Having something to this extent would be useful in case of searching for directories with too many files, for example.

No need to ignore anything. -- With best regards, Andrey Repin Thursday, November 1, 2018 19:00:26 Sorry for my terrible english... -- 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
