scriptreplay ? play back typescripts, using timing information

s c r i p t r e p l a y timing?le[typescript[divisor]]

D E S C R I P T I O N

This program replays a typescript, using timing information to ensure that output happens at the same speed as it originally appeared when the script was recorded.

The replay simply displays the information again; the programs that were run when the typescript was being recorded are not run again. Since the same information is simply being displayed,s c r i p t r e p l a y is only guaranteed to work properly if run on the same type of terminal the typescript was recorded on.Oth-erwise, any escape characters in the typescript may be interpreted differently by the terminal to which s c r i p t r e p l a y is sending its output.

The timings information is what s c r i p t(1) outputs to standard error if it is run with the?t parameter.

By default, the typescript to display is assumed to be named ‘‘typescript’’, but other ?lenames may be spec-i?ed, as the second parameter.

If the third parameter is speci?ed, it is used as a speed-up multiplier.For example, a speed-up of 2 makes s c r i p t r e p l a y go twice as fast and a speed-up of 0.1 makes it go ten times slower than the original session.
