batch-file - 如何在每 (n) 行后插入空行？

Question

我有这个脚本:

@ECHO OFF

(FOR /f tokens^=2^ delims^=^"  %%a IN ('findstr /l "\<SOMETHING=\>" FILE.vav') DO (Echo | Set /p =%%a,)) >> Results.txt

现在的结果是这样的:

SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING, 

.但我需要插入 空行每 5 个结果后，结果应如下所示:

SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING,
//blank line
SOMETHING, SOMETHING, SOMETHING, SOMETHING, SOMETHING,
// blank line
SOMETHING, SOMETHING, SOMETHING, 

可能的解决方案是 FOR /L和 IF ，但我想不通。

Answer 1

尝试这个:

ECHO OFF &SETLOCAL 
(FOR /f tokens^=2^ delims^=^"  %%a IN ('findstr /l "\<SOMETHING=\>" FILE.vav') DO (
    <NUL Set /p =%%a,
    SET /a counter+=1
    SETLOCAL ENABLEDELAYEDEXPANSION
    SET /a counter%%=5
    IF !counter! equ 0 ECHO(
    ENDLOCAL 
    )
)>Results.txt
TYPE results.txt
