ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Cherry pick multiple commits from a remote or upstream branch into your local branch.

git fetch upstream
git cherry-pick A^..B

start new:

tmux

start new with session name:

tmux new -s myname

(C-x means ctrl+x, M-x means alt+x)

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

	function switchgo() {
	version=$1
	if [ -z $version ]; then
	echo "Usage: switchgo [version]"
	return
	fi

	if ! command -v "go$version" > /dev/null 2>&1; then
	echo "version does not exist, download with: "
	echo " go get golang.org/dl/go${version}"

	# Requirements
	# debian/ubuntu

	apt-get -y update && apt-get -y upgrade
	apt-get -y install strongswan xl2tpd libstrongswan-standard-plugins libstrongswan-extra-plugins

	VPN_SERVER_IP=''
	VPN_IPSEC_PSK='y'
	VPN_USER=''
	VPN_PASSWORD=''

	package main

	import (
	"fmt"
	"reflect"
	)

	// Name of the struct tag used in examples
	const tagName = "validate"

	ZigZag-Encoding
	---------------

	Maps negative values to positive values while going back and
	forth (0 = 0, -1 = 1, 1 = 2, -2 = 3, 2 = 4, -3 = 5, 3 = 6 ...)

	(i >> bitlength-1) ^ (i << 1)

	with "i" being the number to be encoded, "^" being
	XOR-operation and ">>" would be arithemtic shifting-operation

	docker logs nginx 2>&1 \| grep "127."
