求一个简单一点的命令，谢谢大家。

谢谢你，我有点懂了。

qixiaobin0715

^[0-9]+.............行首一个或多个数字的集合
空格{0,}............. 0个或多个相连空格的集合

qixiaobin0715

去掉行号数字紧邻的所有空格，若想只删除一个空格，可将空格保留，去掉{0,}即可。

+空格{0,} 表示什么意思?

推荐试试 sed.exe 命令行工具

sed -r "s/^[0-9]+ {0,}//" 1.txt > 2.txt

简单点

@echo off
(for /f "tokens=1,* delims= " %%a in (a.txt) do echo,%%b)>b.txt
pause

参考http://bbs.bathome.net/thread-4580-1-1.html

@echo off
(for /f "delims=" %%a in (a.txt) do (
    set "var=%%a"
    setlocal enabledelayedexpansion
    set var=!var:* =!
    echo,!var!
    endlocal
))>b.txt
pause
复制代码

@Echo off&SetLocal EnableDelayedExpansion
(for /f "delims=" %%i in (1.txt)do set x=%%i&set x=!x:~6!&Echo !x!)>2.TXT
pause
