Cloud storage is everywhere in today’s multi-device environment where people want to access content across multiple devices wherever they go. Dropbox is the most widely used cloud storage service due to its elegant UI and flawless multi-platform compatibility. There are numerous official or unofficial Dropbox clients available on multiple platforms.
Linux has its own share of Dropbox clients; CLI clients as well as GUI-based clients. Dropbox Uploader is an easy-to-use Dropbox CLI client written in BASH scripting language. In this tutorial, I describe how to access Dropbox from the command line in Linux by using Dropbox Uploader.

Install and Configure Dropbox Uploader on Linux

To use Dropbox Uploader, download the script and make it executable.

$ wget https://raw.github.com/andreafabrizi/Dropbox-Uploader/master/dropbox_uploader.sh
$ chmod +x dropbox_uploader.sh

Make sure that you have installed curl on your system, since Dropbox Uploader runs Dropbox APIs via curl.
To configure Dropbox Uploader, simply run dropbox_uploader.sh. When you run the script for the first time, it will ask you to grant the script access to your Dropbox account.

$ ./dropbox_uploader.sh

As instructed above, go to https://www2.dropbox.com/developers/apps on your web browser, and create a new Dropbox app. Fill in the information of the new app as shown below, and enter the app name as generated by Dropbox Uploader.

After you have created a new app, you will see app key/secret on the next page. Make a note of them.

Enter the app key and secret in the terminal window where dropbox_uploader.sh is running. dropbox_uploader.sh will then generate an oAUTH URL (e.g., http://www2.dropbox.com/1/oauth/authorize?oauth_token=XXXXXXX).

Go to the oAUTH URL generated above on your web browser, and allow access to your Dropbox account.

This completes Dropbox Uploader configuration. To check whether Dropbox Uploader is successfully authenticated, run the following command.

$ ./dropbox_uploader.sh info
