What's the best way to become a UNIX guru?
Learn UNIX.

There are two great resources available to
the UNIX programmer that give general help
and often examples.  One is the "man" command.

ex. man vi
The other is the "-?" command line option.
ex. sort -?

These will tell you all you need to know
about most commands.

I suggest that newbies look at the following
man pages:

vi - probably the best text editor ever made
sh/ksh/csh - my favorite flavor is ksh
awk - fantastic!!
sed - dull but indispensable

Spend some time looking at the man pages.
At the end there is usually a list of related
commands, a great way to enhance your UNIX
vocabulary!
