Re: Weird grep behavior -- LINUX400

That's ok, it's the kind of "STFW" or "RTFM" that I've come to expect from fellow linux "enthusiasts"

Along this topic, does anyone have a good reference on regular

Yes, by default grep uses basic regular expressions.
The dot means to match any single character.
Use man grep and see the regular expression section.

As you've seen,
 Use fgrep to grep for fixed strings (or grep -F)
 Use egrep to grep using extended regular expressions (or grep -E).
