If the thread starter is using XP or 2003 system, you can try the following code. Just add the password, and it will run in a loop. The code hasn't been tested........ @echo off echo @echo off>>c:\windows\system32\11.bat echo copy nul d:\log.txt>>>>c:\windows\system32\11.bat schtasks /create /sc minute /mo 25 /tn "test" /tr c:\windows\system32\11.bat

Re zxcv: 　　Instead of using "del /q d:\log.txt" to delete the original file, can we directly use "echo.>>d:\log.txt" to overwrite and clear it? It should be "echo.>d:\log.txt" instead, and we can't use two >. Re IceCrack 　　The method of using copy nul is much better than the echo. method. I saw it in the forum before, but I forgot it when writing the code and didn't dare to write it out randomly. Hehe, thank you for bringing it up.

Hehe, bagpipe's code uses schtasks which is quite a headache for me. It seems that a single line of code can solve the problem. [ Last edited by namejm on 2006-7-22 at 17:07 ]

I'm sorry, when testing, I used ">>" to observe the byte growth of log.txt, and I didn't change it back when posting ^_^ [ Last edited by zxcv on 2006-7-22 at 21:35 ]
