I was afraid someone was going to say something to that effect, it never 
seems to be that easy.  BTW, I'm running into problems with 'grep -R 
<hostname> *' on Red hat 9.  It never seemed to complete (waited an hour 
on a 1.7GHz host with a 40GB HD which is 73% full).  I then decided to 
get a little omre sophisticated and do (at /)

for i in `ll | grep ^d | awk '$0 ~ "dev" {next}; $0 ~ "proc" {next}; 
{print $NF}'`; do grep -R <hostname> $i; done

but grep still ran out of resources in /var.  Any ideas or, by the time 
I get to /var, do I care?
