One Linux command per day-RM

The RM command, used in Linux to delete files or directories, is a common command that deletes one or more files or directories in a directory, and it can delete all files and subdirectories under a directory. For linked files, only the links are deleted and the original files remain unchanged.

The RM command is a dangerous command, because the delete operation can not be reversed, so in the file or directory delete operation should be particularly careful, think clearly and press ENTER!

Command format:

RM [option] Files/diretoies

Command parameters:

-F,--force #忽略不存在的文件, delete directly, no longer prompt.

-I, #删除前提示, the RM under the command line is aliased, alias rm= ' Rm-i '

-R,-R,--recursive# recursively deletes all contents of the directory.

Command instance:

1. Delete files from 5 days ago
