推荐答案

使用Findstr /N为文件的行编号

> findstr /N ".*" test.txt
1:0181830207709014000015576526S00000140000014000001242017
2:0052500056661095000015576527S00000950000095000001242017
3:0157020294103030000015576528S00000300000030000001242017
4:2397870060994031500015576529S00000315000031500001242017
5:2466260219154015000015576530S00000150000015000001242017

和For /f循环以解析输出，在冒号处将其拆分为数字的vars %%A和行内容的%%B.如果数字是2，请插入多余的行.

And a For /f loop to parse the output, splitting at the colon into vars %%A for the number and %%B for the line content. If the number is 2 insert the extra line.

@Echo off
Set "File=Test.txt"
Set "NewFile=TestNew.txt"
(
  For /f "Tokens=1*Delims=:" %%A in (
    'Findstr /N ".*" "%File%"'
  ) Do If %%A Equ 2 (
    Echo:insert me a new line before
    Echo:%%B
    Echo:insert me a new line below
  ) Else (
    Echo:%%B
  )
) >"%NewFile%"

EDIT 更改了后续读者的逻辑.样本输出:

EDIT changed the logic for followup readers. Sample Output:

> type TestNew.txt
0181830207709014000015576526S00000140000014000001242017
insert me a new line before
0052500056661095000015576527S00000950000095000001242017
insert me a new line below
