, set the window tag, when specified. On X11, set the name part of the WM_CLASS
property, when unset, defaults to using the value from kitty --class.
--title <TITLE>, -T <TITLE>
Set the OS window title. This will override any title set by the program running inside kitty,
permanently fixing the OS window's title. So only use this if you are running a program that does
not set titles.
--config <CONFIG>, -c <CONFIG>
Specify a path to the configuration file(s) to use. All configuration files are merged onto the
builtin kitty.conf, overriding the builtin values. This option can be specified multiple times to
read multiple configuration files in sequence, which are merged. Use the special value NONE to not
load any config file.
If this option is not specified, config files are searched for in the order:
$XDG_CONFIG_HOME/kitty/kitty.conf, ~/.config/kitty/kitty.conf, $XDG_CONFIG_DIRS/kitty/kitty.conf.
The first one that exists is used as the config file.
If the environment variable KITTY_CONFIG_DIRECTORY <#envvar-KITTY_CONFIG_DIRECTORY> is specified,
that directory is always used and the above searching does not happen.
If /etc/xdg/kitty/kitty.conf exists, it is merged before (i.e. with lower priority) than any user
config files. It can be used to specify system-wide defaults for all users. You can use either -
or /dev/stdin to read the config from STDIN.
--override <OVERRIDE>, -o <OVERRIDE>
Override individual configuration options, can be specified multiple times. Syntax: name=value.
For example: kitty -o font_size=20
--directory <DIRECTORY>, --working-directory <DIRECTORY>, -d <DIRECTORY>
Change to the specified directory when launching. Default: .
--detach [=no]
Detach from the controlling terminal, if any. On macOS use open -a kitty.app -n instead.
--detached-log <DETACHED_LOG>
Path to a log file to store STDOUT/STDERR when using --detach
--session <SESSION>
Path to a file containing the startup session (tabs, windows, layout, programs). Use - to read
from STDIN. See Sessions <#sessions> for details and an example. Environment variables in the file
name are expanded, relative paths are resolved relative to the kitty configuration directory. The
special value none means no session will be used, even if the startup_session <#opt-kitty
.startup_session> option has been specified in kitty.conf. Note that using this option means the
command line arguments to kitty specifying a program to run are ignored.
--hold [=no]
Remain open, at a shell prompt, after child process exits. Note that this only affects the first
window. You can quit by either using the close window shortcut or running the exit command.
--single-instance [=no], -1 [=no]
If specified only a single instance of kitty will run. New invocations will instead create a new
top-level window in the existing kitty instance. This allows kitty to share a single sprite cache
on the GPU and also reduces startup time. You can also have separate groups of kitty instances by
using the kitty --instance-group option.
--instance-group <INSTANCE_GROUP>
Used in combination with the kitty --single-instance option. All kitty invocations with the same
kitty --instance-group will result in new windows being created in the first kitty instance within
that group.
--wait-for-single-instance-window-close [=no]
Normally, when using kitty --single-instance, kitty will open a new window in an existing instance
and quit immediately. With this option, it will not quit till the newly opened window is closed.
Note that if no previous instance is found, then kitty will wait anyway, regardless of this
option.
--listen-on <LISTEN_ON>
Listen on the specified socket address for control messages. For example, kitty
--listen-on=unix:/tmp/mykitty or kitty --listen-on=tcp:localhost:12345. On Linux systems, you can
also use abstract UNIX sockets, not associated with a file, like this: kitty
--listen-on=unix:@mykitty. Environment variables are expanded and relative paths are resolved with
respect to the temporary directory. To control kitty, you can send commands to it with kitten @
using the kitten @ --to <#cmdoption-kitten-to> option to specify this address. Note that if you
run kitten @ within a kitty window, there is no need to specify the kitten @ --to <#
cmdoption-kitten-to> option as it will automatically read from the environment. Note that this
will be ignored unless allow_remote_control <#opt-kitty.allow_remote_control> is set to either:
yes, socket or socket-only. This can also be specified in kitty.conf. To start in headless mode,
without an actual window, use kitty --start-as=hidden.
--start-as <START_AS>
Control how the initial kitty window is created. Default: normal Choices: fullscreen, hidden,
maximized, minimized, normal
--position <POSITION>
The position, for example 10x20, on screen at which to place the first kitty OS Window. This may
or may not work depending on the policies of the desktop environment/window manager. It never
works on Wayland. See also remember_window_position <#opt-kitty.remember_window_position> to have
kitty automatically try to restore the previous window position.
--grab-keyboard [=no]
Grab the keyboard. This means global shortcuts defined in the OS will be passed to kitty instead.
Useful if you want to create an OS modal window. How well this works depends on the OS/window
manager/desktop environment. On Wayland it works only if the compositor implements the
inhibit-keyboard-shortcuts protocol <https://wayland.app/protocols/
keyboard-shortcuts-inhibit-unstable-v1>. On macOS Apple doesn't allow applications to grab the
keyboard without special permissions, so it doesn't work.
Debugging options
--version [=no], -v [=no]
The current kitty version.
--dump-commands [=no]
Output commands received from child process to STDOUT.
--replay-commands <REPLAY_COMMANDS>
Replay previously dumped commands. Specify the path to a dump file previously created by kitty
--dump-commands. You can open a new kitty window to replay the commands with:
kitty sh -c "kitty --replay-commands /path/to/dump/file; read"
--dump-bytes <DUMP_BYTES>
Path to file in which to store the raw bytes received from the child process.
--debug-gl [=no], --debug-rendering [=no]
Debug rendering commands. This will cause all OpenGL calls to check for errors instead of ignoring
them. Also prints out miscellaneous debug information. Useful when debugging rendering problems.
--debug-input [=no], --debug-keyboard [=no]
Print out key and mouse events as they are received.
--debug-font-fallback [=no]
Print out information about the selection of fallback fonts for characters not present in the main
font.
--watcher <WATCHER>
This option is deprecated in favor of the watcher <#opt-kitty.watcher> option in kitty.conf and
should not be used.
Tabs and windows
kitty is capable of running multiple programs organized into tabs and windows. The top level of
organization is the OS window <#term-os_window>. Each OS window consists of one or more tabs <#term-tab>.
Each tab consists of one or more kitty windows <#term-window>. The kitty windows can be arranged in
multiple different layouts <#term-layout>, like windows are organized in a tiling window manager. The
keyboard controls (which are all customizable <#conf-kitty-shortcuts>) for tabs and windows are:
Scrolling

The scroll actions only take effect when the terminal is in the main screen. When the alternate screen
is active (for example when using a full screen program like an editor) the key events are instead passed
to program running in the terminal.

Additionally, you can define shortcuts in kitty.conf to focus neighboring windows and move windows around
(similar to window movement in vim):
map ctrl+left neighboring_window left
map shift+left move_window right
map ctrl+down neighboring_window down
map shift+down move_window up
...
You can also define a shortcut to switch to the previously active window:
map ctrl+p nth_window -1
nth_window <#action-nth_window> will focus the nth window for positive numbers (starting from zero) and
the previously active windows for negative numbers.
To switch to the nth OS window, you can define nth_os_window <#action-nth_os_window>. Only positive
numbers are accepted, starting from one.
You can define shortcuts to detach the current window and move it to another tab or another OS window:
# moves the window into a new OS window
map ctrl+f2 detach_window
# moves the window into a new tab
map ctrl+f3 detach_window new-tab
# moves the window into the previously active tab
map ctrl+f3 detach_window tab-prev
# moves the window into the tab at the left of the active tab
map ctrl+f3 detach_window tab-left
# moves the window into a new tab created to the left of the active tab
map ctrl+f3 detach_window new-tab-left
# asks which tab to move the window into
map ctrl+f4 detach_window ask
Similarly, you can detach the current tab, with:
# moves the tab into a new OS window
map ctrl+f2 detach_tab
# asks which OS Window to move the tab into
map ctrl+f4 detach_tab ask
Finally, you can define a shortcut to close all windows in a tab other than the currently active window:
map f9 close_other_windows_in_tab
