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.
