LINUX is an operating system or a kernel distributed under an open-source license. Its functionality list is quite like UNIX. The kernel is a program at the heart of the Linux operating system that takes care of fundamental stuff, like letting hardware communicate with software.
Why do you need an OS? Linux vs Unix, windows vs Linux and brief concept of Linux.
Linux provides a powerful command-line interface compared to other operating systems such as Windows and MacOS. We can do basic work and advanced work through its terminal. We can do some basic tasks such as creating a file, deleting a file, moving a file, and more. In addition, we can also perform advanced tasks such as administrative tasks (including package installation, user management), networking tasks (ssh connection), security tasks, and many more.
Access to Linux system. Details about file management in Unix. All data in Unix is organized into files. All files are organized into directories. These directories are organized into a tree-like structure called the filesystem.
All the files, whether ordinary, special, or directory, are contained in directories. Unix uses a hierarchical structure for organizing files and directories. This structure is often referred to as a directory tree.
we will discuss the services available in the Linux operating system. We will explore many services including web servers and database servers, among others. We will look at how you start and stop services from running in the Linux operating systems.
A Mock Test on the fundamentals
In this session, we will discuss in detail about Printing and Email as the basic utilities of Unix.
You can connect two commands together so that the output from one program becomes the input of the next program. Two or more commands connected in this way form a pipe.
Configure networking and hostname resolution statically or dynamically.
A Linux System Administrator manages the operations such as maintaining proper software, observing them, and even taking care of backup and hardware systems.
A shell script is a computer program designed to be run by the Unix/Linux shell which could be one of the following:
The Bourne Shell
The C Shell
The Korn Shell
The GNU Bourne-Again Shell
A shell is a command-line interpreter and typical operations performed by shell scripts include file manipulation, program execution, and printing text.
A Mock Test on the Networking Concepts, Administration and Shell Scripts
The number of Linux text editors has been steadily rising over the past two decades. All Linux distributions come with a built-in text editor. But some editors add extra features or an easy-to-use interface.
Maintaining a system's network is a task of System/Network administrator. Their task includes network configuration and troubleshooting. System Updates and Repos in Linux:
In this you will List, create, delete, and modify physical storage partitions. A run level is a state of init and the whole system that defines what system services are operating. Run levels are identified by numbers.
Most advanced Linux distributions give users the opportunity to dig deep into their computer to find out exactly what’s happening underneath the hood, and they provide a great way to learn a lot more about how computers work.
Signals are software interrupts sent to a program to indicate that an important event has occurred. The events can vary from user requests to illegal memory access errors. Some signals, such as the interrupt signal, indicate that a user has asked the program to do something that is not in the usual flow of control.
