I couldn't resist trying it out on my Linux box, which runs the same version of pdksh as my Cygwin install. Even more interestingly, it works as you were expecting on Linux as well. So this looks like a problem with the Cygwin port of pdksh. This simpler test case demonstrates it pretty clearly: --test.sh-- dos2unix foo.txt while read x; do echo "$x"; done < foo.txt unix2dos foo.txt while read x; do echo "$x"; done < foo.txt --foo.txt-- 1 2 3 ---- Run under various shells: $ sh test.sh # zsh and bash yield same result foo.txt: done. 1 2 3 foo.txt: done. 1 2 3 $ ksh test.sh # this one fails for DOS endings foo.txt: done. 1 2 3 foo.txt: done. 1 $ _ gsw -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
