macOS升级到Catalina(10.15)后，终端默认的shell变成了zsh，结果发现之前配置的Git命令自动补齐功能无法使用，在搜寻其他替代解决方案时发现了Oh My Zsh，本文主要记录一下Oh My Zsh的简单使用，大神忽略。

bash是目前大多数Linux系统默认使用的shell，全名BourneAgain Shell，一共有40个命令。包含的功能几乎可以涵盖shell所具有的功能，所以一般的shell脚本都会指定它为执行路径。

从 macOS Catalina Beta 版开始，zsh (Z shell) 成为macOS下所有新建用户的默认 Shell。

我们可以通过下面命令，来查看当前系统支持的所有shell

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

Oh My Zsh是一个开源的、社区驱动用于管理zsh配置的框架。

安装

sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

# 国内代理地址
sh -c "$(curl -fsSL https://raw.fastgit.org/ohmyzsh/ohmyzsh/master/tools/install.sh)"

安装完之后，会在你的用户目录下新建两个文件：.oh-my-zsh .zshrc。.oh-my-zsh目录就是Oh-My-Zsh的项目Git克隆目录，.zshrc则是Oh-My-Zsh帮你生成的zsh配置文件。

.zshrc

主题设置

在.zshrc文件中找到主题配置项

# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes
ZSH_THEME="robbyrussell"

这里可以设置主题的名字，我们可以通过如下命令来查看Oh-My-Zsh已经存在的主题配置

ls .oh-my-zsh/themes

需要注意的是，在使用某些主题时（比如agnoster），需要安装Powerline Fonts，否则会导致终端的命令行出现?这样的符号。

插件

Oh My Zsh的.oh-my-zsh/plugins目录下存放了很多默认自带的插件，打开.zshrc配置文件，定位到plugins：

# Which plugins would you like to load?
# Standard plugins can be found in ~/.oh-my-zsh/plugins/*
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
plugins=(git)

可以看到默认只开启了git插件，如果要启用其他插件，则将要使用的插件的名字以空格相隔接在后面就可以了，比如：

plugins=(git adb)
