Using RM to delete non-empty directories in Linux

I thought I should use the command rmdir
However, it was found that it could not delete the Non-empty directory.
Later found that the original should use the command RM-RF directory name
where the parameter-F indicates force. Using this parameter will not prompt you to delete it.

RM-RF Directory Name

R means to delete the directory, f meaning is force abbreviation, Force Delete, do not prompt.

If the directory is empty, you can delete it with the "RmDir directory name"
If the directory is not empty, you can delete it with the "Rm-r directory name"
