flexfax: programming help

[Lee Howard <faxguy@deanox.com>]

I'm trying to extract the fax number of an intended recipient from the body
of an e-mail.  The following command works, but it's bulky.  I'm new to
Perl/sed/grep programming, can anybody help me tidy this up?  Thanks.

grep -e FAXNUMBER -i | sed -e 's/[a-zA-Z]//g' | sed -e 's/\W//g'
