Bash is a UNIX shell-compatible command process whose main task is to manipulate strings conducted in a shell environment. Programmers are at times called upon to work on different files. They can add, delete, and replace parts or the whole file to fit their work. This calls upon the knowledge of replacing string in bash.

A zombie process in Linux refers to those already dead processes but, in one way or another, are still present in the process table of the system. The loophole is that, for some reason, this process was not cleaned by the parent from the process table. Usually, this happens after the completion of the execution process.

Previously, we have written articles on various Linux commands like ls, ps, scp, history, and many more present on our website. Today, we will take a look at the WC command. WC stands for “Word Count.” And as the name implies, the wc command is used for counting purposes.

Any programmer knows how vital variables are. Variables act as way-stations for coders/programmers where they pass information back and forth. Variables are generally crucial in computing since they enable code to be dynamic. In other terms, variables are referred to as information placeholders that change repeatedly depending on their usage. However, a significant problem that has affected most coders and programmers is keeping track of many variables in a project.

The Linux Operating System provides several ways of terminating a Linux operating system process. The obvious way to stop a program is by clicking the X button in the top left or right corner. But there are myriad other ways to kill any process; we are here to discuss those.

Sometimes you might need to search a particular word or a string inside a file. To do this, almost every text editor has some sort of GUI implementation to help you out. But for Linux users, it is much more productive and convenient to do these searches from the command-line.

In any system environment and domain, the security of data and services accommodated by this system deserves the topmost priority. Properly securing an OS or other systems whose security depends on a generated password is essential. This makes the usage of a secure password an important footprint for all users. The passwords you use on your systems help secure your data and user activities from unauthenticated intruders. How you create these passwords needs to be unpredictable.

The world of Linux is uniquely structured by its maze of commands that continue to make it more than just an ordinary operating system. A typical Linux desktop user might relate to several hundreds of these commands. On the other hand, a server administrator used to bare-bone Linux server’s packages installation and management can count over 1000 differing commands.

We cannot 100% declare ourselves as complete Linux users or enthusiasts without having boarded the same train with the famed official Linux Mascot, Tux Penguin. There is more to why Linux chose Tux Penguin as its brand ambassador other than the fact that a Penguin has a big head and can adapt to the survival of inhumanely cold weather. We can relate the size of its head to the numerous adaptive commands they share with the Linux operating system.

The Linux OS and its related distros and flavors have transformed it from hardcore software into an industrial brand. Even if you are not a fan of it, the Linux OS might be as common as the air you breathe if you closely analyze your day to day interactive activities. Almost all the modern technologies that transform and innovate the tech industry have a Linux OS DNA imprinted on them.
