Linux terminal commands. Part 1

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

What are 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: allow you to navigate the file system, create and delete files and directories, change their permissions, copy and move files.
2. Start and manage processes: allow you to start and terminate processes, check their status, suspend and resume their execution.
3. Networking: allows you to check the availability of hosts on your network, configure network interfaces, establish secure connections to remote servers, and perform other networking 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: allow you to perform various administrative tasks, such as installing and updating programs, configuring hardware, and monitoring the system.
6. Task automation: can be used in scripts and command files to automate tasks and create automatic procedures.

Commands in a terminal provide the user with a more flexible and powerful way to control and interact with the operating system than a graphical interface. They allow for more precise customization and control of the operating system and the ability to perform complex operations that may be difficult or inaccessible in a graphical interface.
