## Localation of .desktop Config

user:

~/.local/share/applications/

system:

/usr/local/share/applications
/usr/share/applications

## OSU!

I have an AppImage file, osu.AppImage. I want it appear in the application menu so I can search it anywhere.

You can put the AppImage anywhere you want. For me I put it in `~/Applications` for my apps.

mkdir ~/Applications

I also created a dir `~/Applications/icons` for app icons.

mkdir ~/Applications/icons

Create and edit `.desktop` file.

nano ~/.local/share/applications/osu.desktop

Write these to set AppImage location and icons, etc.

[Desktop Entry]
Name=osu!
Comment=Rhythm is just a click away!
Exec=/home/junner/Applications/osu.AppImage
Terminal=false
Type=Application
Categories=Game;
Icon=/home/junner/Applications/icons/lazer.png

Update Menu

update-desktop-database ~/.local/share/applications/

Now we can see osu!


## Matlab

The setting is a bit different.

I symlinked it first.

cd ~/Applications
ln -s /media/junner/vedal/PROGRAM/matlab_2025a/bin/matlab

And edited the desktop script.

[Desktop Entry]
Name=matlab
Comment=Accelerating how engineers design, develop, and deliver real innovation
Exec=/home/junner/Applications/matlab -desktop
Terminal=False
Type=Application
Categories=Utilities;
Icon=/home/junner/Applications/icons/matlab.png

Here we need a param`-desktop` after the path. I don't know why. (I didn't study this.) Probably it is because `matlab` this file is a shell script?
