Free synchronise software for linux

Directory Synchronize is the small handy utility you always missed! Directory Synchronize is small, reliable, and fast. And best of all - it is Open Source; released under the GPL you are free to use and distribute it.
Directory Synchronize synchronizes the contents of one directory to another. That means you can use it to backup your data on a regular basis to another computer or another harddrive.
Or you can use Directory Synchronize to synchronize the data on your laptop with the data on your desktop.
Programmed in real platform independent Java you can use Directory Synchronize on nearly every computer platform including Windows, Linux and Macintosh.
Use the Directory Synchronize GUI for starting, pausing and stopping a synchronization.
Or use the GUI to easily create and store a configuration and use the command line to automatically start it every time you boot up your computer.
Enhancements:
- Some bugs have been solved.
- If a file can not be accessed, only a warning is issued instead of issuing a critical error and halting synchronization.
- If you select a directory instead of a file as a log for a directory definition, a line-separator was added instead of a file-separator.
- Some NullPointerExceptions in console mode have been fixed.
- The " " wildcard can be used for the path of the global log, and the " " wildcard can be used for the name of the current directory definition in the directory definition log filename.

Foxmarks Bookmark Synchronizer is a Firefox extension that synchronizes your bookmarks with other computers.

If you use Firefox on more than one computer, youll want Foxmarks. Install Foxmarks on each computer, and it will work silently in the background to keep your bookmarks synchronized. As a bonus, log in to my.foxmarks.com from any computer anywhere to access your bookmarks.

A simple wizard guides you through the startup process. After that, just forget about it. Its simple and solid.

syncpasswd is an Expect script that synchronizes passwords via SSH on multiple platforms (Linux/BSD, OS X, and Solaris).

It takes hostnames as a list of arguments and changes the specified user passwords on those hosts. syncpasswd outputs results to stdout and logs to /var/log/syncpasswd.log (by default).

syrep is a generic file repository synchronization tool. syrep software may be used to synchronize large file hierarchies bidirectionally by exchanging patch files. Syrep is truely peer-to-peer, no central servers are involved. Synchronizations between more than two repositories are supported. The patch files may be transferred via offline media, e.g. removable hard disks or compact discs.

Files are tracked by their message digests, currently MD5. The following file operations are tracked in the snapshot files: creation, deletion, modification, creation of new hard or symbolic links, renaming.

(The latter is nothing more than a new hard link and removal of the old file). syrep doesnt distuinguish between soft and hard links. In fact even copies of files are treated as the same. Currently, syrep doesnt synchronize file attributes like access modes or modification times.

syrep was written to facilitate the synchronization of two large digital music repositories without direct network connection. Patch files of several gigabytes are common in this situation.

syrep is able to cope with 64 bit file sizes. (LFS)

syrep is optimized for speed. It may make use of a message digest cache to accelerate the calculation of digests of a whole directory hierarchy.

Sonic Visualiser is an application for viewing and analysing the contents of music audio files.
The aim of Sonic Visualiser is to be the program you reach for when you find a musical recording you want to study rather than simply hear.
As well as a number of features designed to make exploring audio data as revealing and fun as possible, Sonic Visualiser also has powerful annotation capabilities to help you to describe what you find, and the ability to run automated annotation and analysis plugins in the new Vamp analysis plugin format.
We hope Sonic Visualiser will be of particular interest to musicologists, archivists, signal-processing researchers and anyone else looking for a friendly way to take a look at what lies inside the audio file.
Main features:
- Load audio files in WAV, Ogg and MP3 formats, and view their waveforms.
- Look at audio visualisations such as spectrogram views, with interactive adjustment of display parameters.
- Annotate audio data by adding labelled time points and defining segments, point values and curves.
- Overlay annotations on top of one another with aligned scales, and overlay annotations on top of waveform or spectrogram views.
- View the same data at multiple time resolutions simultaneously (for close-up and overview).
- Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on.
- Import annotation layers from various text file formats.
- Import note data from MIDI files, view it alongside other frequency scales, and play it with the original audio.
- Play back the audio plus synthesised annotations, taking care to synchronise playback with display.
- Select areas of interest, optionally snapping to nearby feature locations, and audition individual and comparative selections in seamless loops.
- Time-stretch playback, slowing it down to as little as 10% of the original speed while retaining a synchronised display.
- Export audio regions and annotation layers to external files.
The design goals for Sonic Visualiser are:
- To provide the best available core waveform and spectrogram audio visualisations for use with substantial files of music audio data.
- To facilitate ready comparisons between different kinds of data, for example by making it easy to overlay one set of data on another, or display the same data in more than one way at the same time.
- To be straightforward. The user interface should be simpler to learn and to explain than the internal data structures. In this respect, Sonic Visualiser aims to resemble a consumer audio application.
- To be responsive, slick, and enjoyable. Even if you have to wait for your results to be calculated, you should be able to do something else with the audio data while you wait. Sonic Visualiser is pervasively multithreaded, loves multiprocessor and multicore systems, and can make good use of fast processors with plenty of memory.
- To handle large data sets. The work Sonic Visualiser does is intrinsically processor-hungry and (often) memory-hungry, but the aim is to allow you to work with long audio files on machines with modest CPU and memory where reasonable. (Disk space is another matter. Sonic Visualiser eats that.)

ftpsync provides a tool for synchronizing directories over FTP.

ftpsync is a tool that allows updates to be incrementally and recursively made to remote FTP servers. It examines time stamps and sizes, and is designed to operate in a manner similar to rsync.

ftpsync implements the missing recursive PUT FTP command.

ClearCase::SyncTree is a Perl module that can synchronize a tree of files with a tree of elements.

SYNOPSIS

# Create a synctree object.
my $sync = ClearCase::SyncTree->new;
# Tell it where the files are coming from ...
$sync->srcbase($sbase);
# Tell it where theyre going to ...
$sync->dstbase($dbase);
# Supply the list of files to work on (relative or absolute paths).
$sync->srclist(keys %files);
# Compare src and dest lists and figure out what to do.
$sync->analyze;
# Create new elements in the target area.
$sync->add;
# Update existing files which differ between src and dest.
$sync->modify;
# Remove any files from dest that arent in src.
$sync->subtract;
# Check in the changes.
$sync->checkin;

See the enclosed synctree script for full example usage.

This module provides an infrastructure for programs which want to synchronize a set of files, typically a subtree, with a similar destination subtree in VOB space. The enclosed synctree script is an example of such a program.

The source area may be in a VOB or may be a regular filesystem; the destination area must be in a VOB. Methods are supplied for adding, subtracting, and modifying destination files so as to make that area look identical to the source.

Symbolic links are supported, even on Windows (of course in this case the source filesystem must support them, which is only likely in the event of an MVFS->MVFS transfer). Note that the text of the link is transported verbatim from source area to dest area; thus relative symlinks may no longer resolve in the destination.
