System Health Check Script

MediumShell Scripting20-30 min

The brief

Write a system health-check script at /root/case/healthcheck.sh that an operator can run to get a quick status report of the box. It must report three things: disk usage, memory usage, and system load. Make the script executable and make sure it runs cleanly (exits 0). Grading runs your script: it must be executable, succeed, and actually run the disk (df), memory (free), and load (uptime) queries, not just mention them.

What you'll do

Create an executable script at /root/case/healthcheck.sh
Report disk, memory, and load
Exit cleanly (status 0)

Hands-on lab: you work on a real Linux box in your browser, graded on the machine's actual state.
