# 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.
