====== Create And Configure Set-gid Directories For Collaboration ======

**General Information**

Team collaboration directories. 

----

===== Scenario =====

When files are created in a directory with set-GID, the new files inherit the group ownership of that directory.

**Example scenario**: The IT department would like to have a directory for its shared scripts amongst team members in /home/. They want the directory called "shared-scripts" and their group name to be "it". All files created should be owned by "it" and no other users are allowed access. Add two of the members "rjones" and "dvader" to the group for them to test. Add them so that the "it" group is not their primary group.

----

===== Solution =====

Create the group "it"
<code bash>
groupadd it
</code>

\\
Create rjones and dvader
<code bash>
useradd rjones
useradd dvader
</code>

\\
Add the "it" group as a supplementary group
<code bash>
usermod -aG it rjones
usermod -aG it dvader
</code>

\\
Create the "shared-scripts" directory
<code bash>
mkdir /home/shared-scripts
</code>

\\
Change ownership
<code bash>
chown root:it /home/shared-scripts
</code>

\\
Change the group set-GID bit so all files created will be owned by "it"
<code bash>
chmod g+s /home/shared-scripts
chmod g+w /home/shared-scripts
</code>
  * Also give them write access

\\
Remove Permissions from all others
<code bash>
chmod o-rwx /home/shared-scripts
</code>
