rm command. rm is commonly used commands, functions of the command to delete a directory one or more files or directories, it can also be a directory and all its files and subdirectories are deleted. For the linked file, just delete the link, the original files remain unchanged.
rm is a dangerous command, when used with special care, especially for the novice, otherwise the whole system will be destroyed in this command (such as in the implementation of rm * -rf / (root directory)). So, we'd better look for confirmation before executing rm in which directory, in the end you want to delete something, to keep a cool head during the height of the operation.
