Main Issues

Why (when) use a command line instead of a GUI?

  • Flexibility: menus limited, command line almost unlimited (aliases/pipes/etc.)
  • Time: keeping hands on keyboard vs.
    moving hand to mouse/
    moving mouse and clicking/
    moving hand back to keyboard
  • Can launch windows from command line:
    gimp &
    just as window manager menus do. Also, pass arguments:
    netscape &
    to avoid having to click and type after Netscape opens.
  • Ease of use: yes! Needs some memorization and/or a reference book, card, etc.
  • Best for heavy users: learning curve, but paid back many times over.
