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.

Installation

Installing dmenu is simple:

# pacman -S dmenu

run it

$ dmenu_run

Configuration

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.

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" | dmenu
no locale support
Segmentation fault

Make sure $LANG is set to something valid. For example, I was experiencing this problem because I had set $LANG to "en_US.UTF_8" in /etc/locale.conf. In my case it should have been "en_US.UTF-8".

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

More font support

dmenu can be patched to allow using more fonts which don't seem to be working with the version from mainstream. The patched version can be found on AUR. Using this version, fonts like Droid Sans mono can be set.

$ dmenu_run -fn 'Droid Sans Mono-9'
