Script written by shell to detect hardware information in linux

I previously wrote a script for detecting windonws hardware information in python. Here is a linux system hardware information detection script written using shell a long time ago. You can check it against it. The detection content is basically the same: operating system information, memory, CPU, hard disk partition and mounting, Nic configuration, installed software information, etc.

#This script is used to check the server
