Linux System Administration & Automation Scripts 🐧🛠️

A curated collection of production-ready Bash/Shell scripts for Linux system administration, Tier 2/3 technical support, server health monitoring, and routine task automation.

• check_disk_usage.sh: Monitors disk space usage and alerts when partition consumption exceeds safety thresholds.
• check_service_status.sh: Validates the status of critical system services (e.g., SSH, Systemd, NGINX) and attempts automatic restarts if down.

• automated_backup.sh: Generates timestamped, compressed tarball backups of essential system directories and logs cleanup routines.

• network_ping_sweep.sh: Performs basic ICMP reachability checks across subnets for network troubleshooting.

• Linux OS (Debian, Ubuntu, CentOS, RHEL, or Fedora)
• Bash shell environment (/bin/bash)
• Root or sudo privileges for administrative execution

Before running any script, grant execution permissions:

chmod +x monitoring/*.sh
chmod +x backup/*.sh
chmod +x network/*.sh
