install the module in global: npm install -g fsmonitor.
run command in shell: fsmonitor -d .
Then any change happens in the directory, the sync script will be executed, and the two directories will be in sync.
Unison is a file synchronization tool for Windows and various Unix-like systems (including macOS and Linux).[3] 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.[4][5][6][7] Syncing replicas directly Unison is independent of third-party providers.
Features of Unison include to handle file changes on both sides of replication; conflicts (same file changed on both sides) are displayed and can be resolved manually, optionally creating backups of changed files. Unison allows synchronization via computer networks (LAN, Internet) by direct connection (socket) or tunneled via ssh.[8] By using the rsync algorithm only changed blocks of files have to be transferred, thus saving bandwidth.
Unison can be called via the command line with parameters or controlled via profile files.[9][10] It can be executed interactively or batch-controlled automatically. In batch mode, unique changes are automatically synchronized. Files with replication conflicts are skipped.
After startup, Unison checks the file inventory per directory or computer and compares the timestamps of the files. If it detects changes, the changes to the corresponding files are analyzed in more detail. Afterwards Unison creates a replication list with suggestions for their synchronization and marks conflicts that cannot be resolved automatically.
GUI versions of Unison exist for interactive use. Under Windows and Linux they are generally based on GTK+. The GUI versions allow an easier overview of the replicas and the proposed synchronization. Changes can be marked individually by keyboard or mouse and then implemented in bundles.
Unison differs from Syncthing in several ways, the main one being that Syncthing is designed for always-on, automated synchronization, whereas Unison is designed for synchronization that is triggered and monitored by the user. Syncthing is peer-to-peer, while Unison is not.
In all this time Unison never ruined my data in the sense of shredding file contents. It displayed, however, some sensitivity to edge conditions such as files in use, permissions, or cross-platform issues. You will need to be careful to research this if you encounter any errors when synchronizing your files with Unison. Save your logs.
I used it for quite a while (to synch between desktop and laptop). As the others write, it is quite careful during synch, and I never lost any files. In case of problems it may require a (time-consuming) resynch, but everything sorts itself out in the end.
I've used Unison on my Macs for at least 8 years. I've never had Unison corrupt or lose a file. Early on, I had some issues with Unison not understanding resource forks, which led to failures to synchronize.
Another failing is Unison does NOT keep the modified times by default (it is however possible to use the -times option to make unison synchronize file modification times)! If you synchronize, the modified times are set to the file creation time on the destination:
Unison is a bidirectional file synchronization tool that runs on Unix-like operating systems (including Linux, macOS, and Solaris) 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.
If one runs unison within a terminal emulator capable of maintaining a suitable scrollback buffer, there is no purpose in having to confirm every non-conflicting change; set the auto option to true to avoid these prompts.
The unison default diff command is diff -u CURRENT2 CURRENT1. When looking at the output of this command, it can be difficult to remember which changes will be kept when propagating from left to right ('>'), versus right to left ('' keeps lines which start with '>':
Using the variable CURRENTARCH tells Unison that you expect to do 3-way merges with a common ancestor, which is only possible if the "backupcurrent" preference has been set previously to the last sync. To perform an ordinary 2-way merge in a terminal, one could use the following configuration instead. This also uses emerge.el, which some find preferable to ediff.el:
When syncing configuration files which would vary (e.g., due to endemic applications, security-sensitive configuration) among systems (servers, workstations, laptops, smartphones, etc.) but nevertheless contain common constructs (e.g., key bindings, basic shell aliases), it would be apt to separate such content into separate configuration files (e.g., .bashrc_common), and sync only these.
Default unison data directory is /.unison. This directory will contain profiles, but also logs and raw data. If you want to change it, you can set an environment variable (in your shell config or before using unison command):
unison is basically like rsync except it goes both ways. It copies in both directions at once and tries to merge the changes from both sides. Imagine you had an extra copy of your music library on a computer at work. You add one song at home, and a different song while at work. You could use unison to copy the new songs from each computer, thus synchronizing both copies of the music library.
You could say that Syncthing is like unison except it can sync between more than 2 computers at once. And unlike rsync and unison, it can run continuously, syncing changes as they happen. Some people use it to replace Dropbox or Bittorrent Sync, but it has a lot of uses.
I am a long-term unison user. A friend asked me to evaluate syncthing. I have significant experience evaluating commercial two-way sync software, and unsuccessfully corresponding with their developers over undesired program behavior.
unison is written by Benjamin Pierce (a world-class computer scientist) with well-informed community support. There are two issues that unison gets right, and all commercial products get wrong: symlinks, and atomic directories.
If one makes minor changes to the same mounted disk image on two machines, and then does a two-way sync, one could buy the farm. Most likely, there will be a conflicting root file alerting one to the problem. Far cleaner to simply be forced to choose one disk image directory over the other. Functionally, the entire disk images are in conflict, not specific files within.
I used one big ignore regex to do this because all other approaches didn't work. If unison would support negative lookaheads, this would have been so much simple, but I had to use an emulation through negative character classes as described here:
Hidden in the back pockets of a few savvy system administrators is a free, mature, and open source file synchronization tool called Unison. Like sound coming together from two speakers, Unison does a solid job synchronizing smaller files and directories between (at most) 2 systems.
Unison also works in client-server, hub-and-spoke topology for backup & sync. Each spoke pairs with the hub; thus, changes are only propagated between the hub and the one spoke. This is by no means real-time nor scalable, but may suffice for basic file backup use cases.
Unison runs on a variety of Unix-like operating systems (Linux, macOS/macOS X, Solaris, FreeBSD, et al) and Microsoft Windows. You can install a graphical user interface or drive Unison from the command line. Unison is cross platform and you can backup & sync files between different operating systems (e.g. from Unix to Windows) but according to the Unison Readme each system must include an OCaml compiler. The Unison FAQ recommends keeping the same software versions on all replicas.
Without the ability to capture file changes in real-time, Unison (as well as rsync and other point-to-point tools) are not practical solutions for systems containing larger numbers of files. That said, the Unison file synchronizer may be useful in scenarios such as:
No real-time file change detection: Unison, Rsync, and other conventional folder comparison and file synchronization tools are not real-time. Unison could theoretically be configured to track iNotify file system notifications in Linux but Unison is not real-time nor file-change-aware out of the box. By contrast, Resilio Connect offers highly efficient, real-time file change replication for a variety of operating systems (Windows, Linux, et al) to detect and replicate changes on-the-fly in real-time.
I use unison on a number of machines, all running ubuntu 20.04. For some baffling reason, one morning two of these machines starting opening a GUI whenever I did a file transfer. The other machine only generates text. The default.prf files on all machines are identical so that's not the source of the difference. I'd like to disable the GUI on the two machines that are running it. Couldn't find anything in the manual about how to do this. Could somebody advise please?
Please check the chain of links until you reach the executable file(s) and let us hope there is still a text UI version in 20.04 (It is in 18.04 which I'm running: /usr/bin/unison-2.48.4 and /usr/bin/unison-2.48.4-gtk)
I'm trying to use unison (the GUI) to synchronize two folders; unfortunately, one of them is a Windows drive mountpoint with properties set to 0777 - and unison shows that as a difference which requires synchronization.
Is there a way two sync multiple computers (i.e. particular directories in the home folder) automatically using Unison? If not, is there an alternative that can do this? I'm not completely against opening Unison all the time and doing the sync manually, but when it opens you must select a profile, which corresponds to just one directory, so you have to sync each individually. Add to that, the IP address is dynamic, and therefore has to be edited. This is quite tedious, and it seems there should be a simpler way. Am I missing something? Is there a way to simplify this process (possibly a bash script)?
