Let’s say you have a .png file, a .txt file and an .mp3 file.
If you are using Konqueror (or Nautilus under Gnome), just double click, the program you’ve chosen for this type of file will be launched : a picture viewer for the .png file, a text viewer for the .txt file, and a multimedia player for the .mp3 file.
Now, you’re using the console, and you don’t want to bother wondering which program you want to launch if you want to view a file. You can’t “execute” it either, because a .png file is just not executable (it’s not a program nor a script !).
What happens when you double-click a file in Konqueror/Nautilus is : “okay, what’s the file type ? got it, I will launch the right program and ask it to view the file”. There’s a way to do that using the console, too.
Without it, if you want to listen to your .mp3 file, you can type:
But it implies you have to know each program name for each type file. Not very handy.
Here comes the solution.
In both cases, the correct program will be launched to view the file, according to your KDE/Gnome preferences, yay ! If you use this command often, you can set a shorter alias in your .bashrc file (“kfmclient exec” is a bit long to type, and Linux is about efficiency, right ?), adding the following line to it:
