Bash and the Command Line¶
This section introduces you to one of the most powerful tools of the GNU/Linux OS: The Command Line Interface. Most Linux newcomers fear it because they feel lost in it, like bumping into the furniture in a strange dark room. Just a black box with a blinking line...
Like many other things in life, once you learn how to use it, it's really not that bad - in some ways, it's even better than the GUI. For instance, installing software via the CLI is simpler and faster than using a GUI Software Center.
A few words about these guides¶
This is only a basic practical introduction to each of the commands. If you need more in-depth information, you should research some more on the Internet, or better yet: read the command's Manual Page .
Note
You can learn much more by reading the manual page for each command, by entering man <command> at the terminal prompt (substitute <command> with the actual command you want to look up 
).
