# How are r-- directory permissions supposed to work on Linux?

view story

http://serverfault.com – I have created directory a created has these permissions - the other user has drwxr--r-- 5 user user 4096 2012-09-15 19:30 sites When do an ls -l on the directory as another user ls -l /home/user/sites this is the directory output. I thought without the x bit set on that directory the filenames wouldn't show at all. d????????? ? ? ? ? ? dev.user.com -????????? ? ? ? ? ? user.20120914_082804.sql.gz d????????? ? ? ? ? ? shared -????????? ? ? ? ? ? shared.tar.gz -????????? ? ? ? ? ? www.20120914 (HowTos)
