1) not without lots of surrounding logic.
2) it hasn't been reported on the 6 o'clock news.
3) too many ways and places to list.
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.
