木林森X

Create a file hello.txt by using the following command.

$ touch hello.txt

Confirm that the file has been created successfully by listing the files.

$ ls

To create a copy of this file, enter the following.

$ cp hello.txt hellocopy.txt

List the files to confirm that a copy of the file has been created.

$ ls

Remove the hellocopy.txt file by entering the following delete command.

$ rm hellocopy.txt

List the files again to confirm that the file has been removed.

$ ls

The terminal will blindly carry out your commands without asking you to confirm the file to delete.  If you want to be prompted when you delete a file enter the following.

$ rm -i hello.txt

Press N because there is an additional trick left.  Enter the following but this time you will press the tab file.

$ rm -i he<PRESS TAB>

This should complete the file in the command line to read.

$rm -i hello.txt

Press Y to delete the file.

When create files it is always nice to keep things organised.  A directory will do just the job.  Enter the following.

$ mkdir myfiles

Create a file.

$ touch suntimebox.txt

List the files and folders to confirm that they have been created.

$ ls -lF

Move the suntimebox.txt file into the myfiles directory.

$ mv suntimebox.txt myFiles

List the files and folders again and take note that the suntimebox.txt file is missing.

$ ls -lF

It is missing from the current directory because it was moved into the myFiles directory.  Enter the following.

$ cd myFiles

$ ls -lF

The file should appear in the directory that was created.  Enter the following.

$ cd ..

Enter the pwd command to confirm your locations.

$ pwd

Confirm that you are in the /home/pi directory and enter the following.

$ rm myFiles

The output displays that you cannot remove ‘myFiles’ because it is a directory.  This is because a flag is needed.  Enter the following command.

$ rm myFiles -r

This will attempt to remove any files inside the myFiles directory before removing it.
