DESCRIPTION

This manual page briefly documents Unison, and was written for the Debian GNU/Linux
distribution because the original program does not have a manual page. For a full
description, please refer to the inbuilt documentation or the manuals in
/usr/share/doc/unison/. The unison-2.48.3-gtk binary has similar command-line options, but
allows the user to select and create profiles and configure options from within the
program.

Unison is a file-synchronization tool for Unix and Windows. It allows two replicas of a
collection of files and directories to be stored on different hosts (or different disks on
the same host), modified separately, and then brought up to date by propagating the
changes in each replica to the other.

Unison offers several advantages over various synchronization methods such as CVS, Coda,
rsync, Intellisync, etc. Unison can run on and synchronize between Windows and many UNIX
platforms. Unison requires no root privileges, system access or kernel changes to
function. Unison can synchronize changes to files and directories in both directions, on
the same machine, or across a network using ssh or a direct socket connection.

Transfers are optimised using a version of the rsync protocol, making it ideal for slower
links. Unison has a clear and precise specification, and is resilient to failure due to
its careful handling of the replicas and its private structures.

The two roots can be specified using an URI or a path. The URI must follow the convention:
protocol://[user@][host][:port][/path]. The protocol part can be file, socket, ssh or rsh.
