I'm not picking on Ciaran alone, alot of folks need to read up on xargs.
You do NOT want to spawn an instance of perl for EACH file, using xargs
will save a lot of processing time by spawning ONE perl instance (maybe
a couple if there are a LOT of files)..
Here's a handy line I like to use, this handles those pesky files with
spaces and other nasties in the filename:
find -type f -name '*.html' -print0 | xargs --null perl -pi -e
's/find/replace/'
All assumes normal GNU versions, double check your local man pages! And
don't forget to backup before doing any mass replace operation!
