tail -fみたいに流しながら見たいんだけど、色んなコマンドが出力をバッファしちゃうので、困ったときはそのコマンドにバッファしないオプションが無いか探すのがオヌヌメ。 man command -> bufferとかで検索

grep

   --line-buffered
          Use line buffering, it can be a performance penality.

$ iostat -x 1 | grep --line-buffered 'sda'

	#!/bin/sh
	# Just copy and paste the lines below (all at once, it won't work line by line!)
	# MAKE SURE YOU ARE HAPPY WITH WHAT IT DOES FIRST! THERE IS NO WARRANTY!

	function abort {
	echo "$1"
	exit 1
	}

	set -e

	A script to query the Amazon Web Services usage reports programmatically.

	Ideally this wouldn't exist, and Amazon would provide an API we can use
	instead, but hey - that's life.

	Basically takes your AWS account username and password, logs into the
	website as you, and grabs the data out. Always gets the 'All Usage Types'
