Every directory in the path must have the +x bit for you. Not necessarily the +r bit. The +r bit allows you to *read* the directory, in order to see the names of the files. The +x bit allows you to *access* the files in the directory, if you know their names. You also need the appropriate bits on the file itself, if you plan to open it (in either read only or read+write mode). unicorn:~$ mkdir /tmp/x unicorn:~$ echo stuff > /tmp/x/file1 unicorn:~$ chmod 100 /tmp/x unicorn:~$ ls -ld /tmp/x d--x------ 2 greg greg 4096 Sep 1 10:34 /tmp/x/ unicorn:~$ ls /tmp/x ls: cannot open directory '/tmp/x': Permission denied unicorn:~$ cat /tmp/x/file1 stuff
