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 [1] , 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[=DEVICE]
Ask question on TTY DEVICE instead of querying the user on the calling TTY. If DEVICE is not specified, /dev/console will be used.
−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.
