tree backup script - file type problem

by barathbr (Scribe)
on Sep 07, 2004 at 23:05 UTC ( #389231=perlquestion: print w/replies, xml ) Need Help??

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


I am just in the process of writing a little script to back up specific files from multiple servers on my network. The problem is that some of the files dont have standard extensions. (e.g) I could have a binary with no extension or a cap file named as .txt.

My question is, is there a module which gives output similar to the `file` command ?? I am on windows with A perl 5.8

pl. note I have hunted on cpan for modules, but just wanted to make sure I am using a standar module which people know works

Also, is there a simple way to access windows shares from within a script. I am currently just mapping a drive to the $ share within windows and hardcoding the path. That just increases my login time like crazy.

    use Win32::NetResource; $ShareInfo = { 'path' => "C:\\MyShareDir", 'netname' => "MyShare", 'remark' => "It is good to share", 'passwd' => "", 'current-users' =>0, 'permissions' => 0, 'maxusers' => -1, 'type' => 0, }; Win32::NetResource::NetShareAdd( $ShareInfo,$parm ) or die "unable to add share";

    Here's a simple file-type reporter based on File::Type, and of course our wierd friend, File::Find:

    use strict; use warnings; use File::Type; use File::Find; find( sub { -f && print "$_\t => ", File::Type->new()->checktype_filename($_), $/ for $File::Find::name; }, scalar(@ARGV) ? @ARGV : './' );

    It's a little concise; I was trying to have some fun with it. One hint: The 'for' clause is used to alias $_ to $File::Find::name so that I wouldn't have to keep typing it all over the place. Also, since I only use $obj->checktype_filename() once, I chose to not store the object's ref in a variable, but rather, just dereference the return value of File::Type->new(). ...a couple of golf tricks that didn't seem to hurt readability too much.


      Thanks david, I will just try it out with the snippet that you have written here. I think this in tandem with the netresource module should just do the job for me ...

    The sources for file are available here if you want to try to compile it in Windows.

      Oh no!!! I am not going down that road. I have already seen File::Type on CPAN, but am just concerned about stability issues. This script will be running every once in a while and it just has to be dependable. Thats my only concerns. If it comes to it, I would rather sacrifice time and bandwidth in just mirroring whole directories, since it is on the local network. I was just hoping to get some recomendations on any other modules that people might already be familiar with.

      Thanks anyway
