Hi Monks, I need some wisdom with how to quickly and easily set up a for loop. Here's what I want to do. I have multiple directories, and within each of these directories, there is either a file with a certain extension, say *.txt, or there is not. What I need to do is loop through each of these directories to check if the file that has a *.txt extension exists, and if that file does exist, I need to copy another file within that directory -- let's call that file $out. Here's my code setup: 
#!/usr/bin/perl
use warnings;
$out = "outFile";
$newdir = $newdirectory;
open(TABLEA, "dirlist");
@tablea = <TABLEA>;
foreach $dir (@tablea) {
    chdir $dir;
    if (glob("*.txt")) {
        system("mv $out $newdir");
    }
}

So, the directory list is set as an array, @tablea, and each directory is called $dir. If the file w/ extension *.txt exists, mv the $out file (within that directory) to the new directory, $newdir. Repeat the check for each directory. If run this script, nothing gets sent to new directory, so I was wondering how I could improve this script so that this script runs correctly? Thanks.
