Q. How can I find all English words that start with a certain prefix?
A. If you are using RedHat/Fedora make sure you have the "words" package
installed:
yum install words
Then you can do:
grep ^Dw /usr/share/dict/words
To find all the English words that begin with "Dw".
(This was a "brain teaser" in my local newspaper today.)
Amazingly, Linux has a command that does this: look.

Of course, you can use grep to do many other queries.
