It is easy to create a file in Liunx so that there are any files that are at any time in the system, and users can delete them with the RM command. This command deletes the file or directory itself from the directory, and for the linked file, only the link is deleted and the original file remains unchanged. Http://www.aliyun.com/zixun/aggregation/18137.html "> options for deleting files and directories include:
 
-i-interaction. Prompt you to confirm the deletion. This option will help you avoid accidentally deleting files.
 
f coercion. Instead of interactive mode, delete files without prompting. Unless you know what you're doing, it's not always advisable to use this option.
 
-v-details. Displays the progress of the file deletion.
 
R. recursion. A directory and all of its files and subdirectories will be deleted.
 
To delete a file piglet.txt using the RM command, type:
 
RM piglet.txt
 
Another command to delete a directory that is more secure than using RM is the RMDIR command. This command does not allow you to use recursive deletion, so you cannot delete the directory containing the files.
