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.

NAME

       asadmin-unset, unset - removes one or more variables from the multimode environment

SYNOPSIS

       unset env_var [env_var]*

       Removes	one or more variables you set for the multimode environment. The variables and their associated values will no longer exist in the
       environment.

OPERANDS

       env_var		       environment variable to be removed.

       Example 1: Using unset to remove environment variables

       asadmin> export AS_ADMIN_HOST=bluestar AS_ADMIN_PORT=8000 AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=password
       asadmin> export AS_ADMIN_PREFIX=server1.jms-service
       asadmin> export
       AS_ADMIN_HOST=bluestar
       AS_ADMIN_PORT=8000
       AS_ADMIN_USER=admin
       AS_ADMIN_PASSWORD=********
       AS_ADMIN_PREFIX=server1.jms-service
       asadmin> unset AS_ADMIN_PREFIX
       asadmin> export
       AS_ADMIN_HOST=bluestar
       AS_ADMIN_PORT=8000
       AS_ADMIN_USER=admin
       AS_ADMIN_PASSWORD=********

       Using the export command without the argument lists the environment variables that are set. Notice the AS_ADMIN_PREFIX is not in the  envi-
       ronment after running the unset command.

EXIT STATUS
