How to launch a command-line application without having to type the command?

Question

I'm trying to write a python script that will launch alsamixer. alsamixer is a command-line application, that you typically launch by:

1. Opening up a Terminal.
2. Typing alsamixer.

I'm trying to make alsamixer something I can launch, so that after clicking it, it will launch a terminal with alsamixer already running before any physical interaction from me.

Answer 1

You can launch an xterm which first runs a command via

xterm -e alsamixer

Armed with that knowledge you can easily make a script that launches the terminal:

echo '#!/usr/bin/env sh\n\nxterm -e alsamixer' > mixer ; chmod +x mixer

Move that script to your desktop or whatever. If you use a different terminal it might have different options, -e is fairly standard though.
