The code is as follows:
Amosli@amosli-pc:~/learn$ script-T2 > timing.log-an output.session# starts recording
Script started, file is output.session
Amosli@amosli-pc:~/learn$ hello1
No command 'hello1' found, did you mean:
Command 'hello' from package' hello-debhelper' (main)
Command 'hello' from package' hello' (main)

Exit # end recording
Script done, file is output.session
Play the recording:
The code is as follows:
Amosli@amosli-pc:~/learn$ scriptreplay timing.log output.session # output by playback command sequence
Amosli@amosli-pc:~/learn$ hello1
No command 'hello1' found, did you mean:
Command 'hello' from package' hello-debhelper' (main)
Command 'hello' from package' hello' (main)

Conduct a broadcast video session between multiple users: open two terminals
(1) enter the following command in Terminal 1:
The code is as follows:
Mkfifo scriptfifo
(2) enter the following command in Terminal 2:
The code is as follows:
Cat scriptfifo
(3) return to Terminal 1 and enter the following command:
The code is as follows:
Script-f scriptfifo
Commands...
In this way, the role of broadcasting and online classes is realized, which is very magical!
The output of my own experiment:
The code is as follows:
Terminal 1:
Amosli@amosli-pc:~$ mkfifo scriptfifo
Amosli@amosli-pc:~$ script-f scriptfifo
Script started, file is scriptfifo
Amosli@amosli-pc:~$ who
