Based on a cursory glance at Env.pm, it appears that it will skip
any names in the environment that dont match [A-Za-z_].
You could get at it through the regular %ENV hash:
$ENV{'!EXITCODE'}
This command works on my (HPUX) system:
$ env !EXITCODE=hello perl -e 'print $ENV{q[!EXITCODE]}, "\n"'
hello
Is this variable some artifact of your shell? Are you wanting to
test it following the ls backticks? If so, this isn't going to
work. The shell/ls will be executed in a child process, and the
child cannot affect the parent's environment. If you just want
the exit status from the backtics, you can use Perl's regular
$? variable. Or maybe I'm misunderstanding the whole issue.
(Wouldn't be the first time).
