Hi.

The "s" designates that file/dir as "sticky" and is called the sticky 
bit.  The sticky bit makes sure that Users in a group must have write 
access to a directory and must own a file, or be root, to unlink/remove 
it if it is sticky.  You can set sticky with a "1" preceeding the normal 
file access mask like so: chmod 1755 file.txt


Take care.
