批量替换多级目录下所有txt内的指定字符（10元红包感谢）

bobocoolsky

需要批量替换多级目录下所有txt内的指定字符，不清楚如果批量修改指定目录下多个多级文件夹下的txt文件，求助，以下是找的单个修改的代码可以用，不知道如何修改for才行

<# :
cls&echo off&cd /d "%~dp0"
rem 将当前目录里的一个dat文件里的指定字符内容替换成其他指定字符内容
set #=Any question&set _=WX&set $=Q&set/az=0x53b7e0b4
title %#% +%$%%$%/%_% %z%
set "current=%cd%"&set "tmpfile=%tmp%\t.t"
dir /a-d-h/b "*.txt">"%tmpfile%"
powershell -NoProfile -ExecutionPolicy bypass "Get-Content -literal '%~f0'|Out-String|Invoke-Expression"
echo;%#% +%$%%$%/%_% %z%
exit
#>
$tmpfile=$env:tmpfile;
$outfolder=($env:current).trimend("\")+"\result";
if(-not (test-path -literal $outfolder)){[void][IO.Directory]::CreateDirectory($outfolder);}
$enc=[Text.Encoding]::GetEncoding('GB2312');
$files=[IO.File]::ReadAllLines($tmpfile, $enc);
if($files.Count -ge 1){$files[0];
$text=[IO.File]::ReadAllText($files[0], $enc);
$text=$text.replace(',', ' ');
$newfile=$outfolder+'\'+$files[0];
[IO.File]::WriteAllText($newfile, $text, $enc);
}

辛苦大神，只是代码测试出现以下错误，烦劳帮忙看一下，谢谢：

.txt和.bat需存为ansi/gb2312编码

<# :
cls&echo off&cd /d "%~dp0"&set "current=%cd%"
path %SYSTEMROOT%\System32\WindowsPowerShell\v1.0;%path%
powershell -NoProfile -ExecutionPolicy bypass "Get-Content -literal '%~f0'|Out-String|Invoke-Expression"
pause
exit
#>
$oldword=',';
$newword=' ';
$current=($env:current).trimend('\');
$enc=[Text.Encoding]::GetEncoding('GB2312');
$files=@(dir -literal $current -recurse|?{('.txt' -eq $_.Extension) -and ($_ -is [System.IO.FileInfo])});
for($i=0;$i -lt $files.length;$i++){
    write-host $files[$i].FullName.Substring($current.length);
    $text=[IO.File]::ReadAllText($files[$i].FullName, $enc);
    $text=$text.replace($oldword, $newword);
    [IO.File]::WriteAllText($files[$i].FullName, $text, $enc);
}
