Centos Stream安装neofetch及其使用教程

今天给大家分享一款Linux系统上的可以快捷查看设备系统信息的软件，即，neofetch。通过该软件，可以很方便的查询自己系统的信息及运行的状况，包括CPU、内存及硬盘的占用情况等。由于我用的是Centos Stream系统，这里就以该系统为例讲解neofetch安装及使用方法，其他系统类似，安装命令就跟你安装其他软件一致。

Neofetch安装

终端输入如下命令即可开始安装neofetch

#Centos Stream系统
dnf install neofetch

Neofetch使用

使用非常简单，只需要在终端里输入neofetch即可

[root@iZwz98biiph4vhee88vxj8Z ~]# neofetch
                 ..                    root@iZwz98biiph4vhee88vxj8Z

}

控制显示选项的主要是上述代码部分，这里列出了你在运行neofetch后，终端里显示的选项。其中，#表示该行不显示，你可以删掉前面的#以让其显示。

剩下的配置文件都是一些高级订制选项，比如内存是否显示占用百分比等。
