There are two possibilities for newly created subdirectories and files in this directory. 1. Same group as the creator. 2. Same group as the parent directory. If my memory is correct this is a bsd vs sysV distinction. Nowadays you get to choose the behavior you want. Since you want behavior 2 you want the set-group-ID bit set on the parent and then newly created subdirectories and files in this directory will inherit the group from the parent. So you want to chmod +2000 parent-directory The full story is in the info page Node: Directory Setuid and Setgid I just read it to check my memory and found out that apparently some systems use the set-user-ID bit so the page suggests chmod +6000 parent-directory which sets both. Also this is a gnu extension and not required by POSIX. allan gottlieb new york university -- [EMAIL PROTECTED] mailing list
