Hello all Help please. I am new to rsync. I would like to automatically synchronize two directory trees. Say I have two machines that I use regularly. One is at the office and one is at home. (I would like to avoid having anything like an NFS mount.) If I am at the office and I work on a document, then I would like to see those changes reflected in the copy at home by the time I get to open it there. Likewise, if I am at home and I have worked on a document overnight, I would like to see those changes in the document on my office machine by the time I open it there next morning. I have tried something like this. rsync -avuzb --rsh=/usr/local/bin/ssh --exclude ´*~´ [EMAIL PROTECTED]:/home/rob/toppage . rsync -Cavuzb --rsh=/usr/local/bin/ssh . [EMAIL PROTECTED]:/home/rob/toppage All it seems to do is copy all the files across and then back again. I would imagine the answer is simple, but I can't figure it out. On another matter, how do I get ssh to log in automatically without prompting for a password. Many thanks Rob -- Dr. Robin M.
