The script command doesn't record timing data, so it's not very useful for playback. It's designed for transcripts, not for videos.

Per the man page, `script -t` captures timing data which you can playback easily with `scriptreplay -t`

Yes but script command on *BSD and macOS doesn't support this. Long long time ago asciinema was wrapping script then doing upload. But it work only on Linux and I wanted it to work for users of other Unix-like systems so here we are.

on linux it is does have timing recording try with

script -tshell_recording.time shell_recording.script bash

scriptreplay -t shell_recording.time shell_recording.script
