Linux terminal commands. Part 1

Terminal commands in Linux are commands that can be entered into the command line interface to interact with the Linux operating system. They allow the user to perform various operations, such as moving through the file system, creating and deleting files and folders, managing processes, configuring the network and much more.

What are the commands in the terminal for?

Commands in the terminal are designed to interact with the operating system and perform various tasks. They allow the user to perform the following actions:

1. File system management: allows you to navigate through the file system, create and delete files and directories, change their access rights, copy and move files.
2. Process Startup and Management: Allows you to start and terminate processes, check their status, suspend and resume their execution.
3. Working with the network: make it possible to check the availability of nodes in the network, configure network interfaces, establish a secure connection with remote servers and perform other network operations.
4. User and access rights management: you can create and delete users and groups, change their parameters and access rights, manage passwords.
5. System administration: allows you to perform various administrative tasks, such as installing and updating programs, configuring hardware, monitoring the system.
6. Task Automation: Can be used in scripts and command files to automate tasks and create automatic procedures.

Commands in the terminal provide the user with a more flexible and powerful way to manage and interact with the operating system than a graphical interface. They allow you to more precisely configure and control the operating system and perform complex operations that may be difficult or unavailable in the graphical interface.
