Unix Tip #4292- December 11, 2012
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'
NOTE: All tips provided are USE AT YOUR OWN RISK. Tips are submitted

test each tip in a non-volitile environment before placing into
