Linux by examples initial goal is to ease the learning process for Linux beginner users. We have now advanced away from explaining command line by examples. We now plan to go back to basics and this posting will concentrate on assisting the new comers

  • who have no idea what “command line” is
  • who wants to learn more about command line
  • who had just downloaded Ubuntu and having fun playing with Graphic User Interface (GUI).

  • Linux seems to drag more attention compare to pass few years back. For that Ubuntu have done a great job to improves the user friendliness of the GNU/Linux operating system, that makes using Ubuntu Linux have no different from using Windows XP or Mac OS. Compiz and Beryl provides a way to turns your Linux Desktop into a very fancy 3D desktop, where a lots of people who wants to try out Linux is because of this.

    But people have forgotten that the power of GNU/Linux system is command line, which provides you a different ways of communicating with your system. You may discover that every single GUI is actually a command where you can issue from the console/virtual terminal. For example, gaim is a GUI application like ICQ, MSN messenger, but if you can runs it from the console and asking whats command alternatives options it provides.

    gaim --help
    
    Pidgin 2.0.0beta7devel
    Usage: gaim [OPTION]...
    
      -c, --config=DIR    use DIR for config files
      -d, --debug         print debugging messages to stdout
      -h, --help          display this help and exit
      -n, --nologin       don't automatically login
      -l, --login[=NAME]  automatically login (optional argument NAME specifies
                          account(s) to use, separated by commas)
      -v, --version       display the current version and exit
    

    The outcome tells you that, you can run gaim with different config, you can open gaim without automatically login etc. By clicking the gaim icon in menu bar, you can’t specified the additional options at the same time.
