Use the %ENV hash to access environment variables. Environment variables will not normally become Perl variables (unless you write some code to do so) magically. But note that, because perl is executed as a process, you cannot change the corresponding environment variable in the shell from Perl, because what you will get from Perl is just a copy:

Code:
$ ( export TEST="me"; perl -e 'print $ENV{"TEST"}, "\n"'; )
me
$ echo $0
ksh

asadmin-export(1AS)						   User Commands					       asadmin-export(1AS)

NAME
asadmin-export, export - marks a variable name for automatic export to the environment of subsequent commands in multimode SYNOPSIS
export [ name=value [ name=value]*] Marks a variable name for automatic export to the environment of subsequent commands. All subsequent commands use the variable name values as specified; unless you unset them or exit multimode. If only the variable name is specified, the current value of that variable name is displayed. If the export command is used without any arguments, a list of all the exported variables and their values is displayed. Exported shell environment variables set prior to invoking the asadmin utility are imported automatically and set as exported variables within asadmin. Unexported environment variables cannot be read by the asadmin utility. OPERANDS
name=value variable name and value for automatic export to the environment to be used by subsequent commands. Example 1: Using export to list the 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 //to list the environment variables that are set AS_ADMIN_HOST=bluestar AS_ADMIN_PORT=8000 AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=******** AS_ADMIN_PREFIX=server1.jms-service Where: the export command lists the environment variables that are set. In this case, the environment variables have been set to: the host is bluestar, the port is 8000, the administrator user is admin with an associated password, and the prefix is server1.jms-service. EXIT STATUS
0 command executed successfully 1 error in executing the command asadmin-unset(1AS), asadmin-multimode(1AS) J2EE 1.4 SDK March 2004 asadmin-export(1AS)
