The following is an example of the wpm.d script.

This script takes the name of a program to trace, and assumes that reads

on file descriptor zero (STDIN) are keystrokes.

When run, a 5 second count down begins before keystrokes are measured,

# wpm.d vim

Measuring will start in : 5 seconds

While running, I retyped the first three sentences of this file a few times

which clocked the following result,

# wpm.d vim

Measuring will start in : 0 seconds

Measuring will stop in : 0 seconds

Characters typed : 509

Words per minute : 84

Minimum keystroke latency : 12 ms

Average keystroke latency : 118 ms

Maximum keystroke latency : 493 ms
