NAME
 pam_echo — Echo PAM module
SYNOPSIS
 [service-name] module-type control-flag pam_echo [arguments]
DESCRIPTION
 The echo service module for PAM displays its arguments to the user, separated by spaces, using the current conversation function.
If the % character occurs anywhere in the arguments to pam_echo, it is assumed to introduce one of the following escape sequences:
- 
%H
- 
The name of the host on which the client runs (PAM_RHOST).
- 
%s
- 
The current service name (PAM_SERVICE).
- 
%t
- 
The name of the controlling tty (PAM_TTY).
- 
%U
- 
The applicant's user name (PAM_RUSER).
- 
%u
- 
The target account's user name (PAM_USER).
Any other two-character sequence beginning with % expands to the character following the % character.
