jumpapp
A run-or-raise application switcher for any X11 desktop
The idea is simple โ bind a key for any given application that will:
- launch the application, if it's not already running, or
- focus the application's most recently opened window, if it is running.
Pressing the key again will cycle to the application's next window, if there's more than one.
In short, jumpapp is probably the fastest way for a keyboard-junkie to switch between applications in a modern desktop environment. Once installed, all you have to do is configure the key bindings you want to use:
Synopsis
Usage: jumpapp [OPTION]... COMMAND [ARG]...
Jump to (focus) the existing window for an application, if it's running.
Otherwise, launch COMMAND (with optional ARGs) to start the application.
Options:
-r -- cycle through windows in reverse order
-f -- force COMMAND to launch if process found but no windows found
-m -- if a single window is already open and in focus - minimize it
-n -- do not fork into background when launching COMMAND
-N -- don't launch if no window is found
-p -- always launch COMMAND when ARGs passed
(see Argument Passthrough in man page)
-L -- list matching windows for COMMAND and quit
-t NAME -- process window has to have NAME as the window title
-c NAME -- find window using NAME as WM_CLASS (instead of COMMAND)
-i NAME -- find process using NAME as the command name (instead of COMMAND)
-w -- only find the applications in the current workspace
-R -- bring the application to the current workspace when raising
(the default behaviour is to switch to the workspace that the
application is currently on)
-C -- center cursor when raising application

Argument Passthrough (-p option)
Many applications keep track of what windows they have open so that if you run the command again, it will interact with the existing application window instead of launching a new instance of the application.
Take Firefox, for example. If you already have a Firefox window open and you
run firefox https://github.com/, Firefox won't start a new instance. What it
does is open a new tab in the existing window and browse to the URL you passed.
Especially in the case of Desktop Entry files, we
want to preserve this behavior. With jumpapp -p COMMAND [ARGs]..., when you
include one or more ARGs, COMMAND is always executed in order to pass the ARGs
to the running application. But if no ARGs are included, jumpapp will
behave normally.
A Wrapper Around wmctrl(1)
All the heavy lifting is done by Tomรกลก Stรฝblo's powerful wmctrl. You must have it installed to use jumpapp.
jumpapp was built for the GNOME desktop environment. There's a good chance though that it'll work on any window manager supported by wmctrl.
XBindKeys
If your desktop environment doesn't offer a way to bind keys to commands โ or if it's too limited โ take a look at XBindKeys.
Example .xbindkeysrc:
"jumpapp chromium"
control + alt + c
"jumpapp -r chromium"
shift + control + alt + c
"jumpapp firefox"
control + alt + f
"jumpapp -r firefox"
shift + control + alt + f
"jumpapp gnome-terminal"
control + alt + t
"jumpapp -r gnome-terminal"
shift + control + alt + t
jumpappify-desktop-entry(1)
jumpapp ships with a helper utility:
Usage: jumpappify-desktop-entry SOMEFILE.desktop
Given a desktop entry file (*.desktop), output a new desktop entry file that
wraps the application's `Exec` in a call to jumpapp(1).
EXAMPLES
jumpappify-desktop-entry /usr/share/applications/chromium-browser.desktop \
> ~/.local/share/applications/chromium-browser.desktop
Or convert multiple in one go:
for entry in /usr/share/applications/{firefox,gnome-terminal}.desktop; do
target=~/".local/share/applications/$(basename "$entry")"
jumpappify-desktop-entry "$entry" >"$target"
done
