API:Client code/Bash

The following is an example of how to use w:Bash (Unix shell) to login and upload a file.

You will need the curl package which you can get with:

sudo apt-get install curl

Curl will need to write 2 files, one for the cookiejar, and one to store files if you need to upload.

Bash is not very efficient, but it is widely available.
