You have to export the variable if you want perl to recognize it!
Example:
$ ABC=xyz
$ perl -e 'print "$ENV{ABC}\n"'
$ export ABC=xyz
$ perl -e 'print "$ENV{ABC}\n"'
xyz
$

In awk you could use ENVIRON["varname"], is there something
compatible in perl.
You can do the same in perl with the special hash named %ENV.
for instance: print $ENV{'
Thanks Errin/Jim/David,
Hi Willy,
Perl will auto-magically take all of your shell environment variables and
put them in a hash:
%ENV
where the keys are the variable names and the values are the values!
so, for your example above,
# perl -e 'print "$ENV{ABC}\n"'
should work!
--Errin
You ca

You can do the same in perl with the special hash named %ENV.
for instance: pr
$ENV{"ABC"}
This works for me, but I don't have a good understanding of what is
going on to make it work.
