$cmd = "mv " . SITES_IMP . "site_* " . DB_UPDATES;
exec($cmd);

$arr = array();
$cmd = "ls " . DB_UPDATES . " site_* | wc -l";
exec($cmd,$arr);

i am of the impression that code proceeding an exec cmd will not execute until the exec is finished

in the above instance, the "ls" exec is executing before the "mv" exec has finished - when i know that 10 files have been moved, the "ls" exec returns 0 for a "wc -l", when running the code again it returns the number of files correctly - have placed sleeps between the commands and all works well

wondered if this is a bug in the exec cmd or my misunderstanding of its use
