14 Most Important Linux Commands You Should Know

Linux is a free, open-source operating system released under the GNU General Public License. Its first version, which consisted of 88 files, was launched in September 1991. At that time, nobody would have imagined that it would become so popular worldwide. Linux currently occupies over 4.03 per cent of the market share globally. It runs the world’s top 500 supercomputers and is a preferred choice for accessing desktops and servers. However, the OS is useless until you don’t know the right Linux commands. 

So, learning about its commands becomes crucial. There are around 1000 commands in Linux, and remembering all of them is difficult. Also, people use only specific commands depending on their needs. Despite being a free and open-source operating system, Linux has many more advantages, which you can explore here. This blog provides details about the most useful Linux commands, so whether you are a new user or an experienced one, this write-up will be helpful to you.

1. Ls Command

Ls is the first command anyone can type and use on a Linux terminal. It helps you list the contents of the directory you need. This instruction has different options like -S, -R, -i, etc., so it is better to get some help.

2. Alias Command

Alias is a shell in-built command that converts complex instructions into simpler ones. Also, the new command will have the same functionality as the original one. Ultimately, it helps you use longer instructions easily and efficiently. 

3. Unalias Command

If you use the Alias command to simplify complex instructions, you are likely to remove it at some point. One of the Linux commands, unalias, will help you with that. It will remove the alias definition from the shell environment. 

4. Pwd Command

PWD stands for the print working directory and writes the complete pathname of the current running directory. To use this command, enter the pwd command in the Linux terminal and press the enter button.

5. Cd Command

Cd is also called chdir (change directory) and is a shell instruction. It is used to change the current working catalogue in operating systems. You can also locate specific catalogues by highlighting their paths.

6. Cp Command

Cp is a UNIX CLI tool among Linux commands used to generate copies of files and catalogues in file systems. Modern Linux distributions provide a copy feature with GUI (graphics user interface), but this method is efficient when working with multiple files. 

7. Rm Command

Rm is one of Linux's fundamental instructions. It manages files and directories. Users can delete selected files or directories by writing the file name followed by rm in the Linux terminal. 

8. Mv Command

Do you wish to move a file from one place to another in the Linux operating system? If so, Mv can help you. It is one of the most used Linux commands. You can also rename a file using this command. 

9. Mkdir Command

Mkdir stands for “make directory”, and as the name suggests, it enables you to create new directories (more than one at a time) in the Linux system. You can specify the permissions of new directories with the -m Mode flag.

10. Man Command

Do you wish to see the user manual for commands you can run on a Linux terminal? The man command can help you with this task. It will give you a detailed view of commands, including name, synopsis, description, options, etc.

11. Grep

Grep is a short form of global regular expression print, which is an instruction to find and match text patterns in files. This command is helpful for developers who are searching for certain occurrences in the code file.

12. History Command

The history, among Linux commands, allows you to see the recently entered commands in the system. You can execute a specific command once all the instructions are shown.

13. Head Command

The head command writes the stated number of lines or bytes from files. If you use this command without any flag, the head instruction displays ten lines of the specified file.

14. Find Command

Find is one of the most used commands in Linux and helps you locate files and directories. It’s versatile, and you can search by name, size, type, and other criteria. 

Most Useful Linux Command

Linux has around 1000 commands open, but not all of them are regularly used. Find, history, cd, cp, mv, grep, etc. are some commands that are mostly used in daily life. So, learn them and use the Linux system efficiently. We hope you like this blog about Linux commands.
