#requires zsh:
dos2unix **/*.{cpp,c,h}

#requires enhanced find, xargs and perl
find . -type f -name "*.[ch]" -o -name \*.cpp -print0 |
xargs -0 PERL -npi.bak -e 's/.$//o'

#might blow up on larger directories or files with spaces in
for i in `find . -type f -name "*.[ch]" -o -name \*.cpp`
do
sed 's/.$//' "$i" > "$i".tmp && mv "$i".tmp "$i"
done
