So if I were to do something like cd and then App Dev you could see it can't figure out what I'm trying to do because it thinks app is the thing I'm trying to go into not App Dev. Spaces are very important in Terminal because they are divisions between commands and other parts of what you're trying to do.
What happens if there's a space in the name. But I'm being very specific about which app I want to use in case there were several apps that could open that type of file. Then the file and it would do the same thing in this case. I could have specified the app name by doing open -a and then the name of the app like that. You could see it opens it up and does it in its default app. Now if I wanted to open a file I could use Open instead of -a for application I'll just use the name of the file. But launching them is something I could do here in Terminal.

So the applications, they are still graphical applications with windows and all of that. So if I wanted to do TextEdit I can just type TextEdit and it would launch the app here ready for me to open a file. So, for instance, to launch an application I would type Open and then I would do dash a and then type the name of the app. Now in addition to actually looking around at things you can actually do things like Launch Applications. Even the 1 that is actually a file and not a folder. But if I go to my Documents folder I can see exactly the same things here. I can see now the graphical interface actually has the document and Desktop folders in iCloud. Let me go down into the documents folder and now when I do ls -l I see the list of everything that's in there. So cd and if I want to go down I just type the name of the folder. If I want to navigate around I could use CD for change directory. So you can see how it is basically the same as in here. Putting each thing, in this case folders, on a separate line with information about each one. The command here is ls and dash l is the modifier. The dash and then a letter or word is a modifier by the command. I could list this another way by doing ls and then dash l. That's the same thing that is listed here.
In the Finder if I go to my Home folder and then I look at what's there you can see these folders that are there. You can list the files that are there with the ls command. You see I'll just type that, press return, and it will show me I'm in my User's Folder in my Home folder which is called MacMost. You can find out where by using the command pwd.
So when you're working in Terminal you are always at a certain location. This is just another way, besides the graphical user interface, to control your Mac. While you may be tempted to think that this is what's happening under the hood of your Mac that's not exactly true. You don't even have to use your Mouse or Trackpad at all. It's a Unix-like command line interface that allows you to interact with your Mac just by typing and reading text. What you actually have here is called a shell. You basically type into it and press Return to execute commands. When you launch it you get a window that looks like this. You can just run it by double clicking on that or you can use any of the normal ways to launch it. Then go all the way down to the Utilities folder and it's in there. If you want to see where it's located just create a new Finder window and go to the Applications folder. So the Terminal is an app that you can find on your Mac.
