25 Basic Linux Commands For Beginners

“Master essential Linux commands for beginners with our concise guide. Streamline your operations in the Linux terminal effortlessly.”

While performing a task, we all need shortcuts. Shortcuts help us to complete a task quickly. Linux comes with such commands which are one to two words, using that commands, you can perform several operations in no time. As a beginner, you must be aware of those basic Linux commands to complete an operation in a short time in the Linux-based operating system.

In this article, you’ll be going through some of the basic Linux commands which beginners can use to complete their tasks very quickly. Let’s go through each, but before that have a short idea on Linux.

What is Linux?

Linux is a free and open-source software that operates on its own operating system. The term ‘Linux’ stands for GNU + Linux. Initially developed by Linus Torvalds, it was created alongside the source code of Unix. While Linux is extensively utilized for various purposes, its applications are well-known to many.

Use of Linux Commands

Linux commands is a type of Unix command or shell procedure. They are the basic tools used to interact with Linux on an individual level. Linux commands are used to perform a variety of tasks, including displaying information about files and directories.

Linux operating system is used on servers, desktops, and maybe even your smartphone. It has a lot of command line tools that can be used for virtually everything on the system.

All users should be familiar with most of these commands as they are required for most operating system tasks and computer programming.

Here we have put all the Basic Linux Commands that every Linux user (as a beginner) should know. These are not all you should know, but these are the basic and most commonly used commands.

25 Most-Commonly Used Linux Commands

1. Is command in Linux

The ls command is commonly used to identify the files and directories in the working directory. This command is one of the many often-used Linux commands that you should know.

This command can be used by itself without any arguments and it will provide us the output with all the details about the files and the directories in the current working directory. There is a lot of flexibility offered by this command in terms of displaying data in the output. Check the below image for the output.

ls command in linux

2. pwd command in Linux

The pwd command is mostly used to print the current working directory on your terminal. It is also one of the most commonly used commands. 

Now, your terminal prompt should usually include the entire directory. If it doesn’t, this is a quick command to see which directory you’re in. Another purpose for this command is when creating scripts because it can help us find the directory in which the script was saved. The below pictures are the output with the command.

Command:
 

pwd command in linux

Output:

output of pwd command in linux

3. mkdir command in Linux

This mkdir command allows you to create fresh directories in the terminal itself. The default syntax is mkdir <directory name> and the new directory will be created.

For example, if you want to create a directory as “GeeksforGeeks” then the basic syntax would be:

mkdir GeeksforGeeks

In case you want to create another directory inside the main directory GeeksforGeeks to store projects, you can use the following command to do so. mkdir GeeksforGeeks/projects

Command:

mkdir command in linux

Output:

output of mkdir command in linux

You can see we used ls first to see the directories present there and then mkdir to create another directory followed by ls to view the created directories.

4. cd command in Linux

The cd command is used to navigate between directories. It requires either the full path or the directory name, depending on your current working directory. If you run this command without any options, it will take you to your home folder. Keep in mind that it can only be executed by users with sudo privileges.

Command:
 

cd command in linux

Output:

output of cd command in linux

Here we used pwd to view the current directory for reference and then we used cd GeeksforGeeks to switch the directory and with again pwd command we can see the output is the switched directory, i.e – GeeksforGeeks

5. rmdir command in Linux

The rmdir command is used to delete permanently an empty directory. To perform this command the user running this command must be having sudo privileges in the parent directory. 

Command:
 

rmdir command in linux

Command to remove the directory

Output:

output of rmdir command in linux

Here we used the ls command to check the directories present there and used rmdir <directory name> to delete the directory and again the ls command to view the directories after deleting the same.

6. cp command in Linux

The cp command of Linux is equivalent to copy-paste and cut-paste in Windows. 

Command:

cp command in linux

Output:

output of cp command in linux

Here we used ls to view the files and then used cp to copy the files of first.txt to second.txt and again used ls command to view the updated files.

7. mv command in Linux

The mv command is generally used for renaming the files in Linux.

Command:

mv command in linux

Output: 

output of mv command in linux

Here we used the ls command to check the directories and then used mv <file name> <Renamed file name> to rename the files, and then again we used the ls command to view the renamed file as you can see in the output screenshot.

8. rm command in Linux

rm command in Linux is generally used to delete the files created in the directory. 

Command:

rm command in linux

Output:

output of rm command in linux

You can see as we wrote the ls command to view the files in the terminal and then rm <file name> to delete the files and again we had the ls command to check the update.

9. uname command in Linux

The uname command is used to check the complete OS information of the system. Check out the command and the output below

Command: 

uname command in linux

Output:

output of uname command in linux

10. locate command in Linux

The locate command is generally used to locate the files in the database. Use an asterisk (*) to search for content that contains two or more words. As an example: locate first*file. This command will search the database for the files that contain these two names first and file.

Command: 

locate command in linux

Output:

output of locate command in linux

We first used the rm command to delete the file and then used the locate command to find the file in the database which in return has given the output with a -e as the file was removed.

11. touch command in Linux

The touch command creates an empty file when put in the terminal in this format as touch <file name> 

Command: 

touch command in linux

Output: 

output of touch command in linux

We used the ls command to check the current directories in the terminal and then used the touch command to create an empty file and then again we used ls to find out the created file in the terminal.

Here we used mkdir to create two directories and then we used ln with an -s to create a soft link in it.

13. cat command in Linux

The cat command is the simplest command to use when you want to see the contents of a particular file. The only issue is that it simply unloads the entire file to your terminal. If you want to navigate around a huge file, should use less command alternatively.

Command:

cat command in linux

Output:

output of cat command in linux

output of man command in linux

17. grep command in Linux

The grep command is used to find a specific string in a series of outputs. For example, if you want to find a string in a file, you can use the syntax: <Any command with output> | grep “<string to find> “

For Example:

cat Files.txt | grep “new”

Command: 

grep command in linux

Output: 

output of grep command in linux

In this command, we first used cat <file name> to view the content of the file, and then we used cat <file name> | grep “string” to check the string in it.

18. echo command in Linux

echo command in Linux is specially used to print something in the terminal

Command:
