- drannex 9y agoNow that's what I'm talking about.
- tekknolagi 9y agoWhat is this supposed to look like? For me it was a lot of random colors.
- sp332 9y agoIt's a bash script. Execute it and it shows a dancing woman. Edit: ok the bash thing is a red herring. It works if you just "cat lady".
- rijoja 9y agowell a shell command if you can excuse my nitpicking. Had it been a bash script he wouldn't only have made a really nice easter egg but also found a security hole in curl.

- rijoja 9y agoyou are right, I started out with piping it into less, to see if you are right and damn it if you are not right. I thought he did something with delays in the output. How and why does this work?
- idsout 9y agoANSI escape sequences. Your terminal interprets them like move cursor to row x, column y. Set color green. Etc. https://en.wikipedia.org/wiki/ANSI_escape_code https://en.wikipedia.org/wiki/ANSI_escape_code
- rijoja 9y agoInteresting? but why does bash execute the code from standard output instead of simply displaying it to the user?
- sp332 9y agoIt's not bash. You can remove the shebang line and cat the file, and it still works. It's simply your terminal interpreting the ANSI codes and displaying the contents of the file.
- rijoja 9y agoImpressive!
- _lce0 9y agowat it just started to run. I thought it was supposed to be piped for bash to be executed. Are all `curl` just exposed to bash injections?
- jwilk 9y agoNo.
- chungy 9y agoScroll up. There's no tricks here.
- _lce0 9y agoSo are you saying that bash is not actually executed but the characters are being printed on the screen and they looks as if the animation were still playing? What I cannot understand from that explanation is how the animation time works. It should display the animation in chunks, with really fast frames, followed by pauses while it waits for data to be received.
- tdeck 9y agoWithout downloading it (on my phone), I expect there are ANSI codes involved to move the cursor and control other aspects of the terminal: https://en.wikipedia.org/wiki/ANSI_escape_code?wprov=sfla1 https://en.wikipedia.org/wiki/ANSI_escape_code?wprov=sfla1
- woodrowbarlow 9y agocurl always goes to stdout if you don't redirect it. i'd guess the file is just padded so that the "animations" take longer.
- slyzmud 9y agoDo somebody know how the images where created? I haven't found a tool that creates ascii art with that color quality.
- woodrowbarlow 9y agoor does anyone know of any other examples? i want to show this to my coworkers but this particular animation is a little lewd to be bringing into work.
