Power shell命令的工作就像一个魅力

(
test.txt | ForEach-Object { $_ -replace "foo", "bar" } | Set-Content test2.txt
)

我不认为有任何内置命令可以做到这一点。我建议你下载Gnuwin32或UnxUtils，并使用sed命令(或只下载sed):

sed -c s/FOO/BAR/g filename

下面是我在Win XP上发现的一个解决方案。在我运行的批处理文件中，我包括以下内容:

set value=new_value

:: Setup initial configuration
:: I use && as the delimiter in the file because it should not exist, thereby giving me the whole line
::
echo --> Setting configuration and properties.
for /f "tokens=* delims=&&" %%a in (config\config.txt) do ( 
  call replace.bat "%%a" _KEY_ %value% config\temp.txt 
)
del config\config.txt
rename config\temp.txt config.txt

替换后的。bat文件如下所示。我没有找到在同一个批处理文件中包含该函数的方法，因为%%a变量似乎总是给出for循环中的最后一个值。

replace.bat:

@echo off

:: This ensures the parameters are resolved prior to the internal variable
::
SetLocal EnableDelayedExpansion

:: Replaces Key Variables
::
:: Parameters:
:: %1  = Line to search for replacement
:: %2  = Key to replace
:: %3  = Value to replace key with
:: %4  = File in which to write the replacement
::

:: Read in line without the surrounding double quotes (use ~)
::
set line=%~1

:: Write line to specified file, replacing key (%2) with value (%3)
::
echo !line:%2=%3! >> %4

:: Restore delayed expansion
::
EndLocal

创建文件replace.vbs:

Const ForReading = 1    
Const ForWriting = 2

strFileName = Wscript.Arguments(0)
strOldText = Wscript.Arguments(1)
strNewText = Wscript.Arguments(2)

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile(strFileName, ForReading)
strText = objFile.ReadAll
objFile.Close

strNewText = Replace(strText, strOldText, strNewText)
Set objFile = objFSO.OpenTextFile(strFileName, ForWriting)
objFile.Write strNewText  'WriteLine adds extra CR/LF
objFile.Close

要使用这个修改后的脚本(我们称之为replace.vbs)，只需在命令提示符中键入类似于下面的命令:

cscript替换。vbs "C:\Scripts\Text.txt" "Jim " "James "

(

)

对我来说，为了确保不改变编码(从UTF-8)，保持重音…唯一的方法是在之前和之后提到默认编码:

powershell -Command "(gc 'My file.sql' -encoding "Default") -replace 'String 1', 'String 2' | Out-File -encoding "Default" 'My file.sql'"
