Scripts aren't very good at extracting information that is not present in the inputs that are provided. If you were to look at the output produced by rsync instead of looking at the messages your script is producing before it runs rsync and after rsync completes, you might be able to accurately count the number of successful and the number of failed attempts to transfer a file. But when that information is not available, there is no way to make it magically appear out of the ether.

NAME
librsync - library for delta compression of streams SYNOPSYS
#include <stdio.h> #include <stdlib.h> #include <librsync.h> cc ... -lrsync DESCRIPTION
The librsync library implements network delta-compression of streams and files. The algorithm is similar to that used in the rsync(1) and xdelta(2) programs, but specialized for transfer of arbitrary-length octet streams. Unlike most diff programs, librsync does not require access to both of the files on the same machine, but rather only a short ``signature'' of the old file and the complete contents of the new file. The canonical use of librsync is in the rproxy(8) reference implementation of the rsync proposed extension to HTTP. It may be useful to other programs which wish to do delta-compression in HTTP, or within their own protocol. There are HTTP-specific utility functions within librsync, but they need not be used. A number of tools such as rdiff(1) provide command-line and scriptable access to rsync functions. SEE ALSO
rdiff(1) rdiff and librsync Manual http://rproxy.sourceforge.net/. draft-pool-rsync BUGS
The rsync protocol is still evolving. There may be bugs in the implementation. The interface may change in the future, but it is becoming more stable. Many routines will panic in case of error rather than returning an error code to the caller. Patches to fix this are welcome, but at the current state of development aborting seems as useful as trusting to possibly-incomplete checking in the client. AUTHOR
