加参数 I 有用不

terse

没考虑子目录 修正
ps不考虑效率

(Get-ChildItem  * -Recurse -include "*.txt") -Match "\[\d\d\]" | % {$_.MoveTo($_.DirectoryName + ($_.name -Replace '.*\[(\d{2})\].*','\$1.txt'))}
复制代码

加个参数 literalpath

(Get-ChildItem  * -Recurse -include "*.txt") -Match "\[\d\d\]" | foreach { move-item -LiteralPath  $_ ($_.DirectoryName + ($_.Name -Replace '.*\[(\d\d)\].*','\$1.txt'))}

这样试下呢？
无64位环境测试  请自行备份数据

@if(0)==(0) echo off
set "Sysdir=SysWOW64"
if /i "%PROCESSOR_ARCHITECTURE%" == "x86" if not defined PROCESSOR_ARCHITEW6432 set "Sysdir=System32"
set cscript="%Windir%\%Sysdir%\cscript.exe" //nologo //e:javascript
if "%~1" == "" (set "ph=%~dp0") else set "ph=%~1\"
for /f "delims=" %%i in ('dir/b/s "%ph%*[*]*.txt"^|%cscript% "%~f0"')do (
    echo,Ren %%i 2>nul
)
pause
goto :eof
@end
while (!WScript.StdIn.AtEndOfStream) {
    var f = WScript.StdIn.ReadLine()
    var arr = f.match(/(\[(\d{2})\])/)
    if (arr) WScript.echo('"' + f + '"','"' + arr[2] + '.txt"');
}

上面显示表明代码可正常运行
如要统配后缀可以改下这样试
虽然楼主放弃了 还是贴出吧

@if(0)==(0) echo off
set "Sysdir=SysWOW64"
if /i "%PROCESSOR_ARCHITECTURE%" == "x86" if not defined PROCESSOR_ARCHITEW6432 set "Sysdir=System32"
set cscript="%Windir%\%Sysdir%\cscript.exe" //nologo //e:javascript
if "%~1" == "" (set "ph=%~dp0") else set "ph=%~1\"
for /f "delims=" %%i in ('dir/b/s "%ph%*[*]*.*"^|%cscript% "%~f0"')do Ren %%i 2>nul
pause
goto :eof
@end
while (!WScript.StdIn.AtEndOfStream) {
    var f = WScript.StdIn.ReadLine()
    var e =/\.[^\.]+$/.exec(f);
    var arr = f.match(/(\[(\d{2})\])/)
    if (arr) WScript.echo('"' + f + '"','"' + arr[2] + e + '"');
}
