no, it was several other tasks that I had t o do very carefully by hand. I was going to write an awk script. I figured there were others ways. my desktop is a flavor of linux that i don't know. it seems to be lacking in many common unix binaries; md5 is one that I spent an hour checking. zero. your first way works very well and will serve. many thanks. now I can listen to: /Lectures on the Critique of Pure Reason which is now safely in my home directory in several mp3 files. > > It's a real shame Unix doesn't have a really good tool for comparing > two directory trees.

REmember CP/M and MP/M? I started out with a dual 8085/80888 box with MP/Mand wrote notes and letters that were stored on 8" twin floppies. circa mid-1980's I transferred a boatload of floppies onto my 386 with SVR2 with uucp and others C programs on the 8088 box. it took forever and things keep faulting, but I got it done. eventually. > -- > Kevin P.
