# 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-hash 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;
