RMDIR [/S] [/Q] [drive:]path
RD [/S] [/Q] [drive:]path
/S 除目录本身外，还将删除指定目录下的所有子目录和
文件。用于删除目录树。
/Q 安静模式，带 /S 删除目录树时不要求确认
C:\Documents and Settings\Administrator>rd /f
无效的命令行开关 - "f"。
zyd@HCC:~> rm --help
Usage: rm [OPTION]... FILE...
Remove (unlink) the FILE(s).
原来linux和window存在差异的！-----------谢谢提醒
-f, --force ignore nonexistent files, never prompt
-i prompt before every removal
-I prompt once before removing more than three files, or
when removing recursively. Less intrusive than -i,
while still giving protection against most mistakes
--interactive[=WHEN] prompt according to WHEN: never, once (-I), or
always (-i). Without WHEN, prompt always
--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
--no-preserve-root do not treat `/' specially
--preserve-root do not remove `/' (default)
-r, -R, --recursive remove directories and their contents recursively
-v, --verbose explain what is being done
--help display this help and exit
--version output version information and exit
