Introduction

Linux, with its robustness, flexibility, and open-source nature, has become a popular operating system for both personal and professional use.

If you're new to Linux, understanding some basic Linux commands will lay a solid foundation for navigating the command line interface efficiently.

These commands are carefully selected to introduce newcomers to fundamental concepts and functionality. While this list may not include all possible commands, it does provide beginners with an adequate starting point to learn and navigate the Linux command line.

Let us get started!

Essential Linux Commands For Beginners

1. ls - Listing Files and Directories:

The "ls" command is used to list files and directories in the current working directory. By default, it displays the names of files and directories in a simple list format. Adding options such as "-l" (long format) or "-a" (including hidden files) can provide more detailed information or reveal hidden files respectively.

Example:

$ ls
directory1  file1.txt  file2.txt

2. cd - Changing Directories:

The "cd" command allows you to change directories and navigate through the Linux file system. Use it followed by the directory name or path to move to a specific location. Typing "cd" alone takes you to your home directory.

Example:

$ cd directory1

3. pwd - Present Working Directory:

To know the current working directory, use the "pwd" command. It displays the absolute path of the directory you are currently in.

Example:

$ pwd
/home/ostechnix/directory1

4. mkdir - Creating Directories:

When you need to create a new directory, use the "mkdir" command. Specify the desired directory name as an argument, and Linux will create the directory within the current working directory.

Example:

$ mkdir directory2

5. rm - Removing Files and Directories:

To delete files and directories, use the "rm" command. Be cautious as it permanently deletes files and directories without confirmation. To remove directories, use the "-r" (recursive) option.

Example:

$ rm file.txt
$ rm -r directory

6. cp - Copying Files and Directories:

The "cp" command allows you to copy files and directories. Specify the source file/directory and the destination where you want to create a copy. Use the "-r" option for recursive copying of directories.

Example:

$ cp file1.txt directory1/
$ cp -r directory1/ directory2/

7. mv - Moving and Renaming Files and Directories:

The "mv" command is used for both moving files/directories to a different location and renaming them. Specify the source and destination names to move or rename.

Example:

$ mv file1.txt directory2/
$ mv file2.txt file2_02.txt

8. cat - Displaying File Contents:

The "cat" command allows you to display the contents of a file on the terminal. It is useful for viewing small files or combining multiple files.

Example:

$ cat file.txt

9. grep - Searching Text within Files:

The "grep" command is used to search for specific patterns or text within files. It provides powerful pattern-matching capabilities and can be combined with other commands to filter and manipulate data.

Example:

$ grep "keyword" file.txt

10. tar - Archive and Compress Files:

The "tar" command creates compressed archives of files and directories.

Example:

$ tar -czvf archive.tar.gz directory/

11. find - Search for Files and Directories:

The "find" command searches for files and directories based on specified criteria. It allows you to locate files by specifying search conditions such as filename, size, type, modified time, and more.

Example:

$ find /path/to/search -name "*.txt"

12. df - Display Disk Space Usage:

The "df" command shows the amount of available and used disk space on file systems. It provides information about the total disk space, used space, available space, and file system type for each mounted partition or file system.

Example:

$ df -h

13. du - Estimate File and Directory Sizes:

The "du" command is used to estimate and display the disk space usage of files and directories. It calculates the cumulative size of files and directories and provides a summary of the disk space they occupy.

Example:

$ du -sh directory/

The "history" command in Linux displays a list of previously executed commands by the current user in the terminal session. It provides a chronological record of the commands you have entered, along with their command numbers.

Example:

$ history
