Command lines allow IT professionals an efficient way to interact with the computer and give it commands by just entering a few lines of text. Some notable functions of command lines include showing information, editing information, and testing connections. To show a list of a computer’s directories, Linux uses the ls command. With commands like these, those in the IT field can gain the information they need. In fact, using the help command in Windows can even help someone to know the commands they are able to use. If someone wants to delete a file or directory in Linux, they must enter rm. This exemplifies the ability to edit information using command lines. Finally, to test a connection in Command Prompt/Windows Powershell, the ping command must be used. Testing a connection is extremely important for deciding what to do based on the results. Thus, command lines are vital tools for managing a computer and computer network.
