    简单的说,patch就是利用diff制作的补丁来实现源文件(夹)和目的文件(夹)的转换。这样说就意味着你可以有源文件(夹)――目的文件(夹),也可以目的文件(夹)――源文件(夹)。下面介绍几个最常用选项: -p0 选项要从当前目录查找目的文件(夹) -p1 选项要忽略掉第一层目录,从当前目录开始查找。 在这里以实例说明: --- old/modules/pcitable Mon Sep 27 11:03:56 1999 +++ new/modules/pcitable Tue Dec 19 20:05:41 2000 如果使用参数-p0,那就表示从当前目录找一个叫做old的文件夹,在它下面寻找modules下的pcitable文件来执行patch操作。 如果使用参数-p1,那就表示忽略第一层目录(即不管old),从当前目录寻找modules的文件夹,在它下面找pcitable。这样的前提是当前目录必须为modules所在的目录。而diff补丁文件则可以在任意位置,只要指明了diff补丁文件的路径就可以了。当然,可以用相对路径,也可以用绝对路径。不过我一般习惯用相对路径。
