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.

Not only can Unison sync between Windows and Unix ( OSX, Solaris, Linux etc.) systems, it also unrestricted in terms of which system can be the host.

Common uses include syncing configuration files, photos, and other content.


# pacman -S unison

This provides an cli, gtk(2) frontend


In order to use Unison you need to create an profile, you can use a GUI or you can manually create a profile in Template:Filename.

If you want to use the GUI, run:

$ unison-gtk2

Else, edit the default config file:

# nano ~/.unison/default.perf

First define the root of what you want to sync:


Then define the root where sync it too:


Optionaly, you can give arguments to ssh:

sshargs=-p 4000

Now you are going to define which directories and files to include in the sync

# dirs
# files

You can also define which files to ignore:

ignore=Name temp.*
ignore=Name .*~
ignore=Name *.tmp

For further references check the Unison documentation.


When your profile is setup you can start syncing:

$ unison <profilename>



And select the profile. Unison has a nice interface where you can view the progress and changes.
