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 are 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 Basic Linux Commands that every Linux user (as a beginner) should know. These are not all that 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.
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:
Output:
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 “neveropen” then the basic syntax would be:
mkdir neveropen
In case you want to create another directory inside the main directory neveropen to store projects, you can use the following command to do so. mkdir neveropen/projects
Command:
Output:
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:
Output:
Here we used pwd to view the current directory for reference and then we used cd neveropen to switch the directory and with again pwd command we can see the output is the switched directory, i.e – neveropen
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:
Command to remove the directory
Output:
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:
Output:
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:
Output:
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:
Output:
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.
