It's probably either one of two reasons, or a combination of the two.
One, your glob() function may not return any items.
Two, your system may have disabled the use of the exec(), passthru()
and/or system() functions due to security. In any case, running a command
for this in PHP is not needed, just use the built-in PHP functions instead.
Assuming you use PHP 5, and that your use of the glob() function is
correct:
$unix = ".unix";
foreach (glob($usedir."[12_]*") as $filename) {
// doing this in a single operation
file_put_contents($filename.$unix, str_replace("\r", "",
file_get_contents($filename)));
}
