Explanation
The chmod command is used to change the permissions of files and directories on Linux systems.
The g+s option sets the setgid bit on a directory, which means that all files and folders created inside that directory will inherit the group name of the parent directory. This command can help the developer ensure that all files and folders created inside the /GroupOODEV directory have the same group name as
/GroupOODEV. References: [How to Use chmod Command in Linux with Examples]
