to find a user on the pegasus system by location try the folowing

'finger | grep -i [location]'
This works by taking the output of the finger command (which lists everyone logged onto the pegasus system) and then filtering it with the grep utilty (which is a text search utility like 'find' in dos). The '-i' makes it case insensitive.
