advanced file permissions in linux

There are 3 advance file permissions available in Linux:

1) SUID 

2) SGID

3) STIKIBIT.

Set-user-ID: It provides administrator privileges to normal users to run administration commands.

Set-group-ID: It provides Group ID - Hierarchy on executable command.

Stick Bit: It restricts others to removing the data on the Stick-bit applied recourse expect owner.

NOTE: I will explain practical in next post.
