I am a new macOS Unix user. How do I remove a directory in Unix using the terminal applications?

Introduction: Everything is a file in Unix including the directory. A directory is nothing but a group of files (or data). One can group files as per our needs and setup.

How to delete a directory in Unix even when it is not empty

As I said earlier rmdir command remove the DIRECTORY(ies) if they are empty. But, how do you delete a full directory that has many files and sub-directories? The solutions is to pass the -r option to the rm command. The rm command syntax is as follows to delete a directory in Unix:
rm -r /path/to/dir/
rm -rf myDirName
rm -rfv /path/to/dir
rm -rfv ~/foo/
rm -ri myDirName

Where,

• -r – Remove directories and their contents recursively on Unix
• -f – Forceful option i.e. attempt to remove the files without prompting for confirmation, regardless of the file’s permissions.
• -v – Be verbose. Show what rm command doing with given directory/file names on Unix
• -i – Request confirmation before attempting to remove each file, regardless of the file’s permissions, or whether or not the standard input device is a terminal.
