Since that we have mentioned earlier that there is actually some basic command that you would need to know which you can use in the Terminal on your Mac. Knowing the basics is actually the key for you to be able to advance your knowledge in any aspect such as your Terminal.
Keep in mind that every command is actually composed of three elements which are as follows.
• The command itself
• The argument – which tells the command you are entering on what source are you trying to enter.
• The option that modifies the output.
An example of which is that when you try to move a file from one folder to another, you would use the command “mv” and then enter the location that you would want to move it to, and then include the name of the file and the location where you would want to move it.

Part 3: Rules of Terminal

Just like any other program, Terminal also has its very own rules that you would be needing to follow. This way, you will be able to know if you are entering the right command or if you are having the right format.
The first thing that you need to know is that you have to make consider that every character matters. This includes the spaces on the command. So you always have to make sure that you are having the right spaces and that you have the right characters and that the letters are in the correct cases.

And once that you are on your target, just go ahead and press Return. And if you would want to interrupt a certain command that is running, then all you have to do is to type in Control-C.
Also, you have to remember that the command should also be entered in the right location. So if in case that you did not include the location in the command, then it will just go on the last folder wherein you last moved something. It can also go to the last command that you enter. You can use the command cd, following by the directory path.
Aside from that, there is also another way for you to be able to specify a certain location. All you have to do is to go to your Finder. After that, go ahead and or to the file or to the folder that you want and then drag it to the Terminal Window. Make sure that you are going to do this where you are typing the path.
Here is an example wherein you are actually going to make a new folder inside your Documents directory which can be called the “TerminalTest”.
