Thanks for your input on this issue...

Hi,
I would like you to check this:
cd /tmp
sudo -u nobody cp /home/Steve/Shared/workspace/xxx/xxx/bootrom.pxe.o .

Simon,
Thanks again. - I'm showing my Linux user ignorance!!
My user nobody cannot login or accept an su but
sudo -u nobody cp bootrom.pxe.o /tmp/
Works OK and leaves the expected entry

unless you have user=root somewhere.
Try "su
