注:此处需要 Ubuntu 上已经安装 git,如果没有安装,请先安装 git

sudo apt install -y git

如果执行上面的命令官方给的一键安装命令时出现类似如下问题,表明你所有地区的 raw.github.com raw.githubusercontent.com 已经被墙了~

Failed to connect to raw.github.com port 443: Connection refused

有两种解决方法:

(1) 第一种就是使用 github 的镜像克隆

可以是自己私有的克隆,也可以是别人提供的公有的镜像,下面以公有镜像为例:

sh -c "$(curl -fsSLhttps://raw.staticdn.net/ohmyzsh/ohmyzsh/master/tools/install.sh)"

(2) 第二种就是先把源码克隆到本地,再本地化安装

在用户可读写的任意目录执行如下命令即可进行安装,基本等于一键安装。

git clone https://github.com/ohmyzsh/ohmyzsh; sh ohmyzsh/tools/install.sh

示例:

$ git clone https://github.com/ohmyzsh/ohmyzsh; sh ohmyzsh/tools/install.sh

建议使用第二种方法进行安装,因为第一种方法使用第三方提供的镜像不知道是否稳定,说不定哪天就不支持了,而自己从 github 同步到国内的 gitee 或者自己私有的 gitlab 源再进行安装,相对来说操作步骤多且繁琐。

综合来看,推荐使用第二种方法。

4、安装 zsh-autosuggestions 插件

autosuggestions 是 zsh 的自动提示插件,可以自动提示已经输入过的命令,非常方便。此插件也可以不安装,但强烈建议安装

a、使用 git 下载 zsh-autosuggestions 插件到 ~/.oh-my-zsh/plugins 目录

cd ~/.oh-my-zsh/plugins
git clone git://github.com/zsh-users/zsh-autosuggestions

示例:

➜  plugins git:(master) cd ~/.oh-my-zsh/plugins
➜  plugins git:(master) git clone git://github.com/zsh-users/zsh-autosuggestions
Cloning into 'zsh-autosuggestions'...
remote: Enumerating objects: 11, done.
remote: Counting objects: 100% (11/11), done.
remote: Compressing objects: 100% (10/10), done.
remote: Total 2396 (delta 2), reused 3 (delta 1), pack-reused 2385
Receiving objects: 100% (2396/2396), 545.28 KiB | 481.00 KiB/s, done.
Resolving deltas: 100% (1533/1533), done.

b、配置 zsh-autosuggestions 插件

编辑 vi ~/.zshrc 文件,找到 plugins=(xxx) 这一行,添加 zsh-autosuggestions,如下示例

plugins=(git zsh-autosuggestions)

c、使用配置生效

source ~/.zshrc

5、将 shell 设置为 zsh,使用如下命令切换

正常情况下,安装成功 oh-my-zsh 后,会自动将 shell 切换到 zsh。

如果你在安装 oh-my-zsh 的时候没有选择切换 shell 到 zsh,那么你需要执行如下命令来切换。

chsh -s /bin/zsh

安装完成~

总结

1、安装校验

输入一个 git,已经提示了最近使用 git 的一条命令,只需要按一下方向键的右键即可完成此条命令的输入,非常方便:

2、卸载 oh-my-zsh

执行如下命令即可进行卸载。

uninstall_oh_my_zsh

如果执行上面的命令报错找不到 uninstall_oh_my_zsh,那么请你确保已经 source ~/.zshrc
