Basic usage

  • Synchronize two directories
unison <dir-a> <dir-b>
  • Selecting files to synchronize
    • Synchronize home directory, using Ignore facility to skip some files.
    • Create a subdirectory called shared, and synchronize that directory only.
    • (Linux only) Create a subdirectory called shared, with symbolic links to other local directories, and synchronize that directory only using follow (making symlink transparent).
    • Synchronize home directory as root, using -path switch on the command line:
      unison /home/username ssh://remotehost//home/username -path shared
      

      The -path option can be used as many times as needed, to synchronize several files or subdirectories:

      unison /home/username ssh://remotehost//home/username \
          -path shared \
          -path pub \
          -path .netscape/bookmarks.html
      

      These -path arguments can also be put in your preference file.

Configuration tips

  • On Samba / CIFS file system, ignore permissions:
perms = 0

Basic Profile

Here we assume that all profiles will include the default one. If not, a more complex solution is to create a file .unison/common-prefs, that would be included by all profiles, including the default one.
