Windows 命令提示符：如何传递多行字符串参数

Question

I have a program that accepts a string parameter. I create a batch file that executes the program and a multiline string paramter. I also have a second parameter after the multiline string.

C:\>MyProgram "This is a
multiline text" parameter2

When I run this, only the first line of string is included in the command and the subsequent lines and the second parameter are ignored. Is there any way to pass multiline string parameters?

Answer 1

Your question is duplicate to - Windows: How to specify multiline command on command prompt?

In the Windows Command Prompt the ^ is used to escape the next character on the command line.

For example, (the More? being a prompt):

C:\>cd "c:\Program Files" ^
More? "\Common Files"

C:\>MyProgram "This is a " ^  
More? "multiline text" parameter2

Answer 2

This routine will write multiple lines to text file ASM.txt in the drive and directory of F:\\Backup_Info . Note that it will give a line space using the space then ^ symbol as shown, a line space is required between each statement:

(echo To Do is to Understand^

Who Dares Wins^

 ^

Baz) > F:\Backup_Info\ASM.txt

Answer 3

You can save ^ 's output as a variable

set br= ^
<</br (newline)>>
<</br>>

example:

@echo off
setlocal enableExtensions enableDelayedExpansion
rem cd /D "%~dp0"
set br= ^


rem br, can't be saved to a var. by using %..%;


set "t=t1!br!t2!br!t3"

for /f "usebackq tokens=* delims=" %%q in ('!t!') do (
    echo %%q
)


:scIn
rem endlocal
pause
rem exit /b

; output:

t1
t2
t3
