Thanks radoulov. For some reason I had to do small changes for it to work. You probably know the reason
If I want to put only the entries Email and Age in the output file from the desired record, how do I do that? I know 'print' command can do this, but my syntax always goes wrong.
I have a file which is 5 million records. And each records has 412 fields has delimited by "|". So that makes each records to be 2923 bytes long. I wanted to extract specific records like top 100 or 2500 - 5000, 50001 - 10000 etc. from this file.
I tried using head command for top 100 records,... (1 Reply)
I am trying to cut the first 10 characters from a file only if the file has 'xyz' in field 185-188.
I tried this

but this gives me all the records regardless of what is in field 185-188.
Is this doable ?
Thanks in advance for responses. (2 Replies)

email::foldertype
Email::FolderType(3pm) User Contributed Perl Documentation Email::FolderType(3pm)NAME
Email::FolderType - determine the type of a mail folder
SYNOPSIS
use Email::FolderType qw(folder_type);
print folder_type "~/mymbox"; # prints 'Mbox'
print folder_type "~/a_maildir/"; # prints 'Maildir'
print folder_type "some_mh/."; # prints 'MH'
print folder_type "an_archive//"; # prints 'Ezmlm'
DESCRIPTION
Provides a utility subroutine for detecting the type of a given mail folder.
SUBROUTINES
folder_type <path>
Automatically detects what type of mail folder the path refers to and returns the name of that type.
It primarily bases the type on the suffix of the path given.
Suffix | Type
--------+---------
/ | Maildir
/. | MH
// | Ezmlm
In case of no known suffix it checks for a known file structure. If that doesn't work out it defaults to "Mbox" although, if the "Mbox"
matcher has been overridden or the default changed (see DEFAULT MATCHER below) then it will return undef.
matchers
Returns a list of all the matchers available to the system.
DEFAULT MATCHER
Currently the default matcher is "Mbox" and therefore it is always checked last and always returns 1.
If you really want to change this then you should override "Email::FolderType::Mbox::match" and/or change the variable $Email::Folder-
Type::DEFAULT to be something other than 'Mbox'.
use Email::FolderType;
use Email::FolderType::Mbox;
$Email::FolderType::DEFAULT = 'NewDefault';
package Email::FolderType::Mbox;
sub match { return (defined $_[0] && -f $_[0]) }
package Email::FolderType::NewDefault;
sub match { return (defined $_[0] && $_[0] =~ m!some crazy pattern!) }
1;
REGISTERING NEW TYPES
"Email::FolderType" briefly flirted with a rather clunky "register_type" method for registering new matchers but, in retrospect that wasn't
a great idea.
Instead, in this version we've reverted to a "Module::Pluggable" based system - any classes in the "Email::FolderType::" namespace will be
interrogated to see if they have a c<match> method.
If they do then it will be passed the folder name. If the folder matches then the match function should return 1. For example ...
package Email::FolderType::GzippedMbox;
sub match {
my $folder = shift;
return (-f $folder && $folder =~ /.gz$/);
}
1;
These can even be defined inline ...
#!perl -w
use strict;
use Email::Folder;
use Email::LocalDelivery;
# copy all mail from an IMAP folder
my $folder = Email::Folder->new('imap://example.com'); # read INBOX
for ($folder->messages) {
Email::LocalDelivery->deliver($_->as_string, 'local_mbox');
}
package Email::FolderType::IMAP;
sub match {
my $folder = shift;
return $folder =~ m!^imap://!;
}
1;
If there is demand for a compatability shim for the old "register_type" method then we can implement one. Really though, this is much bet-
ter in the long run.
