    NAME
           rm - remove files or directories

    SYNOPSIS
           rm [OPTION]... FILE...

    DESCRIPTION
           This  manual  page  documents  the  GNU version of rm.  rm removes each
           specified file.  By default, it does not remove directories.

           If the -I or --interactive=once option is given,  and  there  are  more
           than  three  files  or  the  -r,  -R, or --recursive are given, then rm
           prompts the user for whether to proceed with the entire operation.   If
           the response is not affirmative, the entire command is aborted.

           Otherwise,  if  a file is unwritable, standard input is a terminal, and
           the -f or --force  option  is  not  given,  or  the  -i  or  --interac‐
           tive=always  option is given, rm prompts the user for whether to remove
           the file.  If the response is not affirmative, the file is skipped.

    OPTIONS
           Remove (unlink) the FILE(s).

    **********************************************************************************************************

           -f, --force
                  ignore nonexistent files and arguments, never prompt
          #不进行询问(默认),强制删除


           -i     prompt before every removal    

          #删除之前进行询问,每删一个文件询问一次

           -I     prompt once before removing  more  than  three  files,  or  when
                  removing  recursively.  Less intrusive than -i, while still giv‐
                  ing protection against most mistakes
           #当删除文件超过三个以上时进行询问


           --interactive[=WHEN]
                  prompt according to WHEN: never,  once  (-I),  or  always  (-i).
                  Without WHEN, prompt always

          #是否进行询问,一次或者每次

    ***********************************************************************************************************


           -r, -R, --recursive
                  remove directories and their contents recursively

           -d, --dir
                  remove empty directories

           -v, --verbose
                  explain what is being done

    *************************************************************************************************************

           --one-file-system
                  when  removing  a hierarchy recursively, skip any directory that
                  is on a file system different from  that  of  the  corresponding
                  command line argument

          #跳过其他文件系统,对于多文件系统有重要的作用

           --no-preserve-root
                  do not treat '/' specially

           --preserve-root
                  do not remove '/' (default)


           --help display this help and exit

           --version
                  output version information and exit

           By default, rm does not remove directories.  Use the --recursive (-r or
           -R) option to remove each listed directory, too, along with all of  its
           contents.


           To  remove a file whose name starts with a '-', for example '-foo', use
           one of these commands:

                  rm -- -foo

                  rm ./-foo            #删除开头为 “-” 文件 =_+

           Note that if you use rm to remove a  file,  it  might  be  possible  to
           recover  some  of its contents, given sufficient expertise and/or time.
           For greater assurance that the contents are truly  unrecoverable,  con‐
           sider using shred.
