Hello all,

Hello,

How do you print elements of an array, each on its own
line, in a Windows' console?

I'm doing the following:

E:\My Documents>perl -e "use
ExtUtils::Installed; my $inst =
ExtUtils::Installed->new(); my @modules =
$inst->modules(); print @modules"

it returns:


Archive::TarArchive::ZipArray::CompareAutoLoaderCPANCPAN::ChecksumsCPAN::DistnameInfo
...etc.

I need:

Archive::Tar
Archive::Zip
Array::CompareAutoLoaderCPAN
CPAN::Checksums
CPAN::DistnameInfo ...etc.

I tried "\n", '\n' and a
'foreach' loop, but nothing I do seems to work.
..any suggestions?

I don't have Windows to test this on but this should
work:

perl -MExtUtils::Installed -le"my $inst =
ExtUtils::Installed->new(); print for
$inst->modules()"

Thanks, John. It does work. And, I've found that my original command also works when I added the -l and 'for' like:

perl -le "use ExtUtils::Installed; my $inst = ExtUtils::Installed->new(); my @modules = $inst->modules(); print for @modules"

I don't know if mine is correct form though. 'perl -h' reveals that -l enables line ending processing, specifies line terminator. Is that the idea?
