Returns HTML instead of plain-text

On MacOS curl cht.sh returns normal HTML page for me instead of a plain text version of the cheatsheet, however curl -q cht.sh works fine.

Yes, the problem in your case is that curl uses this User-Agent string (so it is seen as Mozilla from the web server side). I don’t know why there is such a problem in Mac OS X, but maybe is is configured by default in ~/.curlrc. Could you please check it? Probably it is the case because it works with -q. So please check your ~/.curlrc and remove the user agent line from there. If you need it for some reasons, we can override user agent in the cht.sh script explicitly (but in that case you couldn’t query the service with curl alone).

I would remove the user-agent string from your ~/.curlrc if you do not really need it.

Could you please check what user-agent uses your curl?

$ curl -vI rate.sx 2>&1 | grep User-Agent
> User-Agent: curl/7.52.1
