Linux Process Management & Troubleshooting Simulator

A structured 10-step Linux incident response framework covering diagnostics, remediation, and verification. Walks through a production incident scenario using commands like df, du, ps, kill, free, top, systemctl, journalctl, chmod, and chown. Includes a kill signal escalation guide (SIGTERM → SIGKILL) and a clear explanation of the difference between chmod (permissions) and chown (ownership), with a common root-ownership gotcha.
