systemd-tty-ask-password-agent [OPTIONS...] [VARIABLE=VALUE...]
systemd-tty-ask-password-agent is a password agent that handles password requests of the system, for example for hard disk encryption passwords or SSL certificate passwords that need to be queried at boot-time or during runtime. systemd-tty-ask-password-agent implements the Password Agents Specification, and is one of many possible response agents which answer to queries formulated with systemd-ask- password(1).
The following options are understood: --list Lists all currently pending system password requests. --query Process all currently pending system password requests by querying the user on the calling TTY. --watch Continuously process password requests. --wall Forward password requests to wall(1) instead of querying the user on the calling TTY. --plymouth Ask question with plymouth(8) instead of querying the user on the calling TTY. --console Ask question on /dev/console instead of querying the user on the calling TTY. -h, --help Print a short help text and exit. --version Print a short version string and exit.
On success, 0 is returned, a non-zero failure code otherwise.
