...but people still use command line , I just don't get it . is it because that you look kwel when you are using command line than GUI !!!!!
not at all actually. when it comes down to it, you just can not practically include every function in a gui app that is a frontend for a command line tool.
you can not use gui apps in shell scripts, (which would very much help your problem of adding 20 users, which by the way, would be just as tedious if done from a gui app)
the command line is where the power is, you have full control of your system, and to be quite honest, most CLI tools are NOT hard to learn. people just dont want to RTFM!!
for your desktop machine, of course you are going to want a GUI, i use KDE on my desktop. but if you think there is X at all on my server you are wrong. it is unecessary overhead. you dont need GUI apps to administer your server.
and my final point, those who become dependant on GUI apps will never become proficient at adminstering their systems. not every place is going to have the same gui apps, and some probably none at all. standard command line tools generally do not change accross platforms very much at all, and if there are differences, you have one command that (usually) will always be there:
man
one more thing, a mouse is inherently clumsy. even GUI apps have hotkeys to avoid using the slow mouse. you will be 100x faster at a command line than in X with a mouse.
