Introduction
Welcome back to my DevOps learning journey! Today, we're diving deeper into essential Linux commands that will skyrocket our efficiency and automation skills, particularly in file operations. These commands are fundamental to DevOps success, enabling us to streamline workflows and enhance productivity. Join me as we explore these powerful Linux commands and unlock their potential in file management!
View File Contents 📄
The cat command displays the contents of a file, allowing us to see the text or data stored within.
Change Access Permissions 🔒
The chmod command modifies the access permissions of files, controlling who can read, write, or execute them.
Check Command History ⏰
The history command shows a list of previously executed commands, giving us a recap of our command-line journey.
Remove a Directory/Folder 🗑️
The rmdir command deletes a directory or folder, allowing us to remove unnecessary file structures.
Create and View File Content 📝
The touch command creates a file and the cat command displays its contents, enabling efficient file creation and viewing.
Add Content to "devops.txt" 📝
The echo command adds content to the devops.txt file, allowing us to append data line by line.
Show Top Three Fruits from the File 🔝
Description: The head command displays the top three fruits from the "devops.txt" file, helping us extract specific lines from the file.
Show Bottom Three Fruits from the File🔻
Description: The tail command reveals the bottom three fruits from the "devops.txt" file, extracting the desired lines from the file's end.
Create and View Content in "Colors.txt" 📂
Similar to "fruits.txt," the touch command creates a "Colors.txt" file, and the cat command displays its contents, facilitating efficient file creation and viewing.
touch Colors.txt
cat Colors.txt

The echo command adds various colors to the "Colors.txt" file, allowing us to append data line by line.
echo -e "Red\nPink\nWhite\nBlack\nBlue\nOrange\nPurple\nGrey" > Colors.txt
Find Differences Between "fruits.txt" and "Colors.txt" Files 🔄
The diff command compares the contents of the "fruits.txt" and "Colors.txt" files, highlighting any differences between the two.
Thats it!
