please excuse my inability to understand this code.
but what is: while ( <*> )
and where is the piece of code that tells what directory/path to look in?
where does it go?
Thanks,
Lino

Well without still more info such as what you want to do with the list this script
will read the current directory and store all the file names into an array. You could
use a hash or even process each file one at a time. Code is untested.

Code
-=-=-=
use strict;
use warnings;
my @files;
while ( <*> ) {
next if ( /\.|\../ ); # skip the '.' and '..' directory
my $filename = $_;
push ( @files, $filename );
#### or you could process each file as it is found ...
open ( IN, "<$filename" ) or die (" could not open file $!\n" );
while ( ){
###Parse file here
}
}
foreach my $ file ( @files ) {
open ( IN, "<$file" ) or die (" could not open file $!\n" );
while ( ){
###Parse file here
}
}
