How can I find *.desktop files?

Question

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?

Answer 1

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"

Answer 2

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.

Answer 3

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.

You can find all directories with desktop files in the XDG_DATA_DIRS environment variable. The *.desktop files can be in the applications directory in each of the directory in that variable. E.g.:

> echo $XDG_DATA_DIRS
/usr/share/ubuntu:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop

You can use this bash script to list all desktop files used by the system (e.g. to build the panel or applications menu):

for p in ${XDG_DATA_DIRS//:/ }; do 
  find $p/applications -name '*.desktop' 
done

It seems that desktop files can also be placed in one more directory, which isn't in the XDG_DATA_DIRS variable:

• ~/.local/share/applications

So, the complete script to find all *.desktop files in the system is:

DATA_DIRS="$XDG_DATA_DIRS:$HOME/.local/share"
for p in ${DATA_DIRS//:/ }; do
  find $p/applications -name '*.desktop' 
done

I didn't find any documentation for this but there's some information about this environment variable here: https://unix.stackexchange.com/a/531664

Answer 5

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

Answer 6

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.

Answer 7

• /usr/share/applications (most applications, admin rights)
• ~/.local/share/applications (personal ones)

Answer 8

Commandline output for all .desktop files in your system.

sudo find / -type f -name "*.desktop" -exec echo $PATH {} \;

This one will dump the terminal spew out to a text file on your desktop so you can actually read it.

sudo find / -type f -name "*.desktop" -exec echo $PATH {} \; 1>~/Desktop/Desktop-files-output.txt

once found, if its not in /usr/share/applications you can do sudo ln -s [the .desktop name] /usr/share/applications/[the .desktop name] which will add a link to that directory and make it appear in your applications menu.

if it is in there; change or add these lines to the .desktop file;

NoDisplay=false
Hidden=false

If it doesn't have a .desktop, you can make one;

cat>>Skrooge.desktop<<EOL
#!/usr/bin/env xdg-open
[Desktop Entry]
Name=name
Comment=[what it does]
Path=/working/directory/comment/this/out/if/you/are/going/to/use/$HOME
Exec=[the command line command you use to launch it.]
Icon=/usr/share/icons/icon.png
Type=Application
NoDisplay=false
Hidden=false
Categories=menucategory1;category2
Terminal=false[unless its a commandline only program like htop]
EOL

Then run chmod +x Skrooge.desktop

Once made and proven to work, drop it in /usr/share/applications so it shows up in your applications menu.

Answer 9

I just want to add where Flatpak saves desktop files.

/var/lib/flatpak/exports/share/applications/

NOT IMPORTANT: The same files are individually in /var/lib/flatpak/app/APPFLATPAKNAME/current/active/files/share/applications/ where APPFLATPAKNAME is, as you guess, the name of the Flatpak app. But I think system uses the files in the previous path, instead of these.

Answer 10

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
