Day 2 : Basics linux command

These commands are essential for navigating, creating, manipulating, and managing files, directories, and system settings in Linux. They form the foundation of everyday tasks and operations in a Linux environment.

📂 mv - Move or rename files in Linux

📂 cp - Similar usage as mv but for copying files in Linux

📂 rm - Delete files or directories

📄 cat - Display file contents on the terminal

📄 clear - Clear the terminal display

🖥️ uname - Linux command to get basic information about the OS

👤 whoami - Get the active username

🔒 chmod - Command to change file permissions

🔌 ifconfig - Display network interfaces and IP addresses

🔒 passwd - Create or update passwords for existing users

📁 ls - The most frequently used command in Linux to list directories

📂 cd - Linux command to navigate through directories

📂 mkdir - Command used to create directories in Linux

📂 touch - Create blank/empty files

🔤 echo - Print any text that follows the command

lsb_release -a : useful for troubleshooting or when you need to know the exact version of your OS.

Checking your present working directory:

The command pwd (print working directory) provides you with the absolute path of your current location within the file system. It's like a GPS system that tells you where you are.

List All Files and Directories (Including Hidden)

To list all files and directories, including hidden ones, use the ls command with the -a option:

Here, . represents the current directory, .. represents the parent directory, and other entries are files and directories.

To create a nested directory structure A/B/C/D/E, use the mkdir command with the -p option to create parent directories if they don't exist:

Create Nested Directory Structure

This command creates a directory structure where:

• A contains B

• B contains C

• C contains D

• D contains E

After executing this command, you'll have a nested directory structure created from your current working directory.

You can check it using tree, but for that first you need to install package

Conclusion:

Mastering the Linux command line opens up a world of possibilities in managing your file system efficiently. With few basic commands we also have covered three essential commands: pwd to check your present working directory, ls -a to list all files and directories (including hidden files), and mkdir -p to create nested directories. With these tools at your disposal, you'll be well-equipped to navigate and organize your files like a pro.

So, embrace the power of the command line and embark on your Linux journey with confidence!
