Read UNIX environment variable

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

In unix I have an env variable like this

NOTEUSERS="
    me@us.com \
    them@us.com\
" export NOTEUSERS
[download]

Yes there are spaces at the front. I can read this using

use Env;
my @noteusers = $NOTEUSERS;
[download]

How can I split this up so that each entry of @noteusers array is just the email address without spacing etc. Thanks

like this? `use Env; my $n = $ENV{'NOTEUSERS'}; for (split /[\s\n]/, $n) {print "key: \"$_\"\n" if ($_)}` [download] Can you improve this and show here your result?	[reply] [d/l]

An obvious improvement is to notice that \s contains \n. And also that 'use Env' is completely useless in this case.	[reply]

Thanks, will I be able to access env variables if my perl code gets run from cron?	[reply]
