Bruce Smith used his Toshiba laptop running SuSE Pro v9.3 with the KLUG InFocus SVGA projector to reveal the power of the Linux CLI. He worked from the terminal window of the Gnome Desktop to give us a live demonstration. There were many good questions addressed and helpful comments exchanged.
Bruce started by showing and telling us about BASH. This is also known as the GNU Bourne Again Shell. He went through the basic commands that are needed to navigate Linux without a Graphical User Interface. Originally Linux had no GUI and the CLI was where it all happened. We saw how to look at the "man pages" to find out the command syntax and switch options. If you want to see the commands you type man –k and they appear on your screen. Bruce’s laptop only had 2,600 commands in his CLI $PATH available. WOW!
He then discussed the dynamics of alias, pipe, more, less, type, jobs, tar, su, echo $PATH, find, grep, which, and others. Unless we were going to sit there jabbering until Midnight… Thankfully, Bruce ended the presentation after a mere two hours. We barely got past the basics of the extremely powerful Linux CLI.
