I like the subject :) I felt that way about users yesterday ... I created a directory with the same permissions: kepler:~ $ mkdir test kepler:~ $ /bin/ls -ldF test drwxr-s--- 2 nnorman nnorman 1024 Oct 30 11:20 test/ kepler:~ $ chmod 1700 test kepler:~ $ /bin/ls -ldF test drwx-----T 2 nnorman nnorman 1024 Oct 30 11:20 test/ So, it's a directory, accessible only by the owner, who can also create/delete files there. The "sticky" bit is also set (which in this case doesn't do much at all) However, the sticky bit is useful - consider the /tmp directory: kepler:~ $ whoami nnorman kepler:~ $ /bin/ls -ldF /tmp drwxrwxrwt 3 root root 1024 Oct 30 11:25 /tmp/ kepler:~ $ /bin/ls -lF /tmp total 44 drwxr-xr-x 2 root root 12288 Sep 25 18:17 lost+found/ -rw-r----- 1 root root 0 Oct 30 11:25 try_to_delete_me -rw-r--r-- 1 nnorman nnorman 31453 Oct 28 14:26 zman03143aaa kepler:~ $ rm /tmp/try_to_delete_me rm: remove `/tmp/try_to_delete_me', overriding mode 0640? y rm: /tmp/try_to_delete_me: Operation not permitted Although I can write to /tmp, which normally means I can delete any file within /tmp no matter who owns it, the sticky bit prevents me from deleting a file I don't own.
