# Desktop Launcher Actions (Linux)
|
|
|
|
## Overview
|
|
|
|
On many Linux environments, you can add custom entries to the system launcher
|
|
by modifying the `.desktop` file. For Canonical's Unity documentation, see
|
|
[Adding Shortcuts to a Launcher][unity-launcher]. For details on a more generic
|
|
implementation, see the [freedesktop.org Specification][spec].

|

|
|
To create a shortcut, you need to provide `Name` and `Exec` properties for the
|
|
entry you want to add to the shortcut menu. Unity will execute the command
|
|
defined in the `Exec` field after the user clicked the shortcut menu item.
|
|
An example of the `.desktop` file may look as follows:
|
|
|
|
```plaintext
|
|
Actions=PlayPause;Next;Previous
|
|
|
|
[Desktop Action PlayPause]
|
|
Name=Play-Pause
|
|
Exec=audacious -t
|
|
OnlyShowIn=Unity;
|
|
|
|
[Desktop Action Next]
|
|
Name=Next
|
|
Exec=audacious -f
|
|
OnlyShowIn=Unity;
|
|
|
|
[Desktop Action Previous]
|
|
Name=Previous
|
|
Exec=audacious -r
|
|
OnlyShowIn=Unity;
|
|
```
|
|
|
|
The preferred way for Unity to instruct your application on what to do is using
|
|
parameters. You can find them in your application in the global variable
|
|
`process.argv`.
