The abbreviation CLI means Command Line Interface, which in translation means "command-line interface". It is a text-based user interface that allows the user to communicate with an operating system or a computer program by entering text commands. Unlike a graphical user interface (GUI), all interaction here is done by typing commands into the command line, instead of clicking on icons and windows.
In the field of IT, and especially in server administration, CLI is an absolutely essential and indispensable tool. It allows administrators to efficiently manage and configure servers, often remotely via the SSH (Secure Shell) protocol. Thanks to CLI, software can be installed with high precision, system services monitored, files managed, complex tasks automated using scripts, and in-depth diagnostics performed. It is valued for its speed, low system resource consumption, and immense power for automation.
