[文本处理] 批处理将目录下txt文件移动到以txt文件第一个连续字母命名的文件夹中

cckkaa888

将目录下txt文件移动到该目录下子文件夹{以txt文件第一个连续字母命名的，连续字母不包含一个字母的}中，如果没有就创建这个文件夹并且移动。
例如
将"123_zhangsan456@张三abc.tx"t移动到"zhangsan"文件夹中,
将"h-123lisi@李四.txt"移动到"lisi"文件夹中

WHY

PowerShell "dir *.txt -file | ?{$_.BaseName -match '[a-z]{2,}'} | forEach {$fd=$matches[0]; md $fd -ea SilentlyContinue; mv $_.FullName -Dest $fd}"
复制代码

@if(0)==(0) echo off
for /f "tokens=1*" %%i in ('dir /b /a-d *.txt ^| cscript -nologo -e:jscript "%~f0"') do (
    md %%i\ 2>nul
    move "%%j" %%i\
)
pause & exit/b
@end

while (!WSH.StdIn.AtEndOfStream) {
    var f = WSH.StdIn.ReadLine();
    var m = f.slice(0,-3).match(/[a-z]{2,}/i);
    if(m) WSH.Echo(m[0] + ' ' + f);
}

凡是提供正则匹配替换方法的脚本（如jscript/vbs/powershell/python/...）均可增援纯P代码以便其整个脚本代码轻量化...
以下代码调用jscript正则替换方法，存为test.bat，置于目标文件（*.txt）所在目录下运行...

@set @x=1 /* &@echo off
for /f "delims=" %%a in ('dir /b/a-d *.txt') do for /f "delims=" %%d in (
	' cscript /nologo /e:jscript "%~f0" "%%a" ') do (md "%%d" 2>nul & move /y "%%a" "%%d\")
pause&exit/b */
v = WSH.arguments; WSH.echo(v(0).match(/[a-z]{2,}/i)[0]); WSH.quit();

给一个直接用递归方法 ‘截取文件名第一个多字母字段’ 的版本
以下代码存为 test.bat 置于目标文件（*.txt）所在目录下运行...

@echo off
for /f "delims=" %%a in ('dir /b/a-d *.txt') do (
	set "s=%%a"&set "$a=%%a" &setlocal enabledelayedexpansion
	set "_s="&set "_k=" & (call :getstr)
	md "!_s!" 2>nul & move /y "!$a!" "!_s!\" & endlocal
)
pause&exit/b
:getstr
	set "c=!s:~,1!" &if "!c!" geq "a" if "!c!" leq "Z" (
