you can delete a folder using rmdir:
The folder you delete must be empty.
$ mkdir fruits
$ rmdir fruits
You can also delete multiple folders at once:
$ mkdir fruits cars
$ rmdir fruits cars
To delete folders with files in them, we'll use the more generic 'rm' command
which deletes files and folders, using the
-rf options:
$ rm -rf fruits cars
Be careful as this command does not ask for confirmation and it will
immediately remove anything you ask it to remove.
There is no bin when removing files from the command line, and recovering
lost files can be hard.
