What user agent string is your curl request sending out?

I think it does user agent checking to decide whether to send out a shell escaped version of the page or one with traditional web markup because when I make a HTTP request with one of my other CLI HTTP clients it only sends shell output if I send curl's UA.

Which curl version do you have? Might it be a chance that you have a curl script somewhere in your PATH before real curl which enforces some user-agent setting?

Your curl user agent is most probably set to a browser user agent.

Try changing it to the curl user agent:

    curl -A "curl/7.37.0" cht.sh

Weird. Did you file a bug?

    curl cht.sh
    curl cht.sh/apt-get

The above just works for me with curl.

post a

    curl -v cht.sh
