Example 40.1 The file ~/.unison/example.prefs
root=/home/tux/dir1
root=ssh://wilber@server//homes/wilber/dir2
batch=true
For each pair, a synchronization log is maintained in the user directory ~/.unison.
Configuration sets, such as ~/.unison/example.prefs, can also be stored in
this directory. To start the synchronization, specify this file as the command-line param-
eter as in unison example.prefs.
40.3.3 For More Information
The official documentation of Unison is extremely useful. For this reason, this section
merely provides a brief introduction. The complete manual is available at
http://
and in the SUSE package unison.

40.4 Introduction to CVS
CVS is suitable for synchronization purposes if individual files are edited frequently
and are stored in a file format, such as ASCII text or program source text. The use of
CVS for synchronizing data in other formats, such as JPEG files, is possible, but leads
to large amounts of data, because all variants of a file are stored permanently on the
CVS server. In such cases, most of the capabilities of CVS cannot be used. The use of
CVS for synchronizing files is only possible if all workstations can access the same
server.
40.4.1 Configuring a CVS Server
The server is the host on which all valid files are located, including the latest versions
of all files. Any stationary workstation can be used as a server. If possible, the data of
the CVS repository should be included in regular backups.
When configuring a CVS server, it might be a good idea to grant users access to the
server via SSH. If the user is known to the server as tux and the CVS software is in-
stalled on the server as well as on the client, the following environment variables must
be set on the client side:
