How to set the SUID ,SGID and Sticky Bit

Ram-Ram to All bhai jis I am Deepak Saini again and try to explain the SUID (super user id or set user id )

SUID / Set User ID :
A program is executed with the file owner's permissions (rather than with the permissions of the user who executes it).

SGID / Set Group ID : Files created in the directory inherit its GID, i.e When a directory is shared between the users , and sgid is implemented on that shared directory , when these users creates  directory, then the created directory has the same gid or group owner of its parent directory.

Sticky Bit :  It is used mainly used on folders in order to avoid deletion of a folder and its content by other user though he/she is having write permissions. If Sticky bit is enabled on a folder, the folder is deleted by only owner of the folder and super user(root). This is a security measure to suppress deletion of critical folders where it is having full permissions by others.

Permissions                      Description 
     0                                   nothing
     1                                   Sticky Bit
