Essential Shell Commands

Focus Area: Command Line Fluency


🎯 Context & Objective

Getting really comfortable with the shell commands I’ll use constantly in DevOps work. Building a reference guide I can come back to whenever I need it.

âś… Work Recap & Achievements

Command Documentation: Put together a guide covering 60 important bash commands with examples focused on DevOps scenarios.

Practice Time: Actually spent time using these commands instead of just reading about them. Working on building muscle memory for the ones I’ll need most.

Real-World Context: Connected each command to actual DevOps tasks—log analysis, process monitoring, file manipulation, system checks.

What I made:

  • 60 Greatest Bash Commands - my reference guide
  • Practice notes with useful command combinations
  • Better typing speed for common commands

đź§— Challenges & Struggles

Too Much Info: With so many flags and options, it’s easy to try learning everything at once. Had to focus on what’s actually useful first.

Different Distros: Some commands work differently depending on the Linux distribution. Had to look up compatibility issues.

📚 Key Learnings & Progress

What I learned:

  • Text processing with sed, awk, and grep for analyzing logs
  • Process management using ps, top, htop, and kill
  • File system navigation with find, locate, and ls
  • Network troubleshooting with netstat, ss, and lsof

Key Takeaway: Time spent getting fast with the command line now saves a lot of headache later when managing multiple servers and containers.

⏭️ Next Steps & Closing Thoughts

This was good, focused practice. Command-line speed matters more than people think—it’s one of those things that shows experience.

Writing the documentation helped me learn. Explaining what each command does made it stick better.

Next: setting up my Mac with all the DevOps tools—Docker, Kubernetes, cloud CLIs, etc. Better to get everything configured now than deal with installation issues while trying to learn. 🛠️
