Introduction

Before you launch Kubernetes clusters or build CI/CD pipelines, you NEED these fundamental skills. File operations are the building blocks of DevOps greatness. This isn't optional, it's the secret weapon that separates pros from pretenders.

Think your GUI is faster? Think again. Terminal masters accomplish in seconds what takes GUI users minutes.

Directory Domination: Create Directories like a pro

# mkdir is used to create directory (folder).

Single Directory Creation:

# mkdir /project_team

Just like that, directory created.

Multi-Directory Magic:

# mkdir /admin /technology /operands

Three directories, one command. Efficiency unleashed!

Pattern Creation:

 # mkdir /project{1..5}

BOOM! You just generated project1 through project5 instantly.

Nested Directory Superpowers: Creating a directory inside a directory (parent/permissive)

# mkdir -p deployment/kubernetes/services/config

The -p flag is your recursive superpower. Entire directory trees spawned with a single command.

Tip: Use meaningful directory names. Future-you will thank present-you.

File Creation Mastery

Create empty Files in an instant with # touch

# touch /server

Empty file, ready for action.

Multiple File Creation

# touch /input /output /screen

Three files, one command. Well-done!

Sequential Pattern Creation

# touch /log{1..10}.txt

Just created 10 log files in less time than it takes to click "New" in a GUI.

The Cat Command: Create, Write, Read in one tool

This command allows to create, read & add Content but not edit.

Create & Write Content with # cat >

# cat > deployment.txt

(Press Ctrl+d twice to save)

Add More Content (Append Mode)

# cat >> /deployment.txt

(Press Ctrl+d twice to save)

Read File Contents

# cat < /deployment.txt

View your creation in all its glory.

Copy Files with Surgical Precision

Understanding the flags (options):
-r: recursive (for directories)
-v: verbose (shows what's being copied)
-f: force (overwrite without asking)

Basic File Copy # cp

# cp -v /log1.txt /cloud

Copy with -v (verbose) to see exactly what's happening.

Copy Entire Directories

# cp -rv /project /sbin

The -r flag recursively copies everything within the directory.

Pattern-Based Copy

# cp -rvf *.txt /etc

Copy all text files in one swift command.

Sequential Copy Operations

cp -rvf log{1..5}.txt /var

Copy multiple numbered files with a single command.

Delete with Confidence (and Caution!!!)

Delete with # rm

Single File Removal

# rm -rvf /deployment.txt

Multiple File Deletion in a Sequence

# rm -rvf /log{1..5}.txt

Directory Deletion

# rm -rvf /project_team

Pattern-Based Cleanup

# rm -rvf /log*

DANGER ZONE: Handle with extreme care

rm -rvf /* - DELETES EVERYTHING IN CURRENT DIRECTORY

NEVER run this without absolute certainty of your current directory!

Move & Rename: The Versatile MV Command

Rename a File

mv /log1.txt /pro1.txt

Simple. Powerful. Done.

Practical Challenge: Build a simple project from scratch

Let's put it all together with a simple real-world project structure:

Create the project structure

Create configuration file

Add Content to Linux file (Do not forget Ctrl+d twice)

Create deployment script

Make script executable

Copy Configurations to a backup location

List your project Structure

Congratulations: You're now a Terminal Master!

If you've made it this far, you're no longer a CLI novice. You've mastered the most essential Linux file operations that DevOps Engineers, System Administrators, and Cloud Architects use daily.
