Env

NAME

Env - perl module that imports environment variables

SYNOPSIS

use Env; use Env qw(PATH HOME TERM);

DESCRIPTION

Perl maintains environment variables in a pseudo-associative-array named %ENV. For when this access method is inconvenient, the Perl module Env allows environment variables to be treated as simple variables.

The Env:: import() function ties environment variables with suitable names to global Perl variables with the same names. By default it does so with all existing environment variables ( keys %ENV ). If the import function receives arguments, it takes them to be a list of environment variables to tie; it's okay if they don't yet exist.

After an environment variable is tied, merely use it like a normal variable. You may access its value

@path = split(/:/, $PATH);

or modify it

$PATH .= ":.";

however you'd like. To remove a tied environment variable from the environment, assign it the undefined value

undef $PATH;
