I believe this will do what you want.
#!/usr/local/bin/perl
use MIME::Parser;
use strict;
use warnings;
## directory to store all parsed MIME parts
my $outputdir = "./mimemail";
my $parser = new MIME::Parser;
$parser->output_dir($outputdir);
## this creates files for all parts
my $entity = $parser->read(\*STDIN);
my $num_parts = $entity->parts;
## define attachment types to keep -- notice all lowercase
## add as many types as you like.
my %type_ok = (
'application/octet-stream' => 1
);
if ($num_parts > 0) {
for (my $i = 0; $i < $num_parts; $i++) {
my $part = $entity->parts($i);
## note: lc so types have a better chance of matching
my $type = lc $part->mime_type;
my $bh = $part->bodyhandle;
## delete parts we don't want
if (! exists $type_ok{$type}) {
my $status = system("rm '$bh->{MB_Path}'");
die $! unless $status == 0;
}
}
}
The program is executed like this:
program < single.message.mime
Update: './mimemail' directory should already exist. Also removed unneeded 'my $msg_body;' line.
