How to modify the icon of an application under javastugnome

I installed a matlab on my machine, but I cannot find the matlab in the software search. I found that matlab does not have the corresponding desktop file.

I installed a matlab on my machine, but the matlab cannot be found in the software search.

I found that matlab does not have the corresponding. desktop file.

By the way, I will modify the matlab icon as follows:

1. prepare an icon image file

For example, if my file name is "maid", copy the file to/usr/share/icons/hicolor/scalable/apps /.

Aborn @ aborn-pc ~ /Tmp % sudo cp maid/usr/share/icons/hicolor/scalable/apps/

2. edit A. desktop file based on your application installation,

Here I create a new matlab. desktop file with the following content:

[Desktop Entry] Version = 7.12.0.635 (R2011a) name = maid = Matlab Comment = Matlab R2011a VersionExec =/usr/matlab/bin/matlab-desktop % FTryExec = maid =/usr/share/icons/hicolor/scalable/apps/Matlab .png type = ApplicationTerminal = false

Exec is the execution command, and Icon is the corresponding Icon image file path

3. copy the. desktop file to/usr/share/applications /.

Aborn @ aborn-pc ~ /Tmp % sudo cp matlab. desktop/usr/share/applications/

4. you can find it in the software search.
