Eric Appreciate your prompt help.

I had thought that the relative addresses resolved to absolute addresses before execution. IOW, that the relative paths in the command line appear to rdiff as absolute paths or lists of absolute values when it is executing because the shell resolves them before passing them as arguments to the program. Not? Ah. It looks like there is a sinkhole in my understanding of shell behavior. The trivial tests now run as expected. Onward. Thank you very much for your help. (Bookkeeping) I am replying to the list in response to your email but not copying you. Is that the usual best way? Or should I copy you as well? (I have not been active in lists for a very long while.) I normally top-post and leave the minimum quote needed for clarity. From dial-up days. Not sure if that is best on a list now. Better to always quote fully, or maybe interleave relevant snippets and crop less germane bits? Or some other form? Regards, Rufus
