My Linux Journey

Hey everyone! I’m Sanjay Singh Panwar , a DevOps aspirant who just completed learning Linux basics. When I started,e I was overwhelmed with commands, file systems, and permissions. But after consistent practice, I can now navigate Linux confidently! In this blog, I’ll share my learning journey, key concepts, and tips for beginners. Let’s dive in!

In this blog, I’ll share:

• Why Linux is important for DevOps

• Key concepts I learned

• Challenges I faced & how I overcame them

• Next steps in my DevOps journey

• My Advice for Beginners

1) Why linux is important for DevOps :)

• Most servers run on Linux.

• Automating tasks with Bash scripting saves time.

• with linux we can work by command rather than manual work.

• Automation tools (Ansible, Terraform, CI/CD pipelines) work best on Linux.

2) Key concepts I learned :)

1) File and Directory Operations Commands ::

• ls - for list file and directories

• cd - for change directory

• pwd - print current working directory

• mkdir - create a new directory

• cp - copy files and directory

• mv - move/rename files and directories

2) File Permission Commands ::

• chmod - change file permissions

• chown - change file ownership

• chgrp - change group ownership

• umask - set default file permissions

3) Process Management Commands ::

• ps - display running processes

• top - Monitor system processes in real-time

• kill - Terminate a process

• pkill - Terminate processes based on their name

• pgrep - List processes based on their name

4) System Information Commands ::

• uname - Print system information

• whoami - Display current username

• df - Show disk space usage

• du - show file and directory sizes

• free - Display memory usage information

• uptime - Show system uptime

5) Networking Commands ::

3) Challenges I faced & how I overcame them :)

• Permission Denied" errors — Learned sudo, chmod, and chown

• Forgot command syntax — Used man [command] and --help

4) Next steps in my DevOps journey :)

Now that I’m comfortable with Linux, my next goals are:

• Shell Scripting (Advanced)

• Git & GitHub for Version Control

• Docker & Kubernetes

• Infrastructure as Code (Terraform/Ansible)

5) My Advice for Beginners :)

1. start with small commands

2. Break problems into chunks
