That's all. ;)
On HP-UX if you give several option arguments to dirname then the HP-UX dirname would handle the first argument and then return an error due to the extra arguments. See this example: $ /usr/bin/dirname /one/two/three /four/five /six/seven /one/two $ echo $? 1 $ /usr/bin/dirname /one/two/three /one/two $ echo $? 0 It is an error on HP-UX dirname to supply extra arguments too. But your scripts must be ignoring the error. GNU dirname is simply reporting the error more loudly. :-) What is your script expecting to happen with the extra arguments? Surely that would also be a bug in your script since those extra arguments are not getting processed. Bob
