Oh My Zsh Installation

1. List item download

• curl $ sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
• wget $ sh -c "$(wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"

2. Catalog introduction

In fact, the above installation is just to download the git repository of oh my zsh. After entering the ~/.oh-my-zsh directory, look at the structure of the directory

$ ls .oh-my-zsh
CODE_OF_CONDUCT.md README.md          lib                plugins            tools
CONTRIBUTING.md    cache              log                templates
LICENSE.txt        custom             oh-my-zsh.sh       themes

• lib provides the script library for the core functionality
• tools Provide shortcut tools for installation, upgrade and other functions
• plugins The location where the built-in plugin exists
• templates The existence of the built-in template
• where themes comes with the theme file
• custom personalized configuration directory, self-installed plugins and themes can be placed here

For this configuration, we only need to care about pluginsand themestwo directories, you can enter these two directories to see which plugins and themes oh my zsh provides by default.
See what plugins are included

$ ls ~/.oh-my-zsh/plugins

adb                      debian                   git-flow                 last-working-dir         profiles                 systemd
alias-finder             dircycle                 git-flow-avh             lein                     pyenv                    taskwarrior
ansible                  direnv                   git-hubflow

3den.zsh-theme                 gallifrey.zsh-theme            nebirhos.zsh-theme
Soliah.zsh-theme               gallois.zsh-theme              nicoulaj.zsh-theme

3. Theme configuration

Modify the .zshrc file, ~/.oh-my-zsh/themesfind the theme you want to use from the directory, and configure the theme name to the value of ZSH_THEME as the key in the .zshrc file.

Only one topic can be configured, and the format is as follows:

ZSH_THEME="themeName"

I am using the theme ys.zsh-theme. When configuring, you need to omit the following .zsh-theme, namely ys, as follows:

3.1 Edit the .zshrc file

vim ~/.zshrc

3.2 Modify the theme

ZSH_THEME="ys"

3.3 Effective

source ~/.zshrc 

You can also use the random theme

ZSH_THEME="random"

It means that every time you open the terminal, you will use a theme at random until you see which theme looks good that day. Use the echo command to output the name of the current theme, and then change it to the theme you like.

$ echo $ZSH_THEME

4. Plug-in configuration

Similar to the configuration topic above, modify .zshrcthe file, ~/.oh-my-zsh/pluginsfind the plug-in you want to use from the directory, and configure the plug-in name to the value of .zshrckey in the file . Multiple plugins can be configured in the following format:plugins

 plugins=(plugin1 plugin2 plugin3)

4.1 Edit the .zshrc file

vim ~/.zshrc

4.2 Fill in the required plug-ins

plugins=(git zsh-autosuggestions zsh-syntax-highlighting web-search)

4.3 Entry into force

source ~/.zshrc 

5. Extension plug-in

使用扩展的插件，需要把对应的插件下载到 ~/.oh-my-zsh/plugins文件夹中，然后修改.zshrc文件，把该插件名填入到plugins的位置；

5.1 Autocommand Prompt zsh-autosuggestions

• Function: When you enter a command in the terminal, the command you entered before will automatically appear. At this time, press the → key to complete the command.
  This is not a plugin that comes with oh my zsh, it needs to be downloaded to the plugin directory (~/.oh-my-zsh/plugins)
• Get the plugin:

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

• Enable the plugin: modify the ~/.zshrc file, and add the name of the plugin after the value in plugins.

plugins=(省略之前的插件名称 zsh-autosuggestions)

5.2 Syntax highlighting zsh-syntax-highlighting

• Function: The input commands such as ls, cd will become highlighted color
• Get the plugin:

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ~/.oh-my-zsh/plugins/zsh-syntax-highlighting

• Enable the plugin: modify the ~/.zshrc file, and add the name of the plugin after the value in plugins.
  plugins=(omit the previous plugin name zsh-syntax-highlighting)

5.3 Code completion zsh-completions

• Function:
• Get the plugin:

  git clone https://github.com/zsh-users/zsh-completions ${ZSH_CUSTOM:=~/.oh-my-zsh/custom}/plugins/zsh-completions

• Enable the plugin: modify the ~/.zshrc file, and add the name of the plugin after the value in plugins.
