Thanks. I guess that the reason find opens the file (and thereby trigger antivirus) is because I print the files timestamp (-printf '%A+\n'), right? If I just printed the filename, the file would not be opened, right? Will find /xx -type f -iname "zzz" -mtime +10s -execdir 'msg * "Achtung programme crash boom!"' not open the file to get the timestamp? /Morten -- 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
