FIND/REPLACE RECURSIVELY 
Find and replace recursively
 through an entire directory
 tree using the following command:
 
 $ grep -rlZ pattern /some/dir | xargs -r0 perl -pi -e 's/pattern/replacement/g'
 
 
 If the word CAT was to be replaced
 with the word DOG in all files
 starting at the top of /home/kennel
 and all subdirectories below it:
 
 $ grep -rlZ CAT /home/kennel | xargs -r0 perl -pi -e 's/CAT/DOG/g'
