Happy Friday Monks! I was wondering how I would pass a regex like this: 

(/opt/backups/maindb[0-9]+.db/table[0-9]+.tn/chunk[0-9]+.cn/)

as an argument to a subroutine which executes a command on the (one and only) path matching that regex? Sample below hopefully illustrates what I'm trying to do. 

#!/usr/bin/perl -w
use strict;

my $regexStr = qr{[0-9]+};
my $suff = ".dn";

listThisFolder($regexStr);

sub listThisFolder
{

    my ($regexStr) = @_;
        my $getDir = ("c:\\sh\\");
    
    # I know that the folder exists, but I don't know what the table
        # suffix or chunk suffix would be (table-129.tn or table-001.t
+n, etc).
    # $ls would hold the contents of the folder which expanded from th
+e regex
    
    my $ls = `dir $getDir$regexStr$suff`;
        print "$ls\n";
    #return($ls);
}
