PAM_GETENV(8)             (2021-08-26)              PAM_GETENV(8)

          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
