Here are three advanced Bash scripts designed for enterprise-scale tasks, showcasing complexity, scalability, and efficiency:

1. Automated Server Deployment Script:

bash

#!/bin/bash

# Script for automated deployment of servers in an enterprise environment

# Define variables
server_count=30
base_image="/path/to/base/image.qcow2"
network_config="/path/to/network/config.yaml"

# Loop through server count and deploy each server
for ((i=1; i<=$server_count; i++))
do
    # Generate unique server name
    server_name="server$i"

    # Clone base image for server
    qemu-img create -f qcow2 -b $base_image $server_name.qcow2

    # Customize network configuration for server
    sed "s/hostname: server/hostname: $server_name/" $network_config > $server_name-config.yaml

    # Spin up server instance
    virt-install --name $server_name --ram 2048 --vcpus 2 --disk path=$server_name.qcow2 --network bridge=virbr0 --os-type linux --os-variant ubuntu20.04 --graphics none --console pty,target_type=serial --location 'http://archive.ubuntu.com/ubuntu/dists/focal/main/installer-amd64/'
done

# Display success message
echo "$server_count servers deployed successfully."

This script automates the deployment of multiple virtual servers in an enterprise environment, customizing network configurations for each server instance.

1. Automated Data Backup and Retention Script:

bash

#!/bin/bash

# Script for automated data backup and retention in an enterprise environment

# Define variables
source_dir="/path/to/source"
backup_dir="/path/to/backup"
retention_days=30

# Create backup directory if not exists
mkdir -p $backup_dir

# Backup source directory
tar -czf $backup_dir/backup_$(date +%Y-%m-%d).tar.gz $source_dir

# Remove backups older than retention period
find $backup_dir -type f -mtime +$retention_days -exec rm {} \;

# Display success message
echo "Backup completed successfully."

This script automates the backup of enterprise data, compresses it into a tarball, and removes backups older than the specified retention period.

1. Security Compliance Assessment Script:

bash

#!/bin/bash

# Script for security compliance assessment in an enterprise environment

# Define variables
audit_report="/path/to/audit/report.txt"
critical_services=("sshd" "httpd" "mysql")

# Record system information
echo "Security Compliance Assessment Report" > $audit_report
echo "Date: $(date)" >> $audit_report
echo "Hostname: $(hostname)" >> $audit_report
echo "Kernel Version: $(uname -r)" >> $audit_report
echo "Uptime: $(uptime)" >> $audit_report

# Check for open ports
echo -e "\nOpen Ports:" >> $audit_report
netstat -tuln >> $audit_report

# Check for critical services running
echo -e "\nCritical Services Status:" >> $audit_report
for service in "${critical_services[@]}"
do
    if systemctl is-active --quiet $service.service; then
        echo "$service: Running" >> $audit_report
    else
        echo "$service: Not Running" >> $audit_report
    fi
done

# Display audit report location
echo -e "\nAudit report saved to: $audit_report"

This script conducts a comprehensive security compliance assessment in an enterprise environment, checking for open ports and the status of critical services, and generates a detailed audit report.

These advanced Bash scripts demonstrate sophisticated automation capabilities for enterprise-scale tasks, enhancing productivity, reliability, and security across the organization.
