I'm currently trying to curl some raw text and have it displayed with interpreted ANSI colours in the Terminal.

Currently, when I run curl http://example.com/test.txt (not the actual URL), it simply returns:

\033[0;31mTEST\033[0m

This is not what I am looking for; what I expected to be returned is what I see when I run echo -e "\033[0;31mTEST\033[0m", which returns TEST, coloured in red.

My question is: is there a way of making curl interpret ANSI colour codes in order to have the colours properly displayed in the Terminal as you would expect when using echo -e?

    Just out of curiosity, why use curl here? I mean, it's a tool for the HTTP protocol, and you're dealing with ANSI escape codes for the terminal. I feel like I'm missing a connection here. – Haxiel Feb 11 at 16:26

    @Haxiel Interestingly enough, I'm trying to add a sort of easter egg to a poster at my college, where echo -e "$(curl -s http://example.com/test.txt)" is in small print, and if they find the message they win a prize. – Rocco Feb 11 at 17:08

Not sure if this is the best way to do it, but using command substitution seems to work fine (even if it is a bit bulky):

echo -e "$(curl -s http://example.com/test.txt)"

Hopefully that's helpful for people in the future. Note that you can use curl -sL if you are dealing with a shortened URL.

Are you sure you are putting the raw escape sequences in the txt file? I tried it with curl-7.52.1 using both netcat and apache, and in both cases curl splatted out the escape sequence correctly to make the word colored red on my terminal.

Try this,

echo $'\e[0;31mTEST\e[0m' | nc -l -p 8080 -q0
curl localhost:8080
