Reminds me of my rather memorable introduction to special characters invoking functions, seeing this dastardly little quip in the email signature of someone in a mailing list (circa '95 or so).

    :(){:|:&};:
My curiosity piqued, I pasted it into the shell on my terminal in a pure example of FAFO. The poor little Sparc 5 I was using ground to a halt over the course of about ten seconds. The reboot was as hard as the lesson. xD

In college I took a database class, it was pretty basic overall as I had been playing with MySQL for a few years at that point. On the final exam I got a 90/100. The test was 10 questions that just had you write SQL to answer the question. I got all the queries 100% correct... except... I didn't put a ";" after each query. On a written test. I'm still a little bitter about that.

The ultimately sad part was the professor in a Sun OS machine. In a corner with no where to go, giving demerits because his bash was older than he realized. Reminds me of my college professor that claimed you don’t have to close HTML tags (some you absolutely do) and I proved that you do. Not all of them, but most of them. (Netscape Navigator Days)

It doesn’t have anything to do with bash (though modern bash may use a built in for `[`). He don’t have the `[` program (usually linked to `test`).

Which is why later versions of bash have a builtin…

Precisely because those older systems didn’t link to it!

So my comment still stands.

I have this printed on a sweatshirt - it saddens me a little that people who get it are so few and far between these days :'(

such nostalgia. There was a time when you could tell a fair bit about someone if that was in their email signature.
