This only gets directory information.
Basically - the data you are talking about is only available in kernel mode. What you want to do is look into the filesystem code for your box - ufs, ffs, ext2, or whatever.
Google for 'McKusick fast file system' to see what I'm talking about - there are some videos.
I have a data file with over 500,000 records/lines that has the header throughout the file.

Hi ,
I have a typical situation. I have 4 files and with different headers (number of headers is varible ).
I need to make such a merged file which will have headers combined from all files (comman coluns should appear once only).
For example -

Hey Guys,
Absolute neewbie here. I am trying to see if it is possible to edit headers/meta-data of files in Mac OSX. I am basically trying to change an audio file header to read 16bit instead of 24bit.

lwp::protocol::psgi
LWP::Protocol::PSGI(3pm) User Contributed Perl Documentation LWP::Protocol::PSGI(3pm)NAME
LWP::Protocol::PSGI - Override LWP's HTTP/HTTPS backend with your own PSGI applciation
SYNOPSIS
use LWP::UserAgent;
use LWP::Protocol::PSGI;
# can be Mojolicious, Catalyst ... any PSGI application
my $psgi_app = do {
use Dancer;
setting apphandler => 'PSGI';
get '/search' => sub {
return 'googling ' . params->{q};
};
dance;
};
LWP::Protocol::PSGI->register($psgi_app);
# can hijack any code or module that uses LWP::UserAgent underneath, with no changes
my $ua = LWP::UserAgent->new;
my $res = $ua->get("http://www.google.com/search?q=bar");
print $res->content; # "googling bar"
DESCRIPTION
LWP::Protocol::PSGI is a module to hijack any code that uses LWP::UserAgent underneath such that any HTTP or HTTPS requests can be routed
to your own PSGI application.
Because it works with any code that uses LWP, you can override various WWW::*, Net::* or WebService::* modules such as WWW::Mechanize,
without modifying the calling code or its internals.
use WWW::Mechanize;
use LWP::Protocol::PSGI;
LWP::Protocol::PSGI->register($my_psgi_app);
my $mech = WWW::Mechanize->new;
$mech->get("http://amazon.com/"); # $my_psgi_app runs
METHODS
register
LWP::Protocol::PSGI->register($app);
my $guard = LWP::Protocol::PSGI->register($app);
Registers an override hook to hijack HTTP requests. If called in a non-void context, returns a Guard object that automatically resets
the override when it goes out of context.
{
my $guard = LWP::Protocol::PSGI->register($app);
# hijack the code using LWP with $app
}
# now LWP uses the original HTTP implementations
unregister
LWP::Protocol::PSGI->unregister;
Resets all the overrides for LWP. If you use the guard interface described above, it will be automatically called for you.
