systemd-tty-ask-password-agent - List or process pending systemd password requests
SYNOPSIS
systemd-tty-ask-password-agent [OPTIONS...] [VARIABLE=VALUE...]
DESCRIPTION
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[1], and is one of many possible response agents which answer to
queries formulated with systemd-ask-password(1).
OPTIONS
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.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
