## Overview

Linux System Monitor is a small Bash-based system maintenance and reporting tool. The documented workflow runs every six hours, updates essential software, monitors system performance, and emails a report to the administrator. The README does not clarify the roles of monitor.sh or the mismatch between its reference to ssmtp.sh and the present ssmtp.conf; those details are not inferred.

Main entry points: [`system_monitor.sh`](https://github.com/nabikonan/linux-system-monitor/blob/main/system_monitor.sh) (System monitor), [`system_monitor.service`](https://github.com/nabikonan/linux-system-monitor/blob/main/system_monitor.service) (Systemd service), [`ssmtp.conf`](https://github.com/nabikonan/linux-system-monitor/blob/main/ssmtp.conf) (SMTP configuration)
