The user will lose sudo permission after 5 minutes without using it.

Most computers will take more than 5 minutes to compile bitcoin, so we need a step that prompts the user for a password again.

  Compiling source code, please wait... ok.
  Running compile checks, please wait... ok.
  Installing Bitcoin Core... Password:

Another approach would be to keep sudo alive, so we don't need to check for it.

keep_sudo_alive() {
    while true; do
        sudo -n true
        sleep 60 # Adjust the sleep time as needed
    done
}

keep_sudo_alive &
keep_sudo_alive_pid=$!
make
kill "${keep_sudo_alive_pid}"
