请教rm

ilwmin

find  -name  XXXX  -exec rm –rf {} \;
请教大神，在上面的命令中{} \:是干什么用的？

{}表示find命令查找到的内容。
\;表示命令的结束，就好比一句话最后需要一个标点符号断句一样。

-exec command ;
              Execute command; true if 0 status is returned.  All following arguments to find are
              taken to be arguments to the command until an argument consisting of ‘;’ is encoun-
              tered.  The string ‘{}’ is replaced by the current file name being processed every-
              where  it occurs in the arguments to the command, not just in arguments where it is
              alone, as in some versions of find.  Both of these constructions might need  to  be
              escaped  (with  a  ‘\’) or quoted to protect them from expansion by the shell.  See
              the EXAMPLES section for examples of the use of the ‘-exec’ option.  The  specified
              command is run once for each matched file.  The command is executed in the starting
              directory.   There are unavoidable security problems surrounding use of  the  -exec
              option; you should use the -execdir option instead.

;结尾是固定格式吧，\作用是转义字符  ，我是这么理解的，我是来打瓶酱油
