I am running a system command to a file passing the data to a filehandle, but the if clause does not work. My goal is to run a system app command and if it creates a file greater than 0 bytes then use MIME:Lite to email the data otherwise just "touch" a file.Any ideas? thank you!

## Set pragmas

        use strict;

        my $foreigntapes="/usr/local/log/foreign_tapes.log";
        delete $ENV{'IFS'};
        local $ENV{'PATH'}= "/usr/epoch/bin:/usr/epoch/EB/bin:/usr/bin
+:/usr/sbin:/bin:/sbin";

        open (OUT, ">$foreigntapes") || die "could not open file:$!";
        my @ftapes = grep s/^barcode=//, `evmvol -w label_state=1`;
        my $svsel = select; select OUT; $| = 1;
        print OUT "@ftapes";
        if ( -s OUT ) {
                     print "file is greater than 0 bytes \n";
        }
