How to record/playback terminal in Linux (using scriptreplay, ttyrec, TermRecord, asciinema, showterm)

It is useful to be able to rapidly share computer activity with a screencast, by recording and playback TTY output of a text-mode program.

$ script -t 2> timingfile
# script started, file is typescript
$ ls
<etc, etc>
$ exit
# script done, file is typescript
$ scriptreplay timingfile
  • ttyrec/ttyplay is a program and/or its file format capable of recording the TTY output of a text-mode program together with timestamps and then replaying it. similar to the script command, but also allows for pausing, slowing down or speeding up playback. ttycast broadcast your ttyrec in real time.
$ ttyrec
# in the executed shell, do whatever you want and exit
$ ttyplay ttyrecord

$ npm install -g ttycast
$ ttyreccast outfile.tty
# open browser to 'http://localhost:13377/'
$ reset && ttyrec /tmp/ttycast

  1. Can anyone with experience in these tools post how to avoid the automatic upload in each? (such as showterm) Use case: I wish to create a hand editable file (IOW, not a binary format and elegant text format) but I have no wish to upload some of these.
