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
