1. rm command parsing
The rm command can delete one or more files or directories in a directory, or delete all files and subdirectories of a directory and its subordinates. For linked files, just delete the entire linked file, leaving the original file unchanged.
Note: Use the rm command with extreme care. Because once a file is deleted, it cannot be recovered . Therefore, before deleting the file, it is best to look at the contents of the file again to determine whether it is really necessary to delete it. The rm command can be used with the -i option, which is especially useful when deleting multiple files using file extension characters. Using this option, you will be asked to determine whether you want to delete one by one. At this point, you must type y and press Enter to delete the file. The file is not deleted if you just press enter or other characters
