mac电脑终端怎么显示项目树：tree命令的使用

tree-command

how to use tree command on mac

Mac中tree命令使用

tree是一个能列出递归目录的命令，以图形显示驱动器或路径的文件夹结构，可以生成命令树。Windows和Linux都有，mac没有原生支持，需要安装tree或者在home目录中添加.bashrc文件里面加入：
alias tree="find . -print | sed -e 's;¹*/;|____;g;s;____|; |;g'" 。保存退出后，使用source .bashrc命令更新一下脚本资源，这是再在终端下试一下tree命令.
第二种没有试过，我们来试下比较简单的第一种吧。

# 安装Homebrew 在终端输入下面指令

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

# 安装 tree
brew install tree

在某个项目下执行tree命令即可

panzhiqiangdeMacBook-Pro:webpack2-in-action panzhiqiang$ tree -L 1

# -L 1 指只显示一级目录

.
├── README.md
├── index.html
├── index.js
├── node_modules
└── package.json

tree命令后面的参数有其他可选,具体我们可以用tree --help来查看
