s permission on directories make up for the following behaviour: $ ls -ld test drwx------ 2 jens jens 1024 Sep 30 10:16 test $ cd test $ su Password: # mkdir test2 # exit exit $ chmod g+s . hilbert [~/test] $ su Password: # mkdir test3 # exit exit $ ls -la total 8 drwx--S--- 4 jens jens 1024 Sep 30 10:19 . drwx------ 46 jens jens 5120 Sep 30 10:16 .. drwxr-xr-x 2 root root 1024 Sep 30 10:17 test2 drwxr-sr-x 2 root jens 1024 Sep 30 10:19 test3 The uppercase letter indicates that the group x right is not set. All files and directories created in a directory with group s set, will automatically set the group to the group of the parent directory.
