For more utility, enable (and save) timings using the '-t' or '--timings <file>' option.

You can then replay the session, in realtime, or with some multiplier (slower or faster), using scriptreplay(1). An advantage is that full-screen utilities will be fully captured.

I've used this technique, and serial connections (zmodem, minicom, serial-over-ethernet, many ILOM/IPMI/BMC systems) to record full system installs, starting at BIOS prompts and configuration utilities.

Replaying the session through the phosphor(6x) screensaver can be entertaining.

On macOS and BSD at least (I haven't checked GNU), you can make a replayable script.

Record with

    script -r [filename]

and then play back with

    script -p [filename]

which creates a pretty cool effect.

Add timings.

With iTerm there is also an alternative approach.

You can enable 'Automatically log session input to files' in Preferences -> Profiles -> Session
