Re:x2 Shell/Perl Variables

Depending on whether the environment variables are exported or not, your suggestion might not work:

% FOO=bar
% echo $FOO
bar
% perl -le 'print shift' $FOO
bar
% perl -le 'print $ENV{FOO}'

In the original example, the shell script was called from elsewhere, and the variables were setup outside of the shell. So, whether the shell exports variables or not is irrelevant. -- Abigail	[reply]
