grep foo bar

Looks for the text "foo" in file "bar"

Put quotes around the text if it has spaces in it

e.g grep "foo bar" baz

Looks for the text "foo bar" in file "baz"

grep is also useful for searching through command outputs.  A lame example 
might be looking in the process list for whether a particular program is 
running:

ps ax | grep foo

Looks for "foo" anywhere in the process list.

That's probably all you need to know to make it useful.
