"What's better, a graphical interface or the Linux command line?
Both of them.
"They blend seamlessly on Linux so you don't have to choose. A
good graphical user interface (GUI) has a logical, orderly flow,
helps guide you to making the right command choices, and is
reasonably fast and efficient.
"Since this describes a minority of all GUIs, I still live on
the command line a lot. The CLI has three advantages: it's faster
for many operations, it's scriptable, and it is many times more
flexible. Linux's Unix heritage means you can string together
commands in endless ways so they do exactly what you want."
