一些可能会用到，但老记不住的 Linux 命令
# 查看Linux的发行版本
lsb_release -a
uname -a
cat /etc/issue
cat /proc/version
# 列出本地已经安装了的 package

shhider / sed 命令在 macOS 下的使用.md
Created August 24, 2017 09:00

sed 命令在 macOS 下使用存在两个问题：

-i参数之后必须带参数值

-i参数表示直接对文件进行操作，可提供一个参数值作为后缀名，使 sed 在替换前对文件进行备份，如sed -i ".bak" "s/aaa/bbb/g" filename。这个在 macOS 下必需，不需要备份的传空。

可能会出现编码问题

执行命令后，可能出现sed: RE error: illegal byte sequence的报错。

if (x === undefined) { ... }

不严谨，undefined 关键字是可以被更改的。
