My last message was kind of bogus, I apologize. The problem is that test -w always fails on directories. Seems that the open call in SunOS 4.0 returns and error if you try to open a directory for writing. Thus, open may not be the way to handle the -w switch to test. Perhaps the fix would be to use access instead? Pete
