Tmux 快捷键 & 速查表

启动新会话：

tmux [new -s 会话名 -n 窗口名]

恢复会话：

tmux at [-t 会话名]

	var table = document.getElementById('abc');
	var text = "";
	var rowLength = table.rows.length;
	var cell1,cell2 = 0;

	for(var i=0; i<rowLength; i+=1){
	var row = table.rows[i];

	//your code goes here, looping over every row.
	//cells are accessed as easy

	#! /bin/bash
