Programming experience: Several batch processing statements just concluded

I want to know which hosts are alive in a CIDR block, and I am too tired to use the ping255 machines.

For/L % I in (255,) Do ping 192.168.0.% I-l 1-N 1> result.txt
Ping 192.168.0.% I-l 1-N 1 255 and output the result to the result.txt File

Find "bytes = 1" "result.txt"
Find the rows with Bytes = 1 in the result.txt file and print them to the screen. Because the previous Ping specifies-L 1, the successful machine will have rows with Bytes = 1, only the result of request timeout is returned.

I remember when I was a child, I once spoke a lot before I learned programming. I used C ++ to do the same thing with batch processing!

It's so arrogant when you are young, but now it's possible that you can use rundll32 to call winapi and execute loops and judgments to implement simplicity.ProgramNow
