20 Jan 2008 Using GNU screen’s multiuser feature

Sometimes it’s useful to let someone see what you are doing in a console sessison. GNU screen is the tool for the job and lets a remote user follow on-screen what you are doing, great feature when you try to explain something over the phone.

To share your session you must start screen on the command line. Then enter

^A:multiuser on

That is, type Ctrl-A to enter the command mode, then type : to enter the screen’s build-in command line. You can now activate the multiuser mode by entering multiuser on in the screen’s command line that appears in reverse color at the bottom of the console window. To execute, hit Return.

The other person just have to log in with the same username, type

screen -x

to connect to your screen session running in multiuser mode and follow what you do.

09 May 2007 Using GNU screen

If you do not like unnecessary windows open, or want to get the maximum out of your terminal session, screen will soon be in your .bash_history numerous times. I found GNU Screen’s barrier to entry quite high, and I wanted to lower it for my readers.

GNU Screen enables you to run many shell processes in a single terminal. So in one e.g. xterm you can have many bash instances like layers in GIMP or Adobe Photoshop. Even better, you can split your terminal into different regions. Only Ratpoison gives you more bang for your bash!
