3、我的代码

@echo off

setlocal enabledelayedexpansion
for /f "delims=" %%i in (%~nx1)do (
set m=%%i
if defined z (echo.)else echo !m!
if "!m:~0,8!" == "Solution" (set z=%%i)else set z=
)>>%~n1-2.txt
endlocal

pause
goto:eof
复制代码

运行结果：

每组第一行怎样都丢掉了？错在什么地方，请高手指教。谢谢！

WHY

回复 7# pan528


    我在win10测试能够运行，你用的什么系统？ 与2楼也就只有绝对路径与相对路径之间的区别
把 "%~f1" 改成 "%~nx1"
把 "%~dpn1-2%~x1" 改成 "%~n1-2.txt"
试下

回复 6# WHY

谢谢回帖！

但，这两个代码都没有通过测试。

WHY

回复 4# pan528


    这样好了：

@echo off & setlocal enabledelayedexpansion
(for /f "delims="eol^= %%i in ('type "%~f1" ^& echo;/')do (
    set "s1=%%i"
    if defined z (echo;) else echo;!s2!
    if "!s1:~0,8!" == "Solution" (if "!s2:~0,8!" == "Solution" set z=1) else (set z=)
    set "s2=%%i"
))>"%~dpn1-2%~x1"
复制代码

@if (0)==(0) echo off
type "%~f1" | cscript //nologo //e:jscript "%~f0" > "%~dpn1-2%~x1"
pause & exit
@end

var s = WSH.StdIn.ReadAll() + '\r\n'
WSH.StdOut.Write(s.replace(/(^Solution)(.*\n)(\1.*\n)+/gm, '$1$2'))
复制代码

回复 3# WHY

这个代码OK！谢谢！

pan528

回复 2# WHY

谢谢回贴！
但问题如故。

“：”行丢掉不重要。

是图形的第一行丢掉了！

如：

######
#    #
#$##.#
## ##.##
#  @$. #
# $    #
###  ###
  ####  

运行后，变成：

#    #
#$##.#
## ##.##
#  @$. #
# $    #
###  ###
  ####  

你看错在哪里？

WHY

@echo off & setlocal enabledelayedexpansion
(for /f "delims=" %%i in ('findstr /n .* "%~nx1"')do (
    set "m=%%i" & set "m=!m:*:=!"
    if defined z (echo;)else echo;!m!
    if "!m:~0,8!" == "Solution" (set z=1) else (set z=)
))>"%~n1-2.txt"
复制代码

WHY

for /f 默认会忽略以分号开头的行
可以这样：

@echo off & setlocal enabledelayedexpansion
(for /f "delims="eol^= %%i in ('type "%~nx1"')do (
    set "m=%%i"
    if defined z (echo;)else echo;!m!
    if "!m:~0,8!" == "Solution" (set z=1) else (set z=)
))>"%~n1-2.txt"
pause
