前些天為了測(cè)試個(gè)東西，寫(xiě)的監(jiān)控某個(gè)目錄下文件變化的小程序，稍微修改下就成了類(lèi)似tripwire的工具。
編譯： javac triproot.java
運(yùn)行：java triproot -init [Dir you want init] [Output file name]
java triproot -check [Dir you want check] [Trip file,that must be init early]
在windows2k、window2003、AS5.1上測(cè)試過(guò)，linux下編譯運(yùn)行要改個(gè)字符，注釋里有。
