有文本a.txt如下: aaaaaaa aaaa bbbbbb ccccccccccc dddd aa aaaaaaa bbbbbbbb cccccccccc ddddddddddddd eeeeeee aaaaaaaaaaaa bbbbbbbbbbb cccccccccccccccccccc aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aa aaaaaaaaaaaaaaaaaaaaaaaaaaaa bbbbbbbbbb aaaaaaaaa ccccccccc bbbbbbbbbbbbb ddddddddddddddddd 通过批处理查找出文本中字符数(不含空格)最多的行并输出,很明显就是复制内容到剪贴板代码: aaaaaaaaa ccccccccc bbbbbbbbbbbbb ddddddddddddddddd 要求: 1 不生成临时文件 2 代码简洁,高效,通用性好 3 加分仍以思路为重 浅默: 复制代码 代码如下: @echo off Setlocal Enabledelayedexpansion set n=0 for /f "delims=" %%i in (a.txt) do ( set "ke=%%i" set ke1=!ke: =! set m=0 call :1 ) echo %wang% pause goto :eof :1 if not "!ke1:~%m%,1!"=="" set /a m+=1&goto 1 if %m% gtr %n% set n=%m%&set wang=%ke% goto :eof batman: 复制代码 代码如下: @echo off set num=0 for /f "delims=" %%i in (a.txt) do set "str=%%i"&call,set "str=%%str: =%%"&call :lp "%%i" call,echo %%_%num%%% %num%个字符 pause>nul&goto :eof :lp set "str=%str:~1%"&set /a n+=1 if defined str goto lp if %n% geq %num% set "num=%n%"&set "_%num%=%~1" set "n=0" |
