Hi all, I would like to synchronize a part of the source file with a part of the destination file. In detail I would like to - synchronize a file on a remote host from line "n" onwards with the file content on the local host starting with line "n" in the file. - the firs "n" lines of the files on the local and remote host should not be changed. My questions are: 1) Is it possible to do this with rsync? 2) Has anyone done that before? 3) How can I do this/where can I get more information?

I think you'd best use a script to first split the two files, symc the
truncated parts with rsync and merge them again afterwards.

Hi all,
I would like to synchronize a part of the source file with a part of the
destination file. In detail I would like to
- synchronize a file on a remote host from line "n" onwards with
the
file content on the local host starting with line "n" in the file.
- the firs "n" lines of the files on the local and remote host
should
not be changed.
My questions are:
1) Is it possible to do this with rsync?
2) Has anyone done that before?
3) How can I do this/where can I get more information?
Many thanks,
Rolf

I'd start by reexamining the problem. Rsync is for syncronizing directory trees and incendentally files. Only syncronizing part of a file is a very unusual requirement. In most cases when a very unusual requirement appears (like this one) it is because the available options haven't been explored. This sounds like a config file, most config file formats support something like an #include directive so you can seperate local from global. The same holds true for scripting languages. More than one person has suggested doing cut; rsync; cat If it does come to that it might be better to only cut once. Keep it as two seperate files and cat them together into a third after each rsync. But first explore the possibility of having whatever uses the file read from to files instead of the one; that would be less fragile. -- ________________________________________________________________ J.W.
