linux zsh终端美化

目前的centos系统默认的shell还是bash，但是zsh被称为终极shell，国外有个程序员开发出了一个能够让你快速上手的zsh项目，叫做「oh my zsh」，Github 网址是：https://github.com/robbyrussell/oh-my-zsh 有了这玩意zsh用起来直接就变成神器了。

查看系统当前的shell

echo $SHELL

返回的结果是:

/bin/bash

查看bin下是否有zsh包

cat /etc/shells
**********************************************
返回的结果是:
/bin/sh
/bin/bash
/sbin/nologin
/usr/bin/sh
/usr/bin/bash
/usr/sbin/nologin

PS.默认没有安装zsh

zsh

安装

sudo yum install -y zsh

然后在输入cat /etc/shells查看

/bin/sh
/bin/bash
/sbin/nologin
/usr/bin/sh
/usr/bin/bash
/usr/sbin/nologin
/bin/zsh

配置

将zsh设置成默认的shell

chsh -s /bin/zsh

设置完以后不会立即生效，需要重启终端方能生效
查看版本

zsh --version
**********************************************
返回的结果是:
zsh 5.0.2 (x86_64-redhat-linux-gnu)

oh-my-zsh

安装

通过 GitHub安装容易出现安装失败的情况，所以我们采用 gitee 镜像仓库来安装

wget https://gitee.com/Devkings/oh_my_zsh_install/raw/master/install.sh -O - | sh

出现以下界面就表示安装成功了

         __                                     __
  ____  / /_     ____ ___  __  __   ____  _____/ /_
 / __ \/ __ \   / __ `__ \/ / / /  /_  / / ___/ __ \
/ /_/ / / / /  / / / / / / /_/ /    / /_(__  ) / / /
\____/_/ /_/  /_/ /_/ /_/\__, /    /___/____/_/ /_/
                        /____/                       ....is now installed!


Please look over the ~/.zshrc file to select plugins, themes, and options.

我比较喜欢的是agnoster这个主题
修改文件.zshrc

ZSH_THEME="agnoster"

更新配置文件

source .zshrc

就生效了

当然也可以参考推荐：Slant - What’s the best theme for Oh My Zsh?
最火的莫过于Powerlevel10 k 了,但是 zsh 必须是 5.1 以上版本

安装Powerlevel10k

手动安装

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

国内用户可以使用 gitee上的官方镜像加速下载.

git clone --depth=1 https://gitee.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

Powerlevel10k 配置
编辑 .zshrc 文件， 文件路径 ~/.zshrc

vim ~/.zshrc
# 修改
ZSH_THEME="powerlevel10k/powerlevel10k"

Powerlevel10k 需要进行一些样式的设置，执行source .zshrc更新配置后,首次会进入样式设置引导，后期也可以通过命令

 p10k configure

去修改设置。
