Launching Programs From the Command Line


I have been using Mandrake Linux for a few monthes now, but the whole time I have been using KDE and now I would like to try using the commandline instead. I tried setting the boot options ot goto the commandline rather than automatically going to the graphical log in menu. I tried running gAIM after logging in as my user and it gave me this error:

(gaim:2493): gtk-WARNING **: cannot open display:

How do I make it so I can launch gAIM from the command line?

GAIM is a graphical client, you need X running in order to run it.

When you say "command line" do you mean loading up xterm while inside of KDE, or that you stopped booting up into a GUI, and on the console typed in "gaim"?

You have to have X running to run gaim. All gnome and kde apps need X. Some programs are designed to run with ncurses, a limited type of graphics that you can run in a command line environment. The links browser is one. You may be able to find an ncurses IM client but I'm not aware of any as I'm not that much into it but one probably exists.

Well, what I was doing was not running the GUI at all.

When people talk about using Linux from the command line, and typing everything themselves, do they mean they just run an xterm from inside KDE or Gnome or whatever window enviorment they use? Or do they just use programs made to run with ncurses?

Almost anything can be done from the command line. But you can't run GUI apps directly. Some apps are engines that just have a GUI frontend that's dispensable. (cdrecord and its various front ends like xcdroast and k3b and so on.) Some are exclusively GUI apps and you need a different console app for the functionality. (mozilla's only a GUI app - but you can surf with lynx or w3m or whatever.) For IM, I've never used it, but maybe

would work.

Strictly speaking, running Linux 'from the command line' would be like on my P100 where I don't even have X installed (this time). But you can run almost everything (including GUI apps) from X with just an xterm. Or you can never touch an xterm (in theory, I guess) and run everything from desktop widgets. It just depends on your style and interests and your box's capabilities.
