PAM_GETENV(8)         User Contributed Perl Documentation        PAM_GETENV(8)

NAME
       pam_getenv - get environment variables from /etc/environment

SYNOPSIS
       pam_getenv [-l] [-s] env_var

DESCRIPTION
       This tool  will print out the value of env_var from /etc/environment.
       It will attempt to expand environment variable references in the
       definition of env_var but will fail if PAM items are expanded.

       The -l option indicates the script should return an environment
       variable related to default locale information.

       The -s option indicates that the script should return an system default
       environment variable.

       Currently neither the -l or -s options do anything.  They are included
       because future versions of Debian may have a separate repository for
       the initial environment used by init scripts and for system locale
       information.  These options will allow this script to be a stable
       interface even in that environment.

       with the handle pamh for an item that matches the string pointed to by

       The application is not allowed to free the data.

RETURN VALUES
