Extracting numbers

Hi I am part of a academic organization and I want to send a fax to the students however there must be a quicker way to get the fax numbers extracted from the online forms they sent me.

The file looks like this (numbers are fake in order to protect identity):

Biochemistry Major
Michael Beloski
2213 Main Street
Los Angeles, CA
Phone: (619) 483-3511
Fax: (619) 483-3513
CAH

I want to extract only the fax number to a file

(619) 483-3513

Thanks

awk -F: '/Fax/{print $2}' file

sed -n 's/^Fax://p' myFile

grep Fax your_file  > tmp 
awk  '{ gsub(/Fax:/, ""); print $0}' tmp
