dmenu is a fast and lightweight dynamic menu for X. It reads arbitrary text from stdin, and creates a menu with one item for each line. The user can then select an item, through the arrow keys or typing a part of the name, and the line is printed to stdout. dmenu_run is a wrapper that ships with the dmenu distribution that allows its use as an application launcher.


Install dmenu from the official repositories.

You may run dmenu with

$ dmenu_run


Now, you will want to attach the dmenu_run command to a keystroke combination. This can be done either via your window manager or desktop environment configuration, or with a program like xbindkeys. See the Hotkeys article for more information. Also, it is helpful to Prelink dmenu.

Displaying Custom Items

Custom items may be shown by piping them into dmenu. For example:

$ echo "first\nsecond\nthird" | dmenu


dmenu can be patched to allow using xft fonts which don't seem to be working with the version from upstream. The patched version can be found in the dmenu-xftAUR package from the AUR. Using this version, fonts like Droid Sans Mono can be set.

$ dmenu_run -fn 'Droid Sans Mono-9'


Strange segfaulting

If executing dmenu_run results in an error similar to this:

 $ dmenu_run
 /usr/bin/dmenu_run: line 15: 1879 Segmentation fault           dmenu "$@" < "$cache"

And running dmenu crashes like the following:

 $ echo "blahblahblah" 

Make sure $LANG is set to something valid. For example, this problem may occur if one needs to set $LANG to en_US.UTF_8 or something similar in /etc/locale.conf (see locale.conf).

Keep in mind that the value contained in $LANG must be uncommented in /etc/locale.gen and generated via locale-gen as well.
