Re: Re: Re: filtering file names to be added to an array...maybe.

As the docs say, it globs like /usr/sh would. And I tested this sort of glob on Win32 and it worked just fine.

Update: Excellent point, Coyote.

There is a small issue with glob between Win32 and nix. Consider a directory that contains files named "uc.DAT" and "lc.dat". Let's use this code to glob all files with an extension of dat on a linux box and a Win98 box (I don't have an NT box handy so YMMV). `#!/usr/bin/perl -w use strict; use Data::Dumper; my @files = glob('.dat'); print Dumper(\@files);` [download] Running this on linux yields this output: `$VAR1 = [ 'lc.dat' ];` [download] On Windows 98, you get the following: `$VAR1 = [ 'lc.dat', 'uc.DAT' ];` [download] The problem here is that Windows is case insensitive, but case preserving. This could be a potential problem if you are expecting the same output from glob on both platforms. ---- Coyote	[reply] [d/l] [select]

glob

#!/usr/bin/perl -w

use strict;
use Data::Dumper;

my @files = glob('*.dat');
print Dumper(\@files);
[download]

$VAR1 = [
          'lc.dat'
        ];
[download]

$VAR1 = [
          'lc.dat',
          'uc.DAT'
        ];
[download]
