Script: Visulizzare una sessione in tempo reale su due macchine

This little trick allows you to share your terminal session with other users. For example, it could be helpful for making remote demos of GNU/Linux to your unexperienced users or to capture what you do in a session.

For this trick to work we will use these system utilities:

• script: to dump everything we type on the terminal to a file
• mkfifo: to create a FIFO (named pipes)

We want that everything typed in on hostA to be reflected in a session opened from hostB. Here we go...

From hostA issue these commands:

    cd /tmp
    mkfifo funforme; script -f funforme

And from hostB...

    ssh user@hostA
    cd /tmp
    cat funforme

Now everything you type on hostA will be reflected in hostB. Funny, isn't it? To exit the session, simply type exit from hostA and CTRL+C from hostB. You could also delete the named pipe funforme.
