~~Right. "Pure" bash would mean they somehow got sockets working in the scripting language itself, which is not possible unless you're on a system with `/dev/tcp` (which isn't many these days).~~ I am wrong! See response.

/dev/tcp is a Bash construct (mentioned as "pseudo-device file" in the manual): https://tldp.org/LDP/abs/html/devref1.html https://tldp.org/LDP/abs/html/devref1.html

  Oh huh, TIL it's only a Bash thing. I stand corrected - I thought it was a Linux thing that was removed for security reasons. Thanks for correcting me :)
