Command Line Tools are essential software applications that allow users to interact with their operating system through text-based commands. Unlike graphical user interfaces, these tools provide a more direct and efficient way to perform tasks such as file manipulation, system monitoring, and software installation. Popular examples include Bash, PowerShell, and Git. These tools are particularly favored by developers and system administrators for their speed and flexibility. By using commands, users can automate repetitive tasks, manage system resources, and access advanced features that may not be available through standard graphical interfaces. Mastering these tools can significantly enhance productivity and system control.
