Env(3) — IRIX 6.5.3f



Env(3)                                                                  Env(3)



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;
