How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

	# IFS set
	a='111\|222\|333'
	OIFS=$IFS; IFS="\|"; set -- $a; aa=$1;bb=$2;cc=$3; IFS=$OIFS
	echo $aa $bb $cc
	111 222 333

	#eval
	s='a=22;b=33;c=44;d=5'
	eval $s
	echo $a $c $b $d

	#!/bin/sh

	# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
	# CREATE block and create them in separate commands _after_ all the INSERTs.

	# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
	# The mysqldump file is traversed only once.

	# Usage: $ ./mysql2sqlite mysqldump-opts db-name \| sqlite3 database.sqlite
	# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase \| sqlite3 database.sqlite


	# `.` = document, `[]` = foreach
	docker ps --format "{{json .}}" \|yq -pjson '.\|del(.Labels)\|{"Names":.Names, "ID":.ID,"img":.Image}\|[.]'
