批处理如何在文件中的字符串里面加一空格？

1130342432

现有一文本文件1.txt，内容为abcdefghijklmnopqrstuvwxyz,如何编写批处理使输出
a b c d e f g h i j k l m n o p q r s t u v w x y z？

CrLf

只有单字节字符的文本可以这样：

1. @echo off&setlocal enabledelayedexpansion
   
2. set n=1
   
3. for /f "tokens=1* delims=:" %%a in ('
   
4.    "cmd /u /c type 1.txt|more|findstr /n ."
   
5. ') do (
   
6.    if %%a neq !n! (
   
7.       echo;!str:~1!
   
8.       for /l %%b in (!n! 9 %%a) do if %%b neq !n! echo;
   
9.       set str=
   
10.    )
    
11.    set /a n=%%a+1
    
12.    set str=!str! %%b
    
13. )
    
14. echo;!str:~1!
    
15. pause
