Well.
He already has a working Perl script. Less manpower to fix that than to
write a whole new script.
If you're going to use a shell script, I think you will find this model
both faster and safer: faster because the cat command is superflous, and
safer because it keeps the original, "just in case."
mv ${file{ ${file}~
sed <${file}~ >${file} \
-e "s/ *$//"
I've not tested mine either, but your sed's wrong;-)
