This is a question for Linux:

Copy all regular files (not directories) from your parent directory into your home directory.

You must use shell expansion characters to accomplish this. You don't know your present working directory or your user name.

The answer must be a single command.

Hints:

You need to use a separate shell expansion path for hidden and non-hidden files.

Do not use the -r option so directories are not copied.

Use an appropriate symbol for home directory.
