首先，我们需要开一个命令窗口，将gfind拖入。

然后按enter

然后会出现这一行字：
Rule (return for help):
输入要搜索的飞船所在的规则（B代表出生，S代表存活），比如b3s23。
然后会输出这样一坨东西：

里面出现的几个rle格式的东西就是飞船，速度在rle的上面。

现在要将里面的rle提取出来，只要按鼠标右键，选择Select All,按一下Enter，文字就复制到剪贴板上了。

然后用ctrl+V粘贴到记事本中，提取出rle，再放到golly中。

习题：寻找b36/s23中的小飞船，并鉴别哪些飞船不是b3/s23的飞船。

进file-preferences-edit，选always change rule if one is specified：

值得一提的还有Tim Coe的Knight搜索程序：
