Key Points

script cmdhist.log

This starts the script recording process, which underlyingly is spawning a new shell, all successive cmds you type is in the new shell.

exit

This exits the new shell created by script cmd.

script --timing=time.log cmdhist.log

This will populate another time.log file that keeps the timestamp of each historical cmd step. 

To replay such cmdhist.log, you need time.log and scriptreplay cmd.

scriptreplay --timing=time.txt script.log
