Permissions Question

[Keith Johnson]

This is fairly simple probably, but I'm in a time crunch. What are the chmod parameters necessary to set permissions on a file to

-r-s--S---

I've browsed the man pages for chmod but haven't been able to find the right combination. Thanks!

Keith,
search for 'sticky bit' ans set user id
example:

man chmod
"Assign read and execute permission to everybody, and set the set-user-ID bit:

chmod a=rx,u+s file"

So for you:
chmod u=r+s,g+s file

lower case s is setuid bit is set, 4 for 4th bit
capital S is sgid but execute is not set for gid. But that would be 2 for the 4th bit.

BTW, sticky bit is 1 for 4th bit, and represents a t. T if others execute is not set.
