What is command line tool?
A command-line tool is a type of software that is run from a command line interface (CLI) rather than a graphical user interface (GUI). This means that the user interacts with the tool using text-based commands, which are typed into a terminal or command prompt window. These commands are then executed by the tool, which performs the desired action and returns the results in the form of text output.
Command-line tools are often used for tasks that require a high degree of control or precision, such as managing files, running scripts, or performing advanced system tasks. They are also commonly used by developers for tasks such as building and deploying software, running tests, or debugging code.
