Global key press event emitter.

NOTE: requires sudo privileges.

Supports only Linux right now. Patches for Mac OS and Windows welcome!

The program outputs lines to stdout of either the form

pressed <KEY>

or

released <KEY>

It can be used to pipe keypress info into another program, which can capture whatever keys it is interested in.

This approach avoids writing key presses to a logfile, which has worse security properties.

git clone https://github.com/hackergrrl/global-keypress

# sudo bin/globalkeypress

Play a sound effect when the right shift key is pressed.

#!/bin/bash

IFS="\n"
sudo globalkeypress | while read line; do
  if echo $line | grep -q "pressed <RShift>"; then
    aplay -q sfx.wav
  fi
done
