I was wondering if there might be some subtle problems which would bite me later.The main reason for most unix admins to use 'su -' is that it sets the environment... Some people put nasty things like "." into their path or do other things that might break stuff - LD_LIBRARY_PATH, ... there is tons of things that you usually don't want in the environment of the root user. Hence you use the dash and get rid of all of that... A long long time ago I actually remember discussions of switching the behavior of su to default to "su -" and having an additional switch for it to _not_ give you a login shell - all that simply because su without the dash can be such a nightmare...Peter.
I haven't found it to be a problem. I was just concerned that it
might be later. I have never put "." into my path.
