note 62234 added to function.shell-exec

I have perl script that helps in connecting from a Unix server to a cluster. This program runs perfectly well from the command line, but when I try to intrigrate it with my php code it doesn't work. Any help regarding this will be greatly appreciated. ---- Server IP: 64.71.164.2 Probable Submitter: 129.1.35.41 ---- Manual Page -- http://www.php.net/manual/en/function.shell-exec.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+62234 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+62234&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+62234&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+62234&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+62234&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+62234&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+62234&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+62234&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+62234&report=yes Search -- http://master.php.net/manage/user-notes.php
