How to install a GNU/Linux ARM emulator

Prerequisites:

A PC with a Linux distribution - Arch Linux amd64 used here

Dependencies (for Arch Linux amd64 but very easy to get on most distros):

edk2-armvirt (or a prebuilt firmware binary from the Unofficial EDK2 nightly build project [some builds may have issues, here's a direct link to a build I confirmed to work])
qemu-arch-extra (provides the command qemu-system-aarch64)
wget (or any downloader)

ZSH CheatSheet

This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.

Strings

Description	Syntax
Get the length of a string	`${#VARNAME}`
Get a single character	`${VARNAME[index]}`

$ printf %s 'encode this'|jq -sRr @uri
encode%20this

$ jq -rn --arg x 'encode this' '$x|@uri'
encode%20this

# -r (--raw-output) outputs the raw contents of strings instead of JSON string literals. -n (--null-input) doesn't read input from STDIN.
