File::MMagic doesn't recognize rar file


V

Vilmos Soti

Hello,

File::MMagic doesn't seem to recognize rar files. (tar is ok).
The machine is running Debian Etch. Here is the perl version:

$ perl -v

This is perl, v5.8.8 built for i486-linux-gnu-thread-multi

Copyright 1987-2006, Larry Wall
....

Here is the version of File::MMagic:

$ head -3 /usr/share/perl5/File/MMagic.pm
# File::MMagic
#
# $Id: MMagic.pm 198 2006-01-30 05:24:17Z knok $
$

Here is my script:

############################## Script starts ##############################
#!/usr/bin/perl -w
use strict;
use File::MMagic;

my $magic = new File::MMagic;
my $type;

foreach my $file (<c.*>) {
$type = $magic->checktype_filename ("$file");
print "$file, $type\n";
system ("file $file");
print "\n";
}
############################## Script ends ##############################

And here is the output of the script:

$ ./a
c.rar, application/octet-stream
c.rar: RAR archive data, v1d, os: Win32

c.tar, application/x-gtar
c.tar: POSIX tar archive

$

Here are the last two lines from /usr/share/perl5/File/MMagic.pm:

# RAR archiver (Greg Roelofs, (e-mail address removed))
0 string Rar! application/x-rar

And here are the first few characters from c.rar:

$ xxd c.rar | head -1
0000000: 5261 7221 1a07 00cf 9073 0000 0d00 0000 Rar!.....s......
$

Do I do anything wrong or is it something else?

Thanks for your time, Vilmos

File::MMagic doesn't seem to recognize rar files. (tar is ok).

rar is the last entry in the file and there is no newline after that entry
which causes that line of data to be missed.

Edit your copy of MMagic: Go to the end of the line, press enter, and
save. That should result in rar files correctly being identified as
application/x-rar.

Please report this to the module author.

My copy does have a newline, but it doesn't have an empty line.
Maybe this was the problem. Now it works.
Edit your copy of MMagic: Go to the end of the line, press enter, and

application/x-rar.

Done, and it works now.

I did.

Sinan, thank you for your help.
