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. Linux system administrator job 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
Duties of a Linux administrator: System administration has become a fixed requirement for a company and an institution that needs a reliable IT base. Therefore, the need for efficient Linux administrators is the required time. The job profile may change from one organisation to another as responsibilities and tasks are added to the function. Below are the few responsibilities of a Linux administrator role:
Responsibilities and duties of the Linux system administrator

- Make a complete system backup and help restore all operations and educate users
- Design and maintain all system tools for all automation processes and scripts and monitor all capacity planning.
- Integrate all necessary software and solve all problems in different technologies. The design requires commercial servers and provides backup support
- Evaluate all documents according to system requirements
- evaluate the overall design and run tests on all development activities and manage all problematic methods.
- Develop an infrastructure that meets all business needs and regularly fix system problems.
- Monitor day-to-day systems and assess the availability of all server resources and perform all activities for Linux servers.
- It helps to configure and deploy all virtual machines and to install and deploy backup copies of all configuration processes.

- Maintain and monitor all system frames, provide support after accessing all systems, and get the best Linux knowledge.
- Fix bugs in all tools, maintain multiple servers, and back up all file and script management servers.
- 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.
