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

Install the dmenu package from the official repositories. If you want the development build from git, install the dmenu-gitAUR package from the Arch User Repository.

Various patched variants exist which extend dmenu's default functionality. Consider installing one of the following packages from the AUR:

  • dmenu2AUR: dmenu fork with many useful patches applied and additional capabilities added including dimming, specifying a custom opacity, and underlining.

You may run dmenu with:

$ 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.

Displaying Custom Items

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

$ echo -e "first\nsecond\nthird" | dmenu

Manually Adding Items

dmenu will look for executables in the directories defined in your $PATH. See the following article for information on modifying your $PATH: Environment variables

Fonts

Tango-view-refresh-red.pngThis article or section is out of date.Tango-view-refresh-red.png

Reason: Since dmenu 4.6 XFT font rendering is enabled by default: 4.6 Release Notes. Specifying fonts via X logical font description does not work anymore. Instead fontconfig's font.conf syntax is used. (Discuss in Talk:Dmenu#)

dmenu can display fonts using the X logical font description as found using the tool xfontsel, which is provided by xorg-xfontsel. This example will run dmenu using the terminus-font:

$ dmenu_run -fn "-xos4-terminus-medium-r-*-*-14-*"

The syntax is similar if using a dmenu variant patched with XFT support.

$ dmenu_run -fn 'Droid Sans Mono-9'

Support for shell aliases

dmenu does not support shell aliases. To have dmenu recognize your aliases, install the dmenu-recent-aliasesAUR[broken link: archived in aur-mirror] package from the AUR and run dmenu_run_aliases. Your aliases must be in either ~/.bash_aliases or ~/.zsh_aliases to be recognized by dmenu_run_aliases.

Troubleshooting

No locale support

Running dmenu_run results in the following error message:

$ dmenu_run
no locale support

Make sure that the environment variable LANG is correctly set. See the following for more information: Locale#Troubleshooting

Missing menu entries

If certain entries are missing from dmenu, the cache may be malformed. Delete it and restart dmenu.

$ rm ~/.dmenu_cache
$ rm ~/.cache/dmenu_run

Note that there will most likely be only one cache file, depending on if $XDG_CACHE_HOME is set. See the contents of /usr/bin/dmenu_run for more information.
