To: CCWan Brother, the command findstr /v /g:b.txt a.txt >1.txt seems to need to be changed to findstr /v /g:b.txt a.txt >>1.txt, which is more reasonable, right?

re youxi01 There is no need for that because it compares the entire content of the text at once, unlike for which loops sequentially. So even if there are many differences, it will all be output. This is also what I found after testing. Brother, you can give it a try.

Maybe you changed the contents of your a.txt and b.txt files, so it led to the "no response when running" you mentioned. 　　The code has been updated, try again?

Well, it's all right... Hehe``This is mainly to prevent ARP``In this case,``I'll re-collect the MACs of the following machines, and after comparison, I'll know which one is the culprit``,``Hehe``, everyone's methods are very good``Hehe``Learning in the process`` [ Last edited by chainliq on 2007-3-13 at 04:28 AM ]

The design of the landlord's question is problematic: If I am one of the macs, originally using 254 for the IP, I change to 100 and no other mac is using the 254 IP anymore, how do you detect me? It should be more reasonable to first judge the front and back macs and then see if the IP changes to report the MAC! Although I am very naive and can't understand some commands of the experts upstairs, I think the idea of the LZ is indeed problematic! [ Last edited by SunRiseBoy on 2007-6-29 at 12:57 AM ]

Everyone's code starts from comparing the differences between two texts, and I believe the LZ means the same.

Let me solve it with one sentence. findstr /v /g:b.txt a.txt >1.txt So powerful! I spent an entire night writing a batch script and couldn't get it done The version master solved it with one line of code...
