Ubuntu平铺左、右、上、下、1/2、1/4窗口（脚本）

前言

之前因为一直在用Ubuntu 18或者Ubuntu 20然后发现装了GNOME插件后，电脑在使用过程中，会时不时的卡死（鼠标没问题，键盘输入会有10-20秒的延迟）频率基本是一小时一次，因为这种卡顿会很容易打断思路，所以我重装了系统，从最小化安装开始，什么软件都经过我一手安装了（没有安装GNOME插件）发现没有卡顿的现象了（初步排查是GNOME插件的问题）。

所以就有了这篇用脚本实现窗口平铺的文章。如何你们用插件没有这个BUG那么可以直接下载GNOME- WinTile插件就可以实现了。

创建脚本文件/usr/local/bin/ubuntu_move_windows，内容如下：

#!/bin/bash

unset key
unset file
unset directory

	half_wid=$(expr $wid / 2)
	half_hei=$(expr $hei / 2)
else
	half_wid=$(expr $wid / 4)
	half_hei=$(expr $hei / 2)
fi
