To broadcast video sessions between multiple users: open two terminals

(1) In Terminal 1, enter the following command:

Copy Code code as follows:

Mkfifo Scriptfifo

(2) in Terminal 2, enter the following command:

Copy Code code as follows:

Cat Scriptfifo

(3) Return to Terminal 1 and enter the following command:

Copy Code code as follows:

Script-f Scriptfifo
Commands ...

This is the realization of the broadcast, online classroom class role, very magical!!

The output of my own experiment:

Copy Code code as follows:

Terminal 1:
amosli@amosli-pc:~$ Mkfifo Scriptfifo
amosli@amosli-pc:~$ script-f Scriptfifo
Script started, file is Scriptfifo
