kitty(1) kitty kitty(1) Name 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 exam- ple: 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> Set the class part of the WM_CLASS window property. On Wayland, it sets the app id. Default: kitty --name <NAME> Set the name part of the WM_CLASS property. 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 configu- ration 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, ~/.con- fig/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 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 ei- ther - or /dev/stdin to read the config from STDIN. --override <OVERRIDE>, -o <OVERRIDE> Override individual configuration options, can be specified mul- tiple times. Syntax: name=value. For example: kitty -o font_size=20 --directory <DIRECTORY>, --working-directory <DIRECTORY>, -d <DIREC- TORY> Change to the specified directory when launching. Default: . --detach Detach from the controlling terminal, if any. Not available on macOS. On macOS use open -a kitty.app -n instead. --session <SESSION> Path to a file containing the startup session (tabs, windows, layout, programs). Use - to read from STDIN. See Startup Ses- sions 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 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 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, -1 If specified only a single instance of kitty will run. New invo- cations will instead create a new top-level window in the exist- ing 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 --in- stance-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 re- sult in new windows being created in the first kitty instance within that group. --wait-for-single-instance-window-close 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 --lis- ten-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 ex- panded and relative paths are resolved with respect to the tem- porary directory. To control kitty, you can send commands to it with kitten @ using the kitten @ --to option to specify this ad- dress. Note that if you run kitten @ within a kitty window, there is no need to specify the kitten @ --to option as it will automatically read from the environment. Note that this will be ignored unless allow_remote_control is set to either: yes, socket or socket-only. This can also be specified in kitty.conf. --start-as <START_AS> Control how the initial kitty window is created. Default: nor- mal Choices: fullscreen, maximized, minimized, normal Debugging options --version, -v The current kitty version. --dump-commands 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, --debug-rendering Debug rendering commands. This will cause all OpenGL calls to check for errors instead of ignoring them. Also prints out mis- cellaneous debug information. Useful when debugging rendering problems. --debug-input, --debug-keyboard Print out key and mouse events as they are received. --debug-font-fallback 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 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. Each OS win- dow consists of one or more tabs. Each tab consists of one or more kitty windows. The kitty windows can be arranged in multiple different layouts, like windows are organized in a tiling window manager. The keyboard controls (which are all customizable) for tabs and windows are: Scrolling +---------------------------+----------------------------+ | Action | Shortcut | +---------------------------+----------------------------+ | Line up | ctrl+shift+up (also ++ and | | | + on macOS) | +---------------------------+----------------------------+ | Line down | ctrl+shift+down (also ++ | | | and + on macOS) | +---------------------------+----------------------------+ | Page up | ctrl+shift+page_up (also + | | | on macOS) | +---------------------------+----------------------------+ | Page down | ctrl+shift+page_down (also | | | + on macOS) | +---------------------------+----------------------------+ | Top | ctrl+shift+home (also + on | | | macOS) | +---------------------------+----------------------------+ | Bottom | ctrl+shift+end (also + on | | | macOS) | +---------------------------+----------------------------+ | Previous shell prompt | ctrl+shift+z (see Shell | | | integration) | +---------------------------+----------------------------+ | Next shell prompt | ctrl+shift+x (see Shell | | | integration) | +---------------------------+----------------------------+ | Browse scrollback in less | ctrl+shift+h | +---------------------------+----------------------------+ | Browse last cmd output | ctrl+shift+g (see Shell | | | integration) | +---------------------------+----------------------------+ 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. Tabs +-------------------+----------------------------+ | Action | Shortcut | +-------------------+----------------------------+ | New tab | ctrl+shift+t (also +t on | | | macOS) | +-------------------+----------------------------+ | Close tab | ctrl+shift+q (also +w on | | | macOS) | +-------------------+----------------------------+ | Next tab | ctrl+shift+right (also ++ | | | and ++] on macOS) | +-------------------+----------------------------+ | Previous tab | ctrl+shift+left (also ++ | | | and ++[ on macOS) | +-------------------+----------------------------+ | Next layout | ctrl+shift+l | +-------------------+----------------------------+ | Move tab forward | ctrl+shift+. | +-------------------+----------------------------+ | Move tab backward | ctrl+shift+, | +-------------------+----------------------------+ | Set tab title | ctrl+shift+alt+t (also ++i | | | on macOS) | +-------------------+----------------------------+ Windows +-----------------------+----------------------------+ | Action | Shortcut | +-----------------------+----------------------------+ | New window | ctrl+shift+enter (also + | | | on macOS) | +-----------------------+----------------------------+ | New OS window | ctrl+shift+n (also +n on | | | macOS) | +-----------------------+----------------------------+ | Close window | ctrl+shift+w (also ++d on | | | macOS) | +-----------------------+----------------------------+ | Resize window | ctrl+shift+r (also +r on | | | macOS) | +-----------------------+----------------------------+ | Next window | ctrl+shift+] | +-----------------------+----------------------------+ | Previous window | ctrl+shift+[ | +-----------------------+----------------------------+ | Move window forward | ctrl+shift+f | +-----------------------+----------------------------+ | Move window backward | ctrl+shift+b | +-----------------------+----------------------------+ | Move window to top | ctrl+shift+` | +-----------------------+----------------------------+ | Visually focus window | ctrl+shift+f7 | +-----------------------+----------------------------+ | Visually swap window | ctrl+shift+f8 | +-----------------------+----------------------------+ | Focus specific window | ctrl+shift+1, ctrl+shift+2 | | | ... ctrl+shift+0 (also +1, | | | +2 ... +9 on macOS) | | | (clockwise from the | | | top-left) | +-----------------------+----------------------------+ Additionally, you can define shortcuts in kitty.conf to focus neighbor- ing 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 win- dow: map ctrl+p nth_window -1 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. Only pos- itive 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 Other keyboard shortcuts The full list of actions that can be mapped to key presses is available here.
