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

I have found the following perl script online to convert a msg file saved from Outlook into a mime file.

#!/usr/bin/perl -w
use strict;
use warnings;

use Email::Outlook::Message;
use Email::LocalDelivery;
use Getopt::Long;
use Pod::Usage;
use File::Basename;
use vars qw($VERSION);
$VERSION = "0.903";

my $verbose = '';
my $mboxfile = '';
my $help = '';
GetOptions(
  'mbox=s' => \$mboxfile,
  'verbose' => \$verbose,
  'help|?' => \$help) or pod2usage(2);
pod2usage(1) if $help;

defined $ARGV[0] or pod2usage(2);

foreach my $file (@ARGV) {
  my $mail = new Email::Outlook::Message($file, $verbose)->to_email_mi
+me->as_string;
  if ($mboxfile ne '') {
    Email::LocalDelivery->deliver($mail, $mboxfile);
  } else {
    my $basename = basename($file, qr/\.msg/i);
    my $outfile = "$basename.mime";
    open OUT, ">:utf8", $outfile
      or die "Can't open $outfile for writing: $!";
    print OUT $mail;
    close OUT;
  }
}

It is working good, and a huge THANK YOU to the author. The reason I am posing here is that if I want to use this script, I need to initiate it by entering the following:

$ perl ./msg.pl *msg

What I am trying to accomplish is scan the entire directory for msg files, and parse them accordingly.

my @mimefiles = <*.mime>;
foreach my $mimefile (@mimefiles) {
foo....
}

As a novice perl programmer, could someone offer a suggestion at how I would go about accomplishing my goal of not having to enter the ' *msg'? Thank you for your time.

    Your problem is that the script is made to only accept literal file names instead of file globs?

    If so, just add a filter to the @ARGV loop to translate any globs into a list of files like you already demonstrated in your second bit of code:

    foreach my $file (map {/\*/ ? glob($_) : $_} @ARGV) {

    I think you could try something like this, depending on how you want to specify the directory:

    #!/usr/bin/perl -w
use strict;
use warnings;

use Email::Outlook::Message;
use Email::LocalDelivery;
use Getopt::Long;
use Pod::Usage;
use File::Basename;
use vars qw($VERSION);
$VERSION = "0.903";

use File::Slurp;  # exports read_dir sub

my $verbose = '';
my $mboxfile = '';
my $help = '';
GetOptions(
  'mbox=s' => \$mboxfile,
  'verbose' => \$verbose,
  'help|?' => \$help) or pod2usage(2);
pod2usage(1) if $help;

defined $ARGV[0] or pod2usage(2);

my $dir = $ARGV[0];  # pass in directory instead of file

foreach my $file ( read_dir( $dir ) ) {

   next unless $file =~ /\.msg/;  # skip anything that is not a messag
+e
   $file = $dir .'/' . $file;     # Email::Outlook::Message, does it r
+equire fully qualified path?

  my $mail = new Email::Outlook::Message($file, $verbose)->to_email_mi
+me->as_string;
  if ($mboxfile ne '') {
    Email::LocalDelivery->deliver($mail, $mboxfile);
  } else {
    my $basename = basename($file, qr/\.msg/i);
    my $outfile = "$basename.mime";
    open OUT, ">:utf8", $outfile
      or die "Can't open $outfile for writing: $!";
    print OUT $mail;
    close OUT;
  }
}
