Make and play transcripts of terminal sessions

This is great for teaching programming or Unix usage, for producing "live" documentation for some common tasks. You may also want to make a transcript of a terminal session if you are planning to develop a script to automate the task later on.

It is advisable to save timing information along with the transcript so that you can reply it.

$ script -t transcript.txt

Play (you better use the same type of terminal you recorded from):
$ scriptreplay -t transcript.txt

scriptreplay can't do without a timing file. If you have forgot the -t option, an acceptable way to display the script could be by disabling printing of raw control characters in less using the usual caret notation (e.g. ^C):

$ less -r transcript.txt

but this won't work well with programs who clear the screen like vi(1).
