    Hi,

    For some reason on a certain MAC machine we use (Darwin Kernel Version 10.8.0, 32bit, STAF 3.4.6), saving a command that includes our php into a file and then attempting to execute the file, causes STAF to hang.

    that is: 

    /usr/local/zend/bin/php -v - works fine from the cmdline
STAF local PROCESS START SHELL COMMAND "/usr/local/zend/bin/php -v" WAIT 60m RETURNSTDOUT RETURNSTDERR - works fine

    BUT, saving this cmd into say /tmp/bad (+ chmod 777) , and then running:
    STAF local PROCESS START SHELL COMMAND "/tmp/bad" WAIT 60m RETURNSTDOUT RETURNSTDERR

    causes STAF to hang. This problem does not occur on a another MAC machine we use (Darwin Kernel Version 11.1.0, 64bit).

    Here's a dtruss of the cmd if it might be of help:

    Forgot to mention that other commands I place in such file for work, such as 'date -u' (or even executing 'php -v' using the php binary provided by apple).

    What do you mean by this causes STAF to hang?  Do you mean that the STAF PROCESS START request never completes? 

    Are you sure that the file you are running via the STAF PROCESS START command has been closed?

    Does adding option STDIN and specifying the name of a file that you create that contains nothing resolve the problem?  For example:

    touch /tmp/empty.txt

    STAF local PROCESS START SHELL COMMAND /tmp/bad RETURNSTDOUT RETURNSTDERR STDIN /tmp/emptry.txt WAIT

    By hang I meant that STAF does not return any output given a reasonable timeout.
    Indeed, adding the STDIN /tmp/empty.txt bit seems to workaround the problem - thx !
