NAME
       pam_issue - PAM module to add issue file to user prompt

SYNOPSIS

       pam_issue.so [noesc] [issue=issue-file-name]

DESCRIPTION
       pam_issue is a PAM module to prepend an issue file to the username prompt. It also by default parses escape codes in
       the issue file similar to some common getty's (using \x format).

       Recognized escapes:

       \d
	   current day

       \l
	   name of this tty

       \m
	   machine architecture (uname -m)

       \n
	   machine's network node hostname (uname -n)

       \o
	   domain name of this system

       \r
	   release number of operating system (uname -r)

       \t
	   current time

       \s
	   operating system name (uname -s)

       \u
	   number of users currently logged in

       \U
	   same as \u except it is suffixed with "user" or "users" (eg. "1 user" or "10 users")

       \v
	   operating system version and build date (uname -v)

OPTIONS
       noesc
	   Turns off escape code parsing.

       issue=issue-file-name
	   The file to output if not using the default.

       Only the auth module type is provided.

RETURN VALUES
