cmd - 在txtfile中间添加多行

Question

好的，这里有一个文件txt.txt

line1
line2
add after this line
line4
etc
etc

和另一个addthis.txt 包含多行的文件

我想在 addthis 之后添加所有这些行add after this line

我想知道的是我必须在这方面做出哪些改变才能完成它？？

任何帮助深表感谢。

Answer 1

@ECHO OFF
SETLOCAL
SET /p info="enter info : "
:: read addafter line
(
FOR /f "delims=" %%i IN (poison1.txt) DO (
SET addafter=%%i
FOR /f "delims=" %%n IN (' findstr /n "^" txtfile.txt') DO (
SET line=%%n
SETLOCAL ENABLEDELAYEDEXPANSION
SET line=!line:*:=!
ECHO(!line!
IF "!line!"=="!addafter!" TYPE your_multiline_addition.txt
ENDLOCAL
)
)
)>newfile.txt

FC newfile.txt txtfile.txt

GOTO :eof

只需要TYPE your_multiline_addition.txt而不是ECHO(%input%

（你也可以扔掉你的输入）

或者

你可以

TYPE "%info%"

如果您想输入包含附加内容的文件的名称

测试数据和结果：

======== poison1.txt ===========
"A line !of! ] many < & >var*ied %poison ^ char;ac(ters) | like "," a\nd+so=on"
======== extra_lines.txt ===========
extra line one
extra line two
extra line three
======== txtfile.txt ===========
line one 
line two 
line three
A line !of! ] many < & >var*ied %poison ^ char;ac(ters) | like "," a\nd+so=on

line 5 was blank - this is line FIVE
"A line !of! ] many < & >var*ied %poison ^ char;ac(ters) | like "," a\nd+so=on"
