Then we would type. In this case, the PowerShell will move assignment3. The move command will always delete the original name of the file when it is done. Sometimes we want to make a copy of a file.

There are hundreds of resources out there on how to learn to use the PowerShell in Windows. If you want to learn more, we suggest this popular tutorial as a starting point.
If have are having difficulty with the PowerShell, please see one of the course staff. They are available to help. On the Macintosh, the command shell is called the Terminal.
If it is not in your Dock where it belongs! We recommend putting it in your Dock immediately. This symbol is called the prompt, and it is a cue for you to type something into the Terminal.
To get the Terminal to do something, simply type in a command, and hit Return. As we mentioned above, the Terminal works a lot like the Finder. Because you often need to change your working directory, the three most important commands to know in the Terminal are pwd , ls , and cd.
Typing in pwd displays the current working directory. The command ls lists the contents files and folders in the working directory. An example of these two commands is shown below. When you type this command into the Terminal, you must give it two things: the command cd and the name of the folder you wish to go to. Using the example above, suppose you wish to switch the working directory to Desktop.
It is also possible to type cd by itself, without a directory name. If you do this, it will immediately put you back in your home folder. This is very helpful should you ever get lost while using the Terminal. If you are new to the Terminal, you might find yourself quickly getting tired of all the typing that you have to do. Fortunately, MacOS has tab completion to speed things up.
There are at least two things in your home directory that start with D: Desktop and Documents. MacOS does not know which one to complete to, so it lists the possibilities for you.
Tab autocompletion only works when the Terminal has enough information to uniquely pick one option from the current folder. Try doing this again with. We refer to these expressions as paths. Absolute paths are paths that do not depend on the working directory.
For example, if you wanted to go to your Applications directory which is just inside the root directory , you would type. Absolute paths are very important when you are trying to navigate to a different disk drive. To view the contents of this drive in the terminal, type. Make sure the terminal is in the home directory go home by typing cd by itself and type.
Look at the contents with ls. Now go back to the home directory again and type. The Terminal breaks up the commands that you type in by spaces. For example, the following should also work correctly:. If you use Tab Completion a lot, you will notice that this is the prefered way of handling spaces. If you do not learn anything else about the Terminal, you should learn this one trick which works on Windows as well.
If you take a folder and drag and drop it onto the Terminal, it will fill the window with the absolute pathname of that folder. Therefore, to quickly move the Terminal to a a specific folder, do the following:. This trick works on Windows and Linux as well. However, MacOS has an even faster trick that is unique to its operating system. Simply take the folder icon and drop it onto the Terminal icon in your Dock , and it will open a new Terminal window with that folder as its working directory.
This is a very useful skill and you will see your instructor use it often in class. Type it once, and nnn will display only entries that match what you type afterward, as you type it. Moving, deleting or copying files is delegated to the shell. Press "! When done, nnn will resume working from where you left it. You can also write your own script to extend nnn. Bookmarks must be set outside the program into an environment variable. This is not an exception.
Every nnn parameter is set in the same way, instead of writing it into one configuration file. Therefore, the easiest way to have a permanent nnn configuration is to set all its variables in your shell configuration file, following this example in the Arch Linux wiki. By default, ranger has three interlinked panes, which always show the parent directory, the current one and a preview of its contents Figure C.

Regardless of the layout, typing ":flat N" shows all the files in the current folder and all its subfolders up to the Nth level as one list.
