逃生星号在Windows批处理文件的for循环 [英] Escape asterisk in Windows Batch File's FOR Loop

问题描述

当在Windows批处理文件运行一切以下code含有星号，这是跳过字符串的工作放在一边。检查通过数字传递的参数（即回声（％〜6 ），我可以看到星号 - 传递给时FOR循环，我有一个问题，它只是：

 关闭@echo
SETLOCAL ENABLEEXTENSIONS enabledelayedexpansion
拨打：CMD的毗连这是一个演示的CONCAT功能。 希望这会工作; 但事实并非如此，当我传递，*星号，人物
回音！CMD！@goto：结束
@goto：EOF
：的毗连
::连接字符串的一个给定的列表，但不包括其报价
:: 1  - 输出变量
:: 2 *  - 字符串Concat的
回声（％*
集/年XX = 0
设置Concat_tempFlag = 0
设置Concat_temp =
对于%%的（％*）在做（
    集/年XX =！XX！+1
    回音！XX！ - ％％一个
    如果！Concat_tempFlag！== 1（
        设置Concat_temp =！Concat_temp！%%〜一
    ）其他（
        设置Concat_tempFlag = 1
    ）
）
集％〜1 =％Concat_temp％
@goto：EOF：结束
回声（再见
退出/ B 0
 

我已经尝试 FOR / F（令牌= *）%% A有（'回声（％*'）做（如下建议：的Batch FOR用星号（及其变型），但没有运气循环。任何想法？在此先感谢。

解决方案

在这里找到解决方案：<一href=\"http://stackoverflow.com/questions/11685375/i-need-to-match-or-replace-an-asterisk-in-a-batch-environmental-variable-using\">I需要匹配或使用唯一的本地Windows命令在批处理环境变量替换星号*。这可能吗？

由于詹姆斯氏/ P>

When running the following code in a windows batch file everything works aside from the string containing the asterisk, which is skipped. Checking the passed parameters by number (i.e. echo(%~6) I can see the asterisk - it's only when passed to the FOR loop that I have an issue:

@echo off
setlocal enableextensions enabledelayedexpansion
call:Concat cmd "this is a demo" " of concat functionality." " Hopefully it will work;" " but it doesn't when I pass an" " * asterisk" " character"
echo !cmd!

@goto:end
@goto:eof


:Concat
::Concatenates a given list of strings without including their quotes
::1 - output variable
::2* - strings to concat
echo(%*
set /a xx=0
set Concat_tempFlag=0
set Concat_temp=
for %%A in (%*) do (
    set /a xx=!xx!+1
    echo !xx! - %%A
    if !Concat_tempFlag!==1 (
        set Concat_temp=!Concat_temp!%%~A
    ) else (
        set Concat_tempFlag=1
    )
)
set "%~1="%Concat_temp%""
@goto:eof

:End
echo(Bye
exit /b 0

I've attempted for /F (tokens=*) %%A in ('echo(%*') do ( as suggested here: Batch FOR loop with asterisk (and variations thereof) but with no luck. Any ideas? Thanks in advance.

解决方案

Found the solution here: I need to match or replace an asterisk * in a batch environmental variable using only native Windows commands. Is this possible?

Full code below:

@echo off
setlocal enableextensions enabledelayedexpansion
set DEFAULT_AsteriskMarker=_xAsteriskMarkerx_
call:Concat cmd "this is a demo" " of concat functionality." " Hopefully it will work;" " but it doesn't when I pass an" " * asterisk" " character"
echo !cmd!

@goto:end
@goto:eof


:Concat
::Concatenates a given list of strings without including their quotes
::1 - output variable
::2* - strings to concat
set Concat_StringsToConcat=%*
echo(%Concat_StringsToConcat%
call:AsteriskFix Concat_StringsToConcat
set /a xx=0
set Concat_tempFlag=0
set Concat_temp=
for %%A in (%Concat_StringsToConcat%) do (
    set /a xx=!xx!+1
    echo !xx! - %%A
    if !Concat_tempFlag!==1 (
        set Concat_temp=!Concat_temp!%%~A
    ) else (
        set Concat_tempFlag=1
    )
)
set "%~1="!Concat_temp:%DEFAULT_AsteriskMarker%=*!"
@goto:eof

:AsteriskFix
::http://stackoverflow.com/questions/11685375/i-need-to-match-or-replace-an-asterisk-in-a-batch-environmental-variable-using
set AsteriskFix_temp=!%~1!
if "%~2"=="" (
    set AsteriskFix_marker=%DEFAULT_AsteriskMarker%
) else (
    set AsteriskFix_marker=%~2
)
call:StrLen AsteriskFix_temp AsteriskFix_len
for /l %%x in (0,1,%AsteriskFix_len%) do if not "!AsteriskFix_temp:~%%x,1!"=="" if "!AsteriskFix_temp:~%%x,1!"=="*" (
    set /a AsteriskFix_plusone=%%x+1
    for /l %%y in (!AsteriskFix_plusone!, 1, !AsteriskFix_plusone!) do (
        set AsteriskFix_temp=!AsteriskFix_temp:~0,%%x!%AsteriskFix_marker%!AsteriskFix_temp:~%%y!
    )
)
set "%~1=!AsteriskFix_temp!"
@goto:eof

:StrLen
::http://www.dostips.com/DtCodeCmdLib.php#strLen
set "StrLen_str=A!%~1!"            &:: keep the A up front to ensure we get the length and not the upper bound
                                 ::it also avoids trouble in case of empty string
set "StrLen_len=0"
for /L %%A in (12,-1,0) do (
    set /a "StrLen_len|=1<<%%A"
    for %%B in (!StrLen_len!) do if "!StrLen_str:~%%B,1!"=="" set /a "StrLen_len&=~1<<%%A"
)
IF "%~2" NEQ "" SET /a %~2=%StrLen_len%
@goto:eof

:End
echo(Bye
exit /b 0
