You know I’m still rather new to Linux…okay I might be at a novice level by now but it’s still hard to remember all those commands. Granted a lot of Linux distros now offer GUI (graphical user interface), you’d think you could just point and click with your mouse without needing to know much else.
Well, from an administrator’s standpoint I find it more reliable and much more efficient to use the command line in Linux to ensure things get done correctly…you know the way you intended.
If you’re new at Linux or a crafty veteran, check out these few commands as they will definitely help.
