If a file is SGID, it will run with the privileges of the files group owner, instead of the privileges of the person running the program.

If a directory is SGID, it will inherits the privileges of the directory group owner.

Sticky Bits:
If the sticky bit is set for a directory, only the owner of that directory or the owner of a file can delete or rename a file within that directory.
