    Create the Collaborative Area

    First, we need to create the directory:

    mkdir /opt/managers

    Then we set it so that all new files created will be owned by the managers group:

    chmod g+s /opt/managers

    Create a Scratch Area, Similar to /tmp, Named scratch

    First create the directory:

    Then set the Sticky Bit:

    chmod o+t /opt/managers/scratch
