Bash & PowerShell

Bash & PowerShell Mastery Roadmap

This detailed roadmap will take you from beginner to expert in Bash & PowerShell, covering scripting, automation, system administration, security, networking, penetration testing, and real-world projects.

Phase 1: Fundamentals of Bash & PowerShell

✅ Understanding Shell Scripting

  • What is a Shell? (bash, sh, zsh, PowerShell)

  • Differences Between Bash & PowerShell

  • Running Shell Scripts (.sh, .ps1 execution)

  • File Permissions (chmod +x script.sh, Set-ExecutionPolicy)

✅ Basic Commands & Scripting Bash:

  • File & Directory Commands (ls, cd, mkdir, rm, cp, mv)

  • Text Processing (cat, echo, grep, awk, sed)

  • Variables ($VAR, export VAR)

  • Loops (for, while, until)

  • Conditionals (if, case)

PowerShell:

  • Cmdlets (Get-ChildItem, Set-Location, Remove-Item)

  • Variables ($var = "Hello")

  • Loops (ForEach, While, Do Until)

  • Conditionals (If-Else, Switch)

📌 Mini Projects:

  • Bash: Automate Log Cleanup Script

  • PowerShell: System Info Report Script

Phase 2: Advanced Scripting & Automation

✅ File & Process Management

  • Process Handling (ps, kill, top, Task Manager)

  • Automating User & System Tasks (cron, schtasks)

  • Handling Logs & Errors (syslog, Event Viewer)

✅ Networking & Security Automation Bash:

  • Network Scanning (nmap, netstat, ip route)

  • SSH Automation (ssh-keygen, scp, rsync)

  • Firewall & Security Hardening (iptables, ufw)

PowerShell:

  • Managing Network Adapters (Get-NetAdapter, Test-NetConnection)

  • Automating Windows Defender (Get-MpThreat, Start-MpScan)

  • Running Remote Commands (Invoke-Command)

📌 Mini Projects:

  • Bash: Auto SSH Backup Script

  • PowerShell: Windows Firewall Rule Manager

Phase 3: System Administration & Penetration Testing

✅ System & User Management Bash:

  • User Creation & Permission Management (useradd, chown, chmod)

  • System Monitoring (htop, df -h, du -sh)

PowerShell:

  • Active Directory Management (Get-ADUser, New-ADUser)

  • Windows Event Log Analysis (Get-EventLog)

✅ Ethical Hacking & Pentesting Automation

  • Automating Recon (whois, dig, nslookup, traceroute)

  • Brute Force Automation (hydra, John the Ripper)

  • Automating Metasploit & Exploit Scripts

📌 Mini Projects:

  • Bash: Automated Reconnaissance Toolkit

  • PowerShell: Windows Penetration Testing Toolkit

Phase 4: Real-World Use Cases & Deployment

✅ Enterprise Automation & CI/CD

  • Writing Bash Scripts for CI/CD (Jenkins, GitHub Actions)

  • PowerShell for Windows Server Automation (Azure, AWS)

✅ Hardening & Security

  • Secure Shell Scripting Best Practices (set -e, trap)

  • PowerShell Execution Policy & Security (Set-ExecutionPolicy Restricted)

📌 Final Projects:

  • Bash: Automated Backup & Recovery System

  • PowerShell: Enterprise Windows Server Automation

Final Step: Real-World Practice & Skill Testing
