Windows批處理 - 延遲擴展刪除感嘆號

Question

我寫了批處理腳本將CSS文件複製到某個目錄，問題是當我在目標目錄中打開CSS文件時，會刪除感嘆號。

原來的CSS包含感嘆號如樣式：

.foo 
{ 
    color: pink !important; 
} 

我的CSS結果變得

.foo 
{ 
    color: pink important; 
} 

我看着這一現象的根本原因和依據：exclamation point being removed constantly in batch file

但我無法弄清楚我需要在哪裏禁用延遲擴展。

僅供參考，我的一批是做如下：

1. 由逗號分隔每個主題串中，找到啓動和某些字符串相匹配的行號結束。

2. 現在我有開始和結束行號（例如500和1000）

3. 拷貝除了線500和1000

4. 之間

定稿文件被複制到目的地目錄中的文件內容

請讓我知道，如果您需要更多的澄清，在此先感謝。

UPDATE

下面是我的解決方案，根據配置的建議。不同的是，按照說明， 在腳本開始處設置了EnableDelayedExpansion，以便對整個批處理作用域產生影響，然後僅在其應用的位置設置DisableDelayedExpansion。

我把它放在這裏是我，你......

(for /F "tokens=1* delims=:" %%a in ('findstr /N "^" "Batch_tmp\%fileName%_tmp.css"') do (
    SETLOCAL DISABLEDELAYEDEXPANSION 
    if %%a lss %start% echo(%%b 
    if %%a gtr %end% echo(%%b 
    ENDLOCAL 
)) > Batch_tmp\!fileName!.css 

，但不保證......由OP :(

結果令人失望這裏是我的測試設置：

@ECHO OFF 
SETLOCAL ENABLEDELAYEDEXPANSION 
:: force directories, start and end 
SET runtime_dest=c:\temp 
SET filename=test 
SET start=2 
SET end=4 

:: create batch_temp & clear 

MD "%cd%\Batch_tmp" 2>NUL >NUL 
DEL "%cd%\Batch_tmp\*?*" /F /Q 

:: make copy of original .css 
xcopy "%RUNTIME_DEST%\%filename%.css" "%cd%\Batch_tmp" /y /z /r 

echo creating tmp copy... 
rem Rename the file so we can modify and create finalized version 
ren "Batch_tmp\%fileName%.css" "%fileName%_tmp.css" 

echo coping all line except section... 
rem Copy all lines, except the ones in start-end section 
(for /F "tokens=1* delims=:" %%a in ('findstr /N "^" "Batch_tmp\%fileName%_tmp.css"') do (
    if %%a lss %start% echo(%%b 
    if %%a gtr %end% echo(%%b 
)) > Batch_tmp\!fileName!.css 
rem Copy all lines, except the ones in start-end section 
(for /F "tokens=1* delims=:" %%a in ('findstr /N "^" "Batch_tmp\%fileName%_tmp.css"') do (
SETLOCAL disabledelayedexpansion 
    if %%a lss %start% echo(%%b 
    if %%a gtr %end% echo(%%b 
ENDLOCAL 
)) > Batch_tmp\!fileName!WITHSETLOCAL_ENDLOCAL.css 

ECHO ============================ 
ECHO Batch_tmp\%fileName%_tmp.css 
TYPE Batch_tmp\%fileName%_tmp.css 
ECHO =======^^^^^^^^=================this is the original file 
ECHO Batch_tmp\%fileName%.css 
TYPE Batch_tmp\%fileName%.css 
ECHO =======^^^^^^^^=================this is the result with delayed expansion enabled 
ECHO Batch_tmp\%fileName%WITHSETLOCAL_ENDLOCAL.css 
TYPE Batch_tmp\%fileName%WITHSETLOCAL_ENDLOCAL.css 
ECHO ========^^^^^^^^================this is the result with the advised setlocal/ENDLOCAL IN place 
GOTO :eof 

個

和結果：

C:\temp\test.css 
1 File(s) copied 
creating tmp copy... 
coping all line except section... 
============================ 
Batch_tmp\test_tmp.css 
.foo 
omit me 
and me 
and me 
{ 
    color: pink !important; 
} 
=======^^^^=================this is the original file 
Batch_tmp\test.css 
.foo 
{ 
    color: pink important; 
} 
=======^^^^=================this is the result with delayed expansion enabled 
Batch_tmp\testWITHSETLOCAL_ENDLOCAL.css 
.foo 
{ 
    color: pink !important; 
} 
========^^^^================this is the result with the advised setlocal/ENDLOCAL IN place
