@echo off
find "worldcup" e:\files\test.txt
if ERRORLEVEL 1 echo String "worldcup" has already existed in file "e:\files\test.txt"
pause

test.txt内容为:
worldcup
Euro Championship
Aisa Championship

在test.txt中存在的worldcup,为什么用上诉批处理，不能输出 存在提示呢？

@echo off
find "worldcup" e:\files\test.txt>nul
if ERRORLEVEL 0 echo String "worldcup" has already existed in file "e:\files\test.txt"
pause

　　楼主对错误码的理解有问题，如果错误码为1，一般是表示执行失败。
