This works because the current version of grep (2.6.3-1) doesn't treat its input as binary by default, but strips the carriage returns from the output of net localgroup. So grep -iq "^${username}$" matches, but grep --binary -iq "^${username}$" doesn't. > Do Windows tools output in DOS mode "when they want" ? No, od -c shows the \r\n endings in the output of net localgroup. --Dirk -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
