linux下删除文件的命令是rm；

以下分两种介绍删除方法：

对于目录文件的删除：

#rf -rf filename

对于非目录文件的删除：

#rf filename

之所以对于目录文件的删除加上了强制参数是因为在linux对目录文件的删除是递归式的；

rm 的参数如下所示：

OPTIONS

Remove (unlink) the FILE(s).

-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 giv-

ing 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
