With this in mind, don’t be alarmed if you notice that you can't use your trackpad or mouse to navigate across command lines. Navigate with the arrow keysĪrrow keys are the only way to navigate the Terminal. Additionally, other factors like spelling and capitalization also affect how commands execute. Take note of charactersĮvery character is important in a command - including the spaces (or the lack of spaces) at the beginning and end. Below are a few tips that you should remember when using Terminal. Thankfully, there are plenty of ways to make it easier. Using Terminal for the first time can be challenging. Usually located at the end of the command, a single command can have anywhere from zero to several arguments to run. While it sounds a little aggressive, the main job of the argument is to instruct the utility where to perform its action. You can identify the flag by the dash, or dashes, that appear before it. Usually, the flag appears after the utility and before the argument. The flag is a part of the command line that gives the utility options or preferences. Utilities can run on their own or in tandem with single or multiple flags or arguments. The utility is used to get information, list directories, display content, and make changes to files like copying, moving, and deleting them. However, the utility is always required to run a command. Depending on the type of command, flags and arguments are optional. Most types of commands will have three parts – utility, flags, and arguments. You can even create custom bash commands called “aliases.” In the form of functions, an alias can execute simple and complex instructions.
