neofetch是一个命令行工具，可以用来显示系统的基本信息和硬件配置。它支持多种操作系统，包括Linux、macOS和Windows等。
检查本地操作系统版本
[root@jeven ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
检查系统内核版本
[root@jeven ~]# uname -r
3.10.0-957.el7.x86_64
curl -o /etc/yum.repos.d/konimex-neofetch-epel-7.repohttps://copr.fedorainfracloud.org/coprs/konimex/neofetch/repo/epel-7/konimex-neofetch-epel-7.repo
[root@jeven ~]# yum repolist all |grep enable

sudo apt-get install neofetch # Debian/Ubuntu
sudo pacman -S neofetch # Arch Linux
brew install neofetch #macos
yum install neofetch -y
查看neofetch版本
[root@jeven ~]# neofetch --version
Neofetch 6.1.0
直接使用neofetch命令，
这将显示操作系统和计算机的相关信息，例如系统名称、内核版本、主机名、CPU型号、内存、GPU等等。
neofetch
--ascii：使用ASCII字符来表示系统图标
--color_blocks：使用彩色的块来表示系统信息
--kernel_shorthand：使用更简短的方式来表示内核版本
--off：关闭某些特定的信息显示，例如标志、操作系统等
--cpu：展示CPU信息
--gpu：展示GPU信息
--memory：展示内存信息
--disk：展示磁盘信息
--uptime：展示系统运行时间
--kernel：展示内核版本信息
--shell：展示Shell信息
--de：展示桌面环境信息
--wm：展示窗口管理器信息
neofetch的配置文件位置默认在$HOME/.config/neofetch/config.conf
可以自定义根据需要修改。

更改输出颜色

默认情况下，neofetch 显示当前发行版的 Logo。但是可以设置输出不同发行版的 ASCII Logo。
neofetch --ascii_distro arch
导出neofetch输出：
有时我们希望将neofetch输出保存到文件中。要将neofetch输出保存到文件中，请使用以下命令：
neofetch > info_system.txt
[root@jeven ~]# cat info_system.txt
.. root@jeven
