Does it work on fish shell?
What that garble of symbols does, is that it defines and calls a function named
:, which calls itself twice.The syntax for defining a function is different in Fish, so no, this particular garble will not work:
But it is, of course, possible to write a (much more readable) version that will work in Fish.
you can write a more readable version in any shell, it's intentionally unreadable
Yeah, I meant, as an attacker, you couldn't come up with a similarly unreadable version.
At least, as far as I can tell, defining a function requires spelling out
functionand seems to require being defined on multiple lines, too.Oh, I see. That's very nice then
Unfortunately it works in zsh. I just had to kill my laptop after curiosity got the better of me.
