Linux Commands for Developers – Introducing

Linux commands for developers are one of the most popular working systems for servers, mobile phones, supercomputers, and personal machines. The fact that it is open-source and completely free makes it separate from other operating systems. What started as a hobby by a college student soon became a revolution in the world of information technology.

You might already know this about the Android operating system based on the Linux kernel. It is estimated that more than 130 million users in the United States alone use Android smartphones. Linux is also utilized by 100 percent of the world’s supercomputers, including NASA clusters.

This makes Linux one of the most critical OS ever created. Over the past few years, I have been using Linux machines in my organization to deploy my applications on on-premises servers and Cloud machines. Knowing a few of these useful Linux commands off the top of my head has made my life a lot simpler.

Linux Commands currently, Linux is one of the most accessible operating systems, although many people are unaware of it. Thus, although Windows has a more significant presence on computers worldwide, more and more users are opting for Linux, mainly in the community of programmers. The reasons: are its reliability and security. If you are an inventor and interested in this system, don’t miss this selection of handy Linux commands to make your day-to-day life more manageable.

What is Linux?

Linux is an operating system or kernel created by a brilliant computer science student, Linus Torvalds. Working on the UNIX operating system (proprietary software), he realized that it needed improvement, so he thought of creating a system that would be receptive to changes and modifications from other users. Linux was born, a free, open-source operating system released in 1991, whose list of functions is quite similar to UNIX. It is also multi-user, multi-tasking, and multi-platform. It has a line parallel to Windows and can be used through commands.

Thousands of programmers began working to improve Linux, allowing the operating system to multiply. Being accessible and executable on PC platforms, many of its users are developers. If you want to start using Linux or manage yourself more quickly in this operating system.


Essential Linux Commands for Developers


One of the first commands you should know in Linux is. We can see the use of all Linux commands, showing a view with information such as name, synopsis, description, options, exit status, return values, errors, files, versions, examples, etc. For example, if you want to know the “cd” command and its options, you have to run the knowledge to understand its description and usage. Inman cd

Command touch

This command is used to create any new file type on Linux systems. It is beneficial for developers to allow files to be made on the server. Also, it is used to change the time of access and modification of files. Catt is one of the most used in Linux. The name of the command cat comes from ” concatenate “, its functionality is to attach files or join and add. It can read, link files, combine files, and write file contents to standard output.

Also used to display the content of a file, copy content from one file to another, display the line number, or display $ at the end of the line. Type cat followed by the file name and its extension to run this command. For example, cat archivo.txt Another of the most useful commands in Linux is the change directory o command. With the help of this command, we can browse all our directories on our system.

The options that it allows us would be:

  • Change from the current directory to a new directory
  • Change the directory using an absolute path
  • Change the directory using the relative path
  • Change to the home directory
  • Change to the previous directory
  • Change to the home directory
  • Change to the root directory
  • Change to another user’s home directory
  • Change to the directory with spaces
  • Change up to multiple subdirectories

This command lists the contents of the desired directory, files, and other nested directories. When used with no options or arguments, ls returns an alphabetical list of the names of all files in the current working directory. If you want to see the contents of other directories, type ls and then give the directory path.

You can use these variations with the ls command :

  • List all files in subdirectories
  • List hidden files
  • Show files and directories with detailed information such as permissions, size, owner, etc.

The stream editor is a powerful bulk search and replaces commands, but it’s also a legitimate text editor. This command is used to create and extract archive files. The “-cf” and ” flags create and extract archives. The command is used to locate the path of the working directory you are in. For example, if my username is “Miriam” and I am in my Documents directory, the absolute way would be: /home/Miriam/Documents.

This command allows users to create directories (folders). It enables the creation of several guides at the same time, as well as setting the permissions for the directories.

You can use these variations with the ls command :

Command find

You can use the command to search the files to search for files and directories based on their permissions, type, date, ownership, size, etc. It can also be combined with other tools like grep or sed. The command diff helps us compare two files line by line and show their difference. This command-line utility lists the changes you must apply to make duplicate files.

Command chown

shown allows you to change the owner of the file or directory. It can also change the group ownership for the file or directory. Unique helps us detect the adjacent duplicate lines and remove the duplicate lines. The unit filters continuous matching lines from the input file (which is required as an argument) and writes the filtered data to the output file.

 Command Top

The command top displays a view of running processes in Linux in real time and shows tasks managed by the kernel. Also, it offers a summary of system information to see resource utilization, memory, and CPU usage.

It displays the amount in percentage and KB of free disk space available on Linux. Command kill. This is used to close a process that does not end by helping to terminate it manually. It works by sending a signal that removes or kills a particular function or group. pings one of the most used commands that help us troubleshoot, test, and diagnose network connectivity issues. This command has more options, including checking if a host is reachable, if a server is up, your internet connection, and possible network delays.

The command allows users to know the shared object dependencies of an executable file or the shared library of an executable. add The command, short for ” list of open files .”, lists information about open files by processes running on the system. Allows you to disassemble object files or executable files. It also helps you get additional information that a binary file may contain in a readable format.

Command shutdown

This command safely stops the system. When it shutdowns, all logged-in users and processes are notified that the system is going down, and no further logins are allowed. It gives you the option to shut down the system immediately or at a specific time.

Linux The Most Important OS Ever Created

Linux has become an essential component of both the software industry and your daily life. It has become the most significant operating system ever built, powering everything from smartwatches to IoT devices, smartphones to Tesla cars as Tesla utilizes Linux Ubuntu as their operating system.

Linus Torvalds is being paid $1.5 million per year by The Linux Foundation for his contributions. Torvalds currently works from his home where he spends most of his time.

Linux has changed everything as we know technology. This is what happens when a project is open-sourced for the world to contribute and innovate. I hope we get to see many more successful open-source projects in the future.

Basic Linux Commands For Web Developers

Linux distributions support various GUIs (graphical user interfaces) but the old command-line interface (bash) still proves to be easier and quicker in some situations. Bash and other Linux shells require you to type in commands to complete your tasks and thus get named the command line interface.

Commands are directives for the computer to carry out a task. You can use commands to shut down your computer, show a list of files in the current directory or the contents of a text file, or show a message on the screen. They’re easy and powerful at the same time. If you are new to this and have always wanted to try it out, we’ve compiled a list of various basic Linux commands that you can learn and use for various tasks in several Linux distros. The list is not exhaustive but it should make for a good start for beginners or intermediate Linux users or administrators.


For example, you belong to the world of software development and you like to work with Linux sooner rather than later. In that case, you will start looking for information about its commands since it is a direct way to improve your productivity.

They are not all that is, but they are all that is. Although we have compiled some of the most important here, there are more useful Linux commands. Therefore, if you miss any or know any interesting, share it with us on our social networks.
