[文本处理] 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：

@echo off&setlocal enabledelayedexpansion
set n=1
for /f "tokens=1* delims=:" %%a in ('
   "cmd /u /c type 1.txt|more|findstr /n ."
') do (
   if %%a neq !n! (
      echo;!str:~1!
      for /l %%b in (!n! 9 %%a) do if %%b neq !n! echo;
      set str=
   )
   set /a n=%%a+1
   set str=!str! %%b
)
echo;!str:~1!
pause
