To the best of my knowledge, all shortcuts in the Unity Launcher have a corresponding *.desktop file. I have one shortcut (for skrooge) that doesn't have an icon. How can I find the *.desktop file corresponding to this shortcut so that I can add an icon to it?

It's probably sitting in /usr/share/applications/ but if you want to find every .desktop file on the system run this:

find / -name '*.desktop'

or

sudo updatedb
locate *.desktop

To find files with "skrooge" in their path or name, add a grep to the command:

locate *.desktop | grep -iR "skrooge"

    locate -i "*skrooge*.desktop". Though there's mainly three places unity will look for desktop files. ~/.local/share/applications, /usr/local/share/applications and /usr/share/applications. If there are desktop files for the same command in multiple places, it'll use the left-most of the three I listed. – geirha Mar 30 '12 at 14:32
  • Showed up as /usr/share/applications/kde4/skrooge.desktop. Thanks. :) – KOVIKO Mar 30 '12 at 15:08

    This is super useful! Thank you. Note that using locate *.desktop helped me discover that desktop files from snap package installs seem to go into the /snap/ and /var/lib/snapd/desktop/applications/ directories. – Gabriel Staples Aug 10 '20 at 2:05

    locate *.desktop doesn't find anything. find / -name '*.desktop' 2> /dev/null to suppress the 'permission denied' flood. – Mark Jeronimus Oct 30 '20 at 9:48

The system stores the .desktop files in /usr/share/applications/. Unfortunately, if you open that folder in nautilus the .desktop files appears with the icon specified in the file and with the file name called out within the file. You also won't be allowed to edit these files by clicking on them and selecting edit.

To edit these files, you need to open that folder within a terminal window. Doing an ls command will show all the .desktop files with their actual names. When you locate the .desktop you wish to change, run gksudo gedit {file-name}.desktop.

It's normal practice to keep any .desktop files you create or edit in your home folder ~/.local/share/applications.

  • Running from the terminal can be handier for some, but it is also possible to drag from nautilus into gedit or another text editor. – Jon Hanna May 1 '14 at 21:40
  • what's the point of the directory "~/.local/share/applications"? Files there don't seem to be used, not I cannot add them as "shortcut" to Unity. – Malachiasz Feb 8 '15 at 15:14

    @Malachiasz Actually, the *.desktop files from ~/.local/share/applications are reloaded when session restarts. So, log out and log back in. Note that these are specific to that user. – akshay2000 Mar 21 '15 at 7:11

  • Does copying a desktop file from /usr/share/applications override the entry in ~/.local/share/applications? I'm trying to configure Firefox to use firejail, but whenever the browser updates my edits are removed if I do it in the desktop file from /usr/share/applications/. – dspacejs Oct 19 '20 at 4:52

Some additional details to supplement the other answers:

Typically, .desktop files for packages will be located in /usr/share/applications.

If you want, you could copy one to ~/.local/share/applications and edit it there without needing sudo. Items in ~/.local/share/applications will override matching items in /usr/share/applications and /usr/local/share/applications, but are only visible to your user.

Alternatively, you could place an edited copy in /usr/local/share/applications where it will override any in /usr/share/applications while also being visible to the entire system.

Note that you should not edit the .desktop files in /usr/share/applications directly; any changes you make will be automatically overwritten when the application is updated by the package manager.

Desktop files of snap packages can be found in /var/lib/snapd/desktop/applications/ and below /snap/.

I know I'm late to the party, but I have a faster solution than the one accepted as the answer:

find / -iname "*desktop" -type f -not -path "/media*" -exec grep -il skrooge '{}' ';' 2> /dev/null

It's faster because it doesn't search the data mounted file systems and most probably the desktop file is located in the system partition.

Moreover, it's more likely to find what the command from the accepted answer would miss. That's because the desktop files doesn't have to hold the application name. This command actually searches the text in every desktop file.

  • This did not work for me at all (not even with sudo). I am using Manjaro linux though, but the command should work independent of the OS as long as it has find, grep. It results in a crash of the command printing nothing. – Rahat Zaman Jun 9 '20 at 1:31
  • @RahatZaman, what's the output of running the command? – joker Jun 10 '20 at 18:12
  • there is no output. After 2-3 minutes, it just returns back to the shell prompt. – Rahat Zaman Jun 12 '20 at 7:28
  • You mentioned crash in your first comment. What do you mean by it? Also, where do drives get mounted in Manjaro? Did you update skrooge to the application you're looking for? – joker Jun 16 '20 at 12:21

I do not actually now which .desktop file becomes effective. My best guess is, from https://wiki.archlinux.org/index.php/Desktop_entries , to make a script like this and run it:

#!/bin/sh

# try to find the effective desktop file
# (there seems to be no documented standard for this)

use_if_desktop_file () {
  if [ -r "$1" ] &&
     [ "$(xdg-mime query filetype "$1")" = application/x-desktop ]; then
       echo "$1"
       exit
  fi
}

for d in ~/.local/share/applications /usr/local/share/applications \
         /usr/share/applications; do
  use_if_desktop_file "$d/$1"
  use_if_desktop_file "$d/$1.desktop"
done

# no file found
exit 1
