安装 Zsh,并使用 Oh My Zsh

Zsh 是什么

shell 俗称壳,c 语言编写的命令解析器程序,是用户使用 linux 的桥梁。Linux/Unix 提供了很多种 Shell。常用的 Shell 有这么几种,sh、bash、csh 等。可以通过以下命令,查看系统有几种 shell:

1
$ cat /etc/shells

目前常用的 Linux 系统和 macOS X 系统的默认 Shell 都是 bash。但是真正强大的 Shell 是深藏不露的 zsh,史称『终极 Shell』,由于与 bash 相似,功能又有所加强,zsh 在 Linux 社区获得了关注。但因配置过于复杂,所以初期无人问津。直到国外有个程序员开发出了一个能够快速上手的 zsh 项目,叫做「Oh My Zsh」,Github 网址是:https://github.com/ohmyzsh/ohmyzsh

安装 zsh

撸了个安装脚本,传送门 -> Github

#方法一:wget方式自动化安装oh my zsh:
sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

#方法二:
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

#官网上的另外一种写法
curl -Lo install.sh https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
sh install.sh

  2. Activate the plugin in ~/.zshrc:

    1
    plugins=( [plugins...] zsh-syntax-highlighting)
