No, there's a difference ;-)

# ls -l x -rw-r--r-- 1 root root 0 Jan 27 20:07 x # chmod u+s x # ls -l x -rwSr--r-- 1 root root 0 Jan 27 20:07 x # chmod u+x x # ls -l x -rwsr--r-- 1 root root 0 Jan 27 20:07 x

See, e.g. http://www.linuxnix.com/2011/12/suid-set-suid-linuxunix.html

You see the difference more clearly

  • Capital S: chmod 4655 (no execute)
  • small s: chmod 4755 (execute set)

For when you would need capital S? Good question...
