note 59791 added to ref.exec

In response to the comment by 'daniel dot hopp at godot dot de' regarding the use of start-stop-daemon to exec a process within a session: start-stop-daemon will probably not be a good choice. start-stop-daemon with the --start option will not start the daemon if any matching process is found. In other words, if you are using it to start a process running 'myscript', and there is another instance of 'myscript' found in the process table, start-stop-daemon will *not* start another process and will return 1, unless --oknodo is set. Check out a man page for start-stop-daemon. ---- Manual Page -- http://www.php.net/manual/en/ref.exec.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59791 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59791&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59791&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59791&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59791&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59791&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59791&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59791&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59791&report=yes Search -- http://master.php.net/manage/user-notes.php
