Hello Bill: Thanks again for your help. Does the line wrap look better now? I reduced from 76 to 66. Regarding inodes - /usr is 778MB and began with 99,838 inodes. That would jive approximately with your million for 10G drive. It now has 96M of free space but only 590 inodes remaining. This heavy drain on inodes occurred when I downloaded the full Ports tree a month or so ago. Not sure of the numbers but it was clearly a TON of small files :--). /usr is /dev/ad0s2g - I cannot remember from my install but think that Windows may be the first partition..??

I suspect that since the Ports download is an infrequent deal and most of my other files are much larger than the 500B or so of the Ports that the problem will be alleviated by adding space with a proportional number of nodes - (provided the next Ports update does not leave me with tons of debris) I will do some hunting for info on single user mode and growfs before proceeding. Is it necessary for me to user single user mode if I am the only user? I can of course restrict myself to a single logon. Thanks again for such really good help.
