Linux provides a set of powerful and commonly used commands to interact with the system efficiently. The cd command is used to change directories, while ls lists the contents of a directory. To clear the terminal screen, the clear command is used. The mkdir command helps create new folders, and pwd shows the current working directory. The rm command is used to remove files or directories, and touch is used to create empty files. To edit or view text files directly in the terminal, vi is a powerful editor. The / symbol represents the root directory, which is the top level of the Linux filesystem. To manage users, adduser is used to create a new user, and userdel is used to delete an existing one. The history command displays a list of previously executed commands, allowing users to track or reuse them easily. These commands form the foundation for working effectively in a Linux environment.
5. mkdir
mkdir Command in Linux
mkdir stands for "make directory".
It is used to create a new folder (directory) in the Linux file system.
🔹 Basic Syntax:
mkdir [directory_name]
🔹 Examples:
✅ 1. Create a single directory
mkdir myfolder
👉 Creates a folder named myfolder in the current directory.
✅ 2. Create multiple directories at once
mkdir folder1 folder2 folder3
👉 Creates three folders in the current location.
✅ 3. Create nested directories (with -p option)
mkdir -p projects/linux/scripts
👉 Creates the full path, including parent folders if they don’t exist.
🔹 Verify the creation:
Use ls to list and confirm:
ls
🔹 Example in Practice:
cd ~mkdir practicecd practicemkdir -plinux/directory1ls -R
👉 This creates a structure like:
practice/└──linux/└──directory1/
