Unison is a powerful tool that helps in synchronizing files and directories between multiple machines. If you want to use Unison on your latest nixOS installation, you can follow the steps given below.
Firstly, open the terminal window by pressing Ctrl+Alt+T or by clicking on the Terminal icon.
Before starting the installation process, it's recommended to update your nixOS to the latest version with the command:
sudo nix-channel --update && sudo nixos-rebuild switch
You can install Unison by running the following command in the terminal:
sudo nix-env -iA nixos.unison
This command installs Unison from the nixOS channel and makes it available system-wide. If prompted for a password, enter it and then wait for the installation process to complete.
To verify that the Unison installation was successful, run the command unison -version. The command should display the version of Unison installed on your machine. If it doesn't, something went wrong and you may want to try re-installing it.
With Unison installed, you're now ready to use it to synchronize files and directories between different machines. You can do this from the command line with the unison command, specifying source and destination folders, and any other options that you want to use.
To see detailed instructions on how to use Unison, run the command man unison.
That's it! By following these steps, you should now have a working installation of Unison on your latest nixOS system. With Unison, you can easily synchronize your files and directories between different machines, making it a great tool for managing your data across multiple devices.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
