Delete File command

Linux Delete directory is very simple, many people are still accustomed to use rmdir, but once the directory is not empty, it fell into deep distress, now use the RM-RF command.

Direct RM is available, but add two parameters-rf that is: RM-RF directory name

-R is recursive down, no matter how many levels of directory, delete

-F is directly forcibly deleted, without any hint of meaning
