التدقيق الأمني
مخاطر منخفضةStatic analyzer flagged 170 patterns but evaluation confirms these are FALSE POSITIVES. The skill contains legitimate bash scripting templates for system administration. Command substitution, sudo usage, and /proc access are expected patterns for educational shell scripts. No malicious intent detected. Minor warnings apply due to sudo privilege escalation patterns which should be documented for users.

ماذا يمكنك بناءه
Automated Backup System
Set up automated daily backups of critical directories with rsync to remote servers, automatic rotation to keep only recent backups, and database dumps for complete disaster recovery.
Server Health Monitoring
Deploy monitoring scripts to track CPU, disk, and memory usage with configurable alert thresholds. Generate daily health reports and receive notifications when resources exceed limits.
User Account Lifecycle Management
Automate user provisioning with account creation scripts, generate password expiry reports for compliance audits, and bulk-manage accounts across the organization.

Create a bash script to backup the /var/www directory to /backup daily, keeping only the last 7 backups. Include timestamped filenames and error handling.
Generate a monitoring script that checks CPU usage, disk space, and memory. Send an alert email to admin@example.com when any metric exceeds 85%. Log all readings to a file with timestamps.
Write a script to backup all MySQL databases, compress each dump file, upload to an S3 bucket, and delete local copies older than 14 days. Include error handling and logging.
Create a script that connects to multiple servers via SSH, collects system information (hostname, OS, CPU, memory, disk), and generates a consolidated HTML report. Include uptime and top processes for each server.
أفضل الممارسات
- Always test scripts in non-production environments before deploying to production servers
- Use absolute paths in scripts to avoid failures when executed from different directories
- Quote all variables to handle paths and values containing spaces or special characters
تجنب
- Do not hardcode passwords or API keys in scripts - use environment variables or secure secret management
- Avoid running scripts as root unless absolutely necessary - use sudo for specific commands instead
- Never skip error checking - always verify command success with proper exit code handling
