I am looking at add some code to the rsync tool but want to
know if I am "totally out to lunch".
I realize that my example is so trivial that I am sure I will
get replies of "don't do it that way", but bear in mind
that it is just an example, and there are real world cases
where I think this functionality would be useful.
I am trying to figure out if rsync can do something like
cat myfile.dat | rsync - remoteHost:/some/path/myfile.dat
which would take a stream of data and send/store it onto the
I don't think that this is possible with the current command line
rsync utility. My questions is more about "can the rsync algorithm
Technically, the question boils down to "Is rsync a single pass
algorithm, or is it a multi-pass algorithm?"
If it is a single pass algorithm then all is good.
If it is a multi-pass algorithm then how big of a buffer does it
need to perform the passes? Namely, is it a block by block multi-pass,
or is it a complete file/object multi-pass algorithm.
Any help or pointers to this detail are appreciated.
