I haven't tried this one:

https://github.com/andreafabrizi/Dropbox-Uploader

But I like the idea - command-line script. Nothing fancy. Should run on any system with Bash and curl on them.

You could look into:

* rsync
* duplicity
* syncthing

What is the way to synchronize files with a remote storage like
Dropbox? I work in several places and I need to get the same document
files in these places. On Debian I was using just Dropbox. I need a
free solution from Guixsd.
