The problem was noclobber was set in .cshrc. I obviously need to become a
little more familiar with my shells.
Thanks to the above and the future replyees.
When I try 'cat /dev/null > targetfile' I get:
targetfile: File exists.
I searched the archives but didn't find anything on this. I remember
seeing this before but forgot where I saw it. I've checked the permissions
on null (666 root:sys) under /devices as well as the link under /dev (777
root:other). The target file is 600 root:sys and is a text file. I am
logged in as root.
