Generate a Complete Linux Server Health Report with a Single Command

Today I share a hidden gem for Linux operations: a one‑line solution that instantly provides CPU, memory, disk, and IP details without manually running multiple commands like cat /proc/cpuinfo , free -h , df -h , or ip addr .

Now a single command can generate a formatted, color‑coded server health report covering all key information.

Here is the "Health Report" you need

Run the following command and obtain a structured server configuration list in about three seconds:

curl -s 'https://download.xlsys.cn/tools/Shell/system_info.sh' | bash

If you need to check a remote server, execute it via SSH:

# Remote server execution example
ssh user@host "curl -s https://download.xlsys.cn/tools/Shell/system_info.sh | bash"

Previously, assembling a configuration list required half an hour of manual commands; now the script produces a professional report in ten seconds, ready to send to customers.

  printf "%-15s : %s

 done

In Summary

This script contains no complex logic or flashy code, yet it solves a common ops pain point—fragmented information—by consolidating data from five commands into a clear report, freeing you from repetitive work.
