1.bat內(nèi)容如下：- @echo off
- for /f delims=, tokens=2,3,4,5 %%a in ('type 1.txt') do (
- echo %%a>pul
- set sj=%%a
- if %sj% neq echo %%a%%b%%c%%d>>2.txt
- )
- pause

小弟的意思是以逗號作為分隔符，如果1.txt第二列的哪一行不為空的話就把那一行提取出來，放到2.txt里面，但是我這個批處理雙擊后本來應(yīng)該把D1和D7這兩行提取出來的，但是一閃而過了，也沒生成2.txt，不知道怎么回事，請各位大大給小弟看看，不勝感激！
