you are absolutely right - I fnid it strange that so many commandline apps
stick their 'normal' output to stderr (like I said to Edward: "how is
'Syntax OK' in any way to be considered an error?").
oh well at least now I no how to handle the issue - and I'll be sticking rhe
'2>&1' after ever command sent to the shell via exec() from now on :-)
thanks for your help.

I just read the same advice in the manual. :-)
but there no web-request involved here (and I want to keep the script as portable as poss.)
it's actually a custom CMS installer for a mini CMS thang I wrote ... (it needs
to restart the webserver after an install is complete)
