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 function and 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.

The ampersand looks very weird in that font. It would bug me.

[–] [email protected] 1 points 9 months ago* (last edited 9 months ago)

It hails back to the early days of the ampersand, from when it was basically still just Latin "et": https://commons.wikimedia.org/wiki/File:Trebuchet_MS_ampersand.svg

Personally, I do like this font (Fira Mono+Sans), because it still looks professional, without being so boring that I get depression from looking at it.
But yeah, that ampersand is pushing it a bit, as I'm not sure everyone else knows that's an ampersand...
