Unix In A Nutshell is the "standard" book on *nix commands.
But it doesn't really contain a lot that you can't find
on the 'man' pages or in 'info'.

For starters, do this:
    man bash

... that teaches you all sortsa stuff about the bash shell,
which applies to all the commands you enter at the
shell prompt -- things like expansion of wildcards,
etc. are basic to all commands.

To find a command that will help you snorkel, just type
    man -k snorkel
or
    apropos snorkel

The result will be a list of commands that may have something
to do with snorkeling, and then you just do
    man <command>

e.g.,  man ls    or   man vi   or   man date

Some man pages say that you need to use info for the
command in question.  To learn how to use info, just
type:
     info info
