Most Important Linux Commands You Need To Know

The Linux command line is a powerful tool with a wide range of functions. Users mostly use it to interact with their computers, and it gives them access to a variety of tools that can expedite and streamline their work. To fully utilise this capacity, you must be familiar with a few fundamental commands and shortcuts. Furthermore, grasping the fundamental commands of Linux is essential to making the most of all of its features.

I recently posed the question, “What is your favourite Linux command?” on X (previously Twitter). and I received a lot of responses.

What is your favourite Linux Command ?

After viewing most of the comments, I’ve selected a couple that might be significant which is also important to know

rm Command:

rm removes all the files from the current directory with a prompt. rm -RF removes all the files and directories recursively without a prompt

Example: rm test.txt

touch Command:

An empty file is created in the current directory by the touch command.

Example: touch test.txt

rmdir Command:

The rmdir command deletes an empty directory from the current working directory
Example: rmdir example_directory

cd Command:

It’s used to navigate between directories or folders within a file system.To go directly to the root directory we use cd command alone.

Example: cd /home/user

ls Command:

This command is used to list files and directories in a directory. When used with the -lrh options, it provides a detailed list with specific formatting

-l: Produces a long listing format, showing additional information such as permissions, owner, group, size, and modification time.-r: Lists files and directories in reverse order.-h: Prints sizes in a human-readable format (e.g., kilobytes, megabytes, gigabytes).

Example: ls -lrh

To access the manual pages for a specific command, use the man command. It offers comprehensive details on the syntax, options, and operation of a command.

Example: man ls

sudo Command:

In Unix-like operating systems, the sudo command represents “superuser do.” As determined by the security policy set up on the system, it permits a permitted user to run a command as the superuser (root) or as any other user.

Example: sudo nano /etc/hosts

Apart from these commands, there are a few more commands that you might not be aware of, so check out this video for further insights.
