I just took a quick look, and while it seems that I might be able to
use Unison in place of rsync in my script, it doesn't appear that it
detects changes as they occur and automatically propogates the changes
to the remote machine.
My script is invoked as follows:
constant_sync /some/local/path remote_machine:/some/remote/path
It first rsyncs ``/some/local/path'' with ``/some/remote/path'' on
``remote_machine''. It then uses fam to monitor changes to files in
the ``/some/local/path'' directory hierarchy and rsyncs local files as
they change to the remote machine.
Of course, if I am mistaken about Unison's (or rsync's daemon mode)
capabilities, I'd like to know. I don't mind giving up my script if
there's some other already existing tool that does this job well.
Thanks for telling me about Unison though. I wasn't aware of it until
now. For those that want to get to it quickly without (an almost
equally quick) Google search, the location is:
