How to Change Open Files Limit on OS X and macOS

This text is the section about OS X Yosemite (which also works for macOS Sierra) from https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/#mac-os-x

The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/

Mac OS X

To check the current limits on your Mac OS X system, run:

Proxmox PVE 6.x Post Installation Steps

This cheatsheet helps to set up your Proxmox Virtual Environment (PVE) host after fresh installation. Designed and tested on PVE version 6.x.

Note about sudo

I do not prepend sudo command to any of commands listed here, but keep in mind that nearly all commands requires su privileges, so use sudo if your account happen to not have root access.

How to edit config files

The simplest way to edit config file is to use vim.tiny editor, for example to edit vzdump.conf file use this command:

	#!/usr/bin/env bash

	set -euo pipefail

	# install-duf-latest-deb.sh
	# - Downloads and installs the latest duf (https://github.com/muesli/duf) release from github
	# - Tested for Ubuntu & Debian running on amd64 & armhf

	# Enable xtrace if the DEBUG environment variable is set
	if [[ ${DEBUG-} =~ ^1\|yes\|true$ ]]; then

	#!/usr/bin/env bash

	set -euo pipefail

	# histdump.sh
	#

	HOME=${HOME:-'/root'}

	arg1=${1:-}

	#!/usr/bin/env bash

	set -euo pipefail

	# Ask for the user password
	# Script only works if sudo caches the password for a few minutes
	sudo true

	# Install kernel extra's to enable docker aufs support
	# sudo apt-get -y install linux-image-extra-$(uname -r)

	# CCZE Colourize Config for Ubuntu
	# http://lintut.com/colorize-log-files-on-linux-using-ccze-tool/
	# http://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/

	CCZE=`which ccze`
	if [[ "$TERM" != dumb ]] && [[ -n "$CCZE" ]]; then
	function colourify { $@ \| $CCZE -A; }
	alias colourify=colourify

	alias configure='colourify ./configure'

	#!/usr/bin/env bash

	# Setup script environment
	set -o errexit #Exit immediately if a pipeline returns a non-zero status
	set -o errtrace #Trap ERR from shell functions, command substitutions, and commands from subshell
	set -o nounset #Treat unset variables as an error
	set -o pipefail #Pipe will exit with last non-zero status if applicable
	shopt -s expand_aliases
	alias die='EXIT=$? LINE=$LINENO error_exit'
	trap die ERR

	#!/usr/bin/env bash

	set -euo pipefail

	# brew-install-dublin-traceroute--HEAD-with-root-setuid.sh
	#

	# Ask for sudo password here instead of after building dublin-traceroute, for convenience.
	sudo -v

	#!/usr/bin/env bash

	set -e
	set -x

	brew install signal-cli

	SIGNAL_LIBEXEC_LIBDIR="`brew --prefix signal-cli`/libexec/lib"

	# zkgroup-java*.jar --- remove the linux x86_64 bundled lib

	# Allow rmate to work without parameters
	AcceptEnv RMATE_*
