       pam_getenv - get environment variables from /etc/environment


       pam_getenv [-l] [-s] env_var


       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.
