Linux Shell美化:oh-my-zsh

1. 查看当前shell

   echo $SHELL
   /bin/bash
   

2. 查看当前是否安装zsh

   cat /etc/shells 
   
   /bin/sh
   /bin/bash
   /usr/bin/sh
   /usr/bin/bash
   /bin/tcsh
   /bin/csh
   

3. 安装zsh

   yum install -y zsh
   

4. 设置默认shell

   chsh -s /bin/zsh
   

5. 安装oh-my-zsh 需要git

   # 如果没有git，则安装
   yum install -y git
   sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
   

6. 安装插件

   • zsh-autosuggestions

     官网。非常好用的一个插件，会记录你之前输入过的所有命令，并且自动匹配你可能想要输入命令，然后按→补全

     # 1. Clone this repository in oh-my-zsh's plugins directory:
     git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
     
     # 2. Activate the plugin in ~/.zshrc:
     plugins=( [plugins...] zsh-autosuggestions)
     

   • zsh-syntax-highlighting

     官网。命令太多，有时候记不住，等输入完了才知道命令输错了，这个插件直接在输入过程中就会提示你，当前命令是否正确，错误红色，正确绿色

     # 1. Clone this repository into $ZSH_CUSTOM/plugins
     git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
     
     
     # 2. Add the plugin to the list of plugins for Oh My Zsh to load (inside ~/.zshrc):
     plugins=( 
         # other plugins...
          zsh-syntax-highlighting
     )
     

   • sudo

     偶尔输入某个命令，提示没有权限，需要加sudo，这个时候按两下ESC，就会在命令行头部加上sudo

7. 修改主题

   • 在.oh-my-zsh/themes目录下新建一个主题my.zsh-theme,添加下面内容：

    PROMPT="
   %{$fg[cyan]%}%M(%{$fg[red]%}%n) %(?:%{$fg_bold[green]%}➜ :%{$fg_bold[red]%}➜ )"
   PROMPT+='%{$fg[cyan]%}%c%{$reset_color%}:'
   RPROMPT="%{$fg[blue]%}%T $(git_prompt_info)"
   
   ZSH_THEME_GIT_PROMPT_PREFIX="%{$fg_bold[blue]%}git:(%{$fg[red]%}"
   ZSH_THEME_GIT_PROMPT_SUFFIX="%{$reset_color%} "
   ZSH_THEME_GIT_PROMPT_DIRTY="%{$fg[blue]%}) %{$fg[yellow]%}✗"
   ZSH_THEME_GIT_PROMPT_CLEAN="%{$fg[blue]%})"
   

   这个是根据自带的主题简单修改的，关于怎么自己写自定义主题，参考我写的另一篇文章

   • 修改.zshrc文件，修改主题配置字段：ZSH_THEME="my"

   • 最后source .zshrc
