13.1. Why Use a Shell Prompt
Graphical environments for Linux have come a long way in the past
few years. You can be perfectly productive in the X Window System and
only have to open a shell prompt to complete a few tasks.
However, many Red Hat Linux functions can be completed faster from the shell
prompt than from a graphical user interface (GUI).
In less time than it might take to open a file manager, locate a
directory, and then create, delete, or modify files from a GUI, a task
can be finished with just a few commands at a shell prompt.
A shell prompt looks similar to other command-line interfaces with
which you might be familiar. Users type commands at a shell prompt, the
shell interprets these commands, and then the shell tells the OS what to
do. Experienced users can write shell scripts to expand their
capabilities even further.
