Hi there,

What is a good syncronisation tool on linux?
Is there a command that would allow me to compare two folder content?
I need it for my backup.


Thank you

Ahh, the answer you seek are Python scripts, my friend!!!

What about the directory contents do you need to compare? file contents, size, creation dates? No doubt there are ways to do it. If you give an accurate description of what it is you want to do, I'm sure I or someone else can help you do it or point you in the right direction. For the time being with the criteria you gave, I can point you to take up your cross and go search for the Holy Grail by learning Python.

And there's also diff (it's not just for files) and rsync (it's not just for remote sync) and so on.

Not that I wouldn't mind seeing some cool python.

I reply to Digiot, I need to compare dates and whether two folders have the same contents. I save all my work on my PC HD and I backup everything on a removable drive which contain the same folders and I need the backup drive to be up to date with the main HD after each backup.
Unfortunately I don't have any knowledge about Python. I only got basic knowledge in C, C++ and shell scripting.

In regard to Harlin, I actually just find out that diff could also work with folfers. I not sure if diff could do the job. If diff can work on modified date of file I am thinking of writing a shell script that might do the job.

Appreciate the help.

Sounds like rsync is more like what you're looking for then. It compares two directories and synchronizes them. It can even work over SSH across the network. You can read the man page for more info.

Dammit! I've been stuck at http://www.hillside.co.uk/articles/sunexpert.html for *hours* thanks to you.

I second that. Everybody should learn python, it's too easy not to learn.
