pam: Print something when fingerprint was successfully detected
Imagine you are using sudo
to start a long-running silent process, like in this example:
~ $ LANG=C sudo sleep 10
Place your right index finger on the fingerprint reader
After tapping the fingerprint reader, it seems there is no easy way of knowing if the process was started, or if the finger just wasn’t detected.
It might help if it printed
~ $ LANG=C sudo sleep 10
Place your right index finger on the fingerprint reader
Finger successfully recognized
or something like that.
