No one can remember everything. Even the best and most experienced
systems administrators use man pages regularly. Looking up complicated
information is easy because this frees you from having to recall it all,
enabling you to focus on your task rather than punishing you for not
remembering syntax.


NOTE
Nearly every one of the hundreds of commands included with Linux has a
man page; however, some do not have man pages or have only simple ones.
You can use the info command to read more detailed information about
some commands or as a replacement for others. For example, to learn even
more about info (which has a rather extensive manual page), use the
info command like this:

through the man command. Linux offers many other helpful commands for
accessing its documentation. You can use the apropos command (for
example, with a keyword such as partition) to find commands related to
partitioning, like this:
