The second part is a little harder than the first, but assuming all of
the occurrences of .html want to be converted to .php...

find . -name "*.html" -exec ./doit.sh \{\} \;

Where doit is a script contining


#!/bin/sh -

cat $1 | sed -e "s/\.html/\.php/g" > /tmp/fixing
mv /tmp/fixing $1

mv $1 `echo $1 | sed -e "s/html$/php/"`

You caught me in between jobs {:-) Shell scripting is fun and it sounded
like a good 5 minute challenge and indeed it was {:-)

sed is your friend. Others may do it with awk, but I find sed easier.

Duncan did some good perl talks, I dunno if the notes from that are
still available?
