什么是zsh

ZSH也称为Z Shell，是Bourne Shell(sh)的扩展版本，具有许多新功能，并支持插件和主题。 由于ZSH与Bash基于相同的外壳，因此ZSH具有许多相同的功能，并且切换起来非常容易。

zsh的安装

• ubantu20.04下安装非常容易，直接apt install即可,然后查看系统中的全部shell中出现zsh代表安装成功

jiahui@ubuntu:~$ sudo apt install zsh

jiahui@ubuntu:~$ zsh --version
zsh 5.8 (x86_64-ubuntu-linux-gnu)

jiahui@ubuntu:~$ cat /etc/shells 
/bin/sh
/bin/bash
/bin/rbash
/bin/dash
/bin/zsh
/usr/bin/zsh

• 设置zsh为默认的shell

jiahui@ubuntu:~$ chsh -s /bin/zsh 
jiahui@ubuntu:~$ reboot 

• 查看是否已经设置称为默认的shell

jiahui@ubuntu:~$ echo $SHELL
/bin/zsh

ZSH_THEME="powerlevel10k/powerlevel10k"

相关主题的安装

要说到什么主题最好用，那当然是powerlevel10k。先来上一张主题的照片

安装方法，参照官网提示：

1. 安装推荐的字体，可选，但强烈建议。

• 下载下面4个ttf文件:
  • MesloLGS NF Regular.ttf
  • MesloLGS NF Bold.ttf
  • MesloLGS NF Italic.ttf
  • MesloLGS NF Bold Italic.ttf
• 双击文件，然后点击安装即可。
• 配置终端使用这个字体，以GNUME Terimal(默认的ubantu终端)为例：Open Terminal → Preferences and click on the selected profile under Profiles. Check Custom font under Text Appearance and select MesloLGS NF Regular.

2. 安装Powerlevel10k

• 将仓库克隆到~/.oh-my-zsh/custom/themes

╭─     ~/.oh-my-zsh/custom/themes on    master                                                                           at   14:47:39 ─╮
╰─❯ git clone https://github.com/romkatv/powerlevel10k.git 

• 修改zshrc配置文件

# 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/ohmyzsh/ohmyzsh/wiki/Themes
ZSH_THEME="powerlevel10k/powerlevel10k"

3. 使用exec Zsh重新启动Zsh

╭─     ~/.oh-my-zsh/custom/themes on    master                                                                     ✘ INT at   14:49:14 ─╮
╰─❯ exec zsh  

4. 如果配置向导没有自动启动，请键入p10k configure

╭─     ~/.oh-my-zsh/custom/themes on    master                                                                     ✘ INT at   14:52:43 ─╮
╰─❯ p10k configure 

5. 按照对应的配置向导即可完成专属自己的主题配置，如果觉得不好，请键入p10k configure重新配置
