yes.

the first way used a loop in bash for each file matching *.html.
The second way is better.

perl -wpi.bak -e 's/foo/bar/g' *.html

does exactly the same thing and is far easier to type :-).
(i just used * because i realised there may files other than html files)


I'm not sure exactly why i thought there for loop was needed.
I've spent all evening trying to find a bug in efsd and I think its
fried my brain :-)
