Getting Help

Whether you are new to Linux or a long-time user, from time to time, you'll need help. It's impossible to remember all the commands and their parameters. Almost every command has a --help parameter, and there is sometimes documentation installed in the /usr/share/doc directory, but the most important sources of information are the information documents and man pages.

Using the man pages

There is a saying, Read The Fine Manual (RTFM), and sometimes people replace the word fine with another, less friendly word. Almost every command has a manual: a man page provides you with all the information you need. And yes, not all man pages are easy to read, especially older ones, but if you use man pages frequently, you'll get used to them, and you'll be able to find the information you need quickly enough. Normally, man pages are installed on your system, and they are available online: http://man7.org/linux/man-pages.

Note that the man pages are removed...
