But try for yourself > and surprise me. :-) A traditional way of stripping CRs is with col(1): % col < config.php > config.php-lfonly sed almost goes out of its way to make the most useful escapes unavailable, or at least unavailable where you need them. Perl makes it all available and can be used as a sed replacement: % perl -i.bak -pe 's/\r//g' config.php (Tested.)
