This article continues the previous article, introducing the beautification of WSL in the Windows terminal, of course, that is the beautification of the Linux terminal. This time using Oh my posh's origin project, oh my zsh

Prepare
Bash is the default shell for most Linux terminals. Explain the difference between the terminal and the shell in a simple way. For example, the terminal is an IDE, and the shell is a compiler. The commands you enter in the terminal are finally handed over to the shell for execution.
I use WSL as the demo Linux system, the distribution is Ubuntu 20.04 LTS. WSL can be downloaded directly from the Microsoft store, and there are detailed tutorials on the Internet for the installation method. However, if necessary, I will publish a separate tutorial later.
In order to beautify, we need to replace the default Bash with Zsh. Most of Zsh's syntax matches Bash's.
check shell
Check the installed shells by typing:
$ cat /etc/shells
Enter the following command to view the default shell (note capitalization):
$ echo $SHELL
No Zsh, needs to be installed. If you have one, you can skip the installation step.
Install Zsh
ubuntu：
sudo apt-get install zsh
After installation, don't rush to start zsh. The default configuration of zsh is very complicated, so we need to use Oh my zsh to configure zsh, which is to beautify the configuration.
Install Oh my zsh
Use the domestic gitee mirror to download the script:
wget https://gitee.com/mirrors/oh-my-zsh/raw/master/tools/install.sh
After the script is downloaded, the privilege needs to be raised, and the executable privilege is increased by using the following code:
chmod +x install.sh
implement:
./install.sh
In this step, if you find that the download is very slow, you can open and install.shmodify the image (I use VS Code, because this is the only graphical text editor available under WSL, you can change it to vim):
code install.sh
Find the following section:
Change the middle two lines to:
REPO=${REPO:-mirrors/oh-my-zsh}
REMOTE=${REMOTE:-https://gitee.com/${REPO}.git}
Save and execute again. You should see the following prompt:
beautify
change the default shell
Change the default shell to zsh:
$ chsh -s /bin/zsh
change theme
Modify the configuration file of oh my zsh:
code ~/.zshrc
Find the location as shown in the picture: 
I changed the theme to agnoster here, you can find more themes on the official website of oh my zsh, but additional downloads may be required.
Effect
The effect of agnoster is as follows:
