Here 'S' denotes what?
Sticky bit.
The file permissions bits include an execute permission bit for file
owner, group and other. When the execute bit for the owner is set to "s"
the set user ID bit is set. This causes any persons or processes that
run the file to have access to system resources as though they are the
owner of the file. When the execute bit for the group is set to "s", the
set group ID bit is set and the user running the program is given access
based on access permission for the group the file belongs to. The
following command:
chmod +s myfile
sets the user ID bit on the file "myfile". The command:
chmod g+s myfile
sets the group ID bit on the file "myfile".
