Firstly, get the dropbox share link. It will look like this
https://www.dropbox.com/s/ad2arn440pu77si/test.txt
Then add a “?dl=1″ to the end of that url and a “-O filename” so that you end up with something like this:
wget https://www.dropbox.com/s/ad2arn440pu77si/test.txt?dl=1 -O test.txt
Now you can easily get files onto your linux box that aren’t available elsewhere.
