What is Linux system administration?

Linux is an operating system or kernel created by Linus Torvalds with other contributors. First started on 17 September 1991. The main advantage of Linux is that it is an open-source license. It means that programmers can use the Linux kernel to design their own custom operating systems. Most of the Linux code written in the C programming language.

Some of the most popular operating systems that use Linux as a kernel are Debian, Knoppix, Ubuntu, and Fedora. However, the list does not end here, as there are thousands of Linux-based operating systems that provide users with a variety of functions.

Introduction to Linux system administration: Linux is a significant strength in computer technology. Most web servers, cell phones, personal computers, supercomputers, and cloud servers use Linux. The job of a Linux system administrator is to manage the operations of a computer system. These include maintenance, enhancements, user accounts/reports, Linux tool backups, and command-line interface tools. Most computing devices work with Linux because of its high stability, high security, and open-source environment. There are a few things a Linux system administrator should know and understand:

·         Linux file systems
·         File system hierarchy
·         Root/superuser administration
·         Basic bash command
·         Management of files, directories, and users

·         Run tests on each new software, manage administration service patches, and perform audits on all security processes.

In summary, the main task of the Linux system administrator is to manage operations such as installation, monitoring of software and hardware systems and backups. And it also has an excellent ability to describe a deep understanding of technical knowledge. Even first-year professionals have a unique opportunity to assume the position of systems administrator since the average annual salary is 3 INR and the salary increases with the increase in work experience.
