什么是HomeBrew
使用Homebrew安裝 Apple（或您的 Linux 系統）沒有預裝但 你需要的東西。
安裝HomeBrew
1.1將brew的install文件下載本地
cd ~ && curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install >> brew_install
1.2修改install文件的鏡像源
# BREW_REPO = "https://github.com/Homebrew/brew".freeze
BREW_REPO = "git://mirrors.ustc.edu.cn/brew.git".freeze
1.3安裝brew
/usr/bin/ruby ~/brew_install
1.4驗證是否安裝成功
$ brew doctor
如果沒成功先卸載brew一下，再試
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
如何使用 HomeBrew 安裝軟件
安裝完 HomeBrew 后可使用以下命令進行軟件包安裝：
brew install 軟件名稱HomeBrew 常用命令
$ brew --help # 查看簡潔幫助
$ man brew # 完整命令幫助
$ brew install [name] # 安裝軟件包
$ brew uninstall [name] # 卸載軟件包
$ brew search [name] # 搜索軟件包
$ brew list # 顯示已經安裝的所有軟件包
$ brew update # 同步遠程最新更新情況，對本機已經安裝並有更新的軟件用*標明
$ brew outdated # 查看已安裝的哪些軟件包需要更新
$ brew upgrade [name] # 更新單個軟件包
$ brew info [name] # 查看軟件包信息
$ brew home [name] # 訪問軟件包官方站
$ brew cleanup # 清理所有已安裝軟件包的歷史老版本
$ brew cleanup [name] # 清理單個已安裝軟件包的歷史版本
HomeBrew中安裝的好用的三方軟件
wget
1、安裝wget
安裝命令：brew install wget
檢驗是否安裝成功：
安裝成功后結果如下：
MacBook-Pro:~ home$ wget http://www.arefly.com/
--2020-06-02 14:46:12-- http://www.arefly.com/

Zsh 入門(安裝及使用)
先看下你的 CentOS 支持哪些 shell：cat /etc/shells，正常結果應該是這樣的：
MacBook-Pro:~ dunk$ cat /etc/shells # List of acceptable shells for chpass(1). # Ftpd will not allow users to connect who are not using # one of these shells. /bin/bash /bin/csh /bin/dash /bin/ksh /bin/sh /bin/tcsh /bin/zsh
默認 CentOS / Ubuntu / Mac 系統用的是 Bash，倒也不是說 Bash 不好，而是說我們有更好的選擇。
Zsh 安裝
- CentOS 安裝：
sudo yum install -y zsh Ubuntu 安裝：sudo apt-get install -y zsh在檢查下系統的 shell：cat /etc/shells，你會發現多了一個：/bin/zsh
使用 Zsh 擴展集合：oh-my-zsh
什么是Oh My Zsh
Oh My Zsh是一款社區驅動的命令行工具，正如它的主頁上說的，Oh My Zsh 是一種生活方式。它基於zsh命令行，提供了主題配置，插件機制，已經內置的便捷操作。給我們一種全新的方式使用命令行。
Oh My Zsh這個名字聽起來就很有意思，它是基於zsh命令行的一個擴展工具集，提供了豐富的擴展功能。
Oh My Zsh只是一個對zsh命令行環境的配置包裝框架，但它不提供命令行窗口，更不是一個獨立的APP。
- oh-my-zsh 幫我們整理了一些常用的 Zsh 擴展功能和主題：https://github.com/robbyrussell/oh-my-zsh
- 我們無需自己去搗搞 Zsh，直接用 oh-my-zsh 就足夠了，如果你想繼續深造的話那再去弄。
- 先安裝 git：
sudo yum install -y git - 安裝 oh-my-zsh
-
Basic Installation Oh My Zsh is installed by running one of the following commands in your terminal. You can install this via the command-line with either curl or wget. via curl sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" via wget
// 這里使用 wgetsh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
- 在以 root 用戶為前提下，oh-my-zsh 的安裝目錄：/root/.oh-my-zsh
- 在以 root 用戶為前提下，Zsh 的配置文件位置：/root/.zshrc
- 為 root 用戶設置 zsh 為系統默認 shell：
chsh -s /bin/zsh root 注意：這里安裝的時候會有Do you want to change your default shell to zsh? [Y/n] 的選擇，寫Y然后回車就可以
- 如果你要重新恢復到 bash：
chsh -s /bin/bash root - 現在你關掉終端或是重新連上 shell，現在開頭是一個箭頭了，如下圖：
-
Oh My Zsh目錄結構
進入~/.oh-my-zsh目錄后，看看該目錄的結構
lib 提供了核心功能的腳本庫
tools 提供安裝、升級等功能的快捷工具
plugins 自帶插件的存在放位置
templates 自帶模板的存在放位置
themes 自帶主題文件的存在放位置
custom 個性化配置目錄，自安裝的插件和主題可放這里
Zsh 配置
插件
- 啟用 oh-my-zsh 中自帶的插件。
- oh-my-zsh 的插件列表介紹（太長了，用源碼不精准地統計下有 149 個）：https://github.com/robbyrussell/oh-my-zsh/wiki/Plugins
- 編輯配置文件：
vim /root/.zshrc，找到下圖的地方，怎么安裝，原作者注釋寫得很清楚了，別裝太多了，默認 git 是安裝的。
git 自動顯示當前分支名稱和修改狀態
git 快捷鍵
https://github.com/ohmyzsh/ohmyzsh/blob/master/plugins/git/git.plugin.zsh
zsh幫我們配置了一些git的常常用命令簡寫，我常用的是幾個命令
gst 代表 git status
# 添加當前目錄的所有文件到暫存區 alias ga . ='git add .'
# 提交暫存區到倉庫區 alias gcmsg ='git commit -m'
# 提交工作區自上次commit之后的變化，直接到倉庫區 gca 代表 git commit -v -a'
# 提交 alias gp ='git push'
# 切換到指定分支，並更新工作區 gco 代表 git checkout
# 列出所有本地分支 alias gb ='git branch'
# 列出所有本地分支和遠程分支 alias gba ='git branch -a'
進入 ~/.zshrc配置文件，先給看下我的配置，可以憑自己喜好更改：
vim ~/.zshrc

默認是只有git
plugins=(git)
新增插件舉例
- 安裝zsh-syntax-highlighting語法高亮插件
下載插件
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git echo "source ${(q-)PWD}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh" >> ${ZDOTDIR:-$HOME}/.zshrc
編輯激活 ~/.zshrc配置文件
plugins=(git zsh-syntax-highlighting )
保存后 source一下，讓改變生效
source ~/.zshrc
發現再敲命令就有顏色了，比如命令有誤的時候是紅色，命令正確的時候是綠色。
軟件安裝位置：cd ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions
oh my zsh 手動更新，可以執行
upgrade_oh_my_zsh
卸載oh my zsh
直接在終端中，運行uninstall_oh_my_zsh既可以卸載。
備注：
插件可以裝很多，但是裝多了之后會在每次進入命令提示符的時候明顯變慢。慎用。
