Stupid Linux Trick #5245 Posted on 2009-08-18

Want to share what you're doing with another person logged into the same system? All you need is a FIFO, cat, and script. On your session:

    mkfifo foo
    script -f foo

On the viewer's session:

    cat foo

The viewer can then see everything that you're doing as if they're looking over your shoulder!
