This use of '@' in a mode string conflicts with the use of '@' on MacOS X 10.5 and newer to designate "extended attributes" (like quarantine information on MacOS X 10.7). $ /bin/ls -l /etc/ntp.conf -rw-r--r--@ 1 root wheel 27 Apr 5 2008 /etc/ntp.conf $ /bin/ls -l@ /etc/ntp.conf -rw-r--r--@ 1 root wheel 27 Apr 5 2008 /etc/ntp.conf com.apple.TextEncoding 15 You can see that both in the mode string (-rw-r--r--@) as well as among the '/bin/ls' command-line option, the '@' has the meaning "extended attributes". Having GNU coreutils interpret "@rw-r--r--" in a completely different way would be counterintuive and confusing. Bruno
