Sharing a Screen Session With Other System Administrators

written

Create a named screen session:

steve@machine:~$ screen -S lhm

Or, name your existing session:

Ctrl-a :sessionname lhm

Turn on screens multi user mode and give access to the root user:

Ctrl-a :multiuser on
Ctrl-a :acladd root

Now any admin user can attach to this screen session with the following command:

sudo screen -x steve/lhm

This is useful when you want to give other admin users the ability to view and control a long running task that you started.
