linux - how to download dropbox files using wget command?

Seems I can only download dropbox files using explorer such as chrome and firefox. If I use wget to download, then I would get a file which is in html format. Why?

For example you can open this link

You would not get the content of this file, why? The following is part of test.txt to download it, this is not the content of test.txt at all.

So is it possible to download Dropbox files using wget rather than explorer?

document.observe('script:loaded', function() {
SharingModel.init('test\x2etxt', Util.from_json('\x7b\x22item\x5fid\x22\x3a\x20\x22\x22\x2c\x20\x22secure\x5fhash\x22\x3a\x20\x22\x22\x2c\x20\x22subpath\x22\x3a\x20\x22\x22\x2c\x20\x22tkey\x22\x3a\x20\x22mx9eqve5l2ipgyk\x22\x7d'))
SharingModel.init_file()
$('emsnippet-9911dfc627e1d541').innerHTML = 'test\x2etxt'.em_snippet(50, 0.750).escapeHTML();
$('emsnippet-add7879f5d805012').innerHTML = 'test\x2etxt'.em_snippet(20, 0.750).escapeHTML();
$('emsnippet-981ac0639529f983').innerHTML = 'test\x2etxt'.em_snippet(20, 0.750).escapeHTML();
FilePreview.init_text('https\x3a\x2f\x2fdl\x2edropbox\x2ecom\x2fs\x2fmx9eqve5l2ipgyk\x2ftest\x2etxt', 0)                        });
                    } else if (window.jQuery) {
jQuery(function () {

SharingModel.init('test\x2etxt', Util.from_json('\x7b\x22item\x5fid\x22\x3a\x20\x22\x22\x2c\x20\x22secure\x5fhash\x22\x3a\x20\x22\x22\x2c\x20\x22subpath\x22\x3a\x20\x22\x22\x2c\x20\x22tkey\x22\x3a\x20\x22mx9eqve5l2ipgyk\x22\x7d'))
SharingModel.init_file()
$('emsnippet-9911dfc627e1d541').innerHTML = 'test\x2etxt'.em_snippet(50, 0.750).escapeHTML();
$('emsnippet-add7879f5d805012').innerHTML = 'test\x2etxt'.em_snippet(20, 0.750).escapeHTML();
$('emsnippet-981ac0639529f983').innerHTML = 'test\x2etxt'.em_snippet(20, 0.750).escapeHTML();
FilePreview.init_text('https\x3a\x2f\x2fdl\x2edropbox\x2ecom\x2fs\x2fmx9eqve5l2ipgyk\x2ftest\x2etxt', 0)                        });
                    } 

I cannot get test.txt with command

wget https://www.dropbox.com/s/mx9eqve5l2ipgyk/test.tx


ls -l

Answer

The link in your question is not the link to the file, is a link to the Dropbox page of this file.
If you want to use wget to download it, you should copy the link to direct download from the menu that drops when pushing the download button to the right.

In my case, that worked fine.
However, sometimes problems in downloading links from outside the browser relate to parameters other than the link itself. A common element that does not exist when you simply copy the link are the site cookies.

Try this cool FF add-on to get the correct wget links

And also, especially if we are talking about a known workstation and not a casual one, you can of course install the Dropbox client. This will be the easiest way, just let your box be part of your file structure and eliminate the need of complicated downloads.
See this askubuntu.com post, and the Dropbox download page.
