Question

In my ubuntu 14.04 lts, I tried setgid command as root user but it give setgid not found, for setuid it says to install and I install . But for setgid it does not give any option. So how can I get this command in linux ubuntu 14.04 LTS

Answer 1

When the setgid bit is set on a directory, new sub folders and files within that directory will inherit the group of the owner of the directory. If you do this on a folder, you can force new files and folders to have your group id, even if another user does the creation.

You can turn the setgid bit on by running:

chmod g+s <directory name here>

The user and group can be displayed using in the parent directory.

ls -l
