让你的zsh躁起来

近来频繁看到GitHub上分享的个人dotfile的readme页面出现一副ASCII画面主导的系统信息，仔细观察发现是Neofetch ，据官方介绍，是一种「用bash3.2+写的、基于命令行的系统信息工具」，同类的还有screenfetch。

什么是neofetch

Neofetch is a command-line system information tool written in bash 3.2+. Neofetch displays information about your operating system, software and hardware in an aesthetic and visually pleasing way.

The overall purpose of Neofetch is to be used in screen-shots of your system. Neofetch shows the information other people want to see. There are other tools available for proper system statistic/diagnostics.

如何安装neofetch

以macOS为例，如果你安装了Homebrew，那么16个字符就能轻松搞定

$ brew install zsh

完成后就可以运行neofetch命令了，但为了让neofetch能随zsh启动，先修改zsh配置

$ vi ~/.zshrc

在你的zsh启动主题后面添加neofetch(另一种写法是末尾加载)

 # 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/robbyrussell/oh-my-zsh/wiki/Themes
 ZSH_THEME="ys"
 neofetch

也可以前置一个判断逻辑：

1 - » 获取neofetch路径

which neofetch

2 - » 在zsh配置中加载

if [ -x /usr/bin/neofetch ]
then
    /usr/bin/neofetch
fi

好了，重启zsh就可以看到效果了。

如何配置neofetch

如果需要个性化定制配置文件，修改如下文件：

$ vi ~/.config/neofetch/config.conf

基本设置信息如下,需要开启哪一项，就将前面的注释符#去掉：

print_info () {
    info title
    info underline

    info "Host" model
    info "OS" distro
    info "Kernel" kernel

    # The lines below with a '#' in front are additional info functions
    # that are disabled by default. Removing the '#' enables them and adding
    # a '#' to the start disables them again. You can add a '#' to any of the
    # lines in this function to disable their output.

    # info "CPU Usage" cpu_usage

很多人关心如何替换默认的ASCII logo，比如将苹果logo替换为xubuntu logo，输入：
