使用基于值的批处理文件从文本文件中删除回车

Question

我有一个要编辑的文本文件，因此要删除最后一行。我有以下代码：

for /f "delims=" %%a in (input.txt) do (
echo/|set /p ="%%a%"
)>>output.txt

输入：

GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;

输出：

GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;

现在，我想按第一个值分组编辑数据，以便获得以下输出：

GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;

Answer 1

如果将FOR /F "delims=" %%a in (input.txt) do …循环替换为等效的FOR %%a in … loop：

FOR %%a in …

输出：
第一次运行：@ECHO OFF
SETLOCAL EnableExtensions EnableDelayedExpansion
set "_gruppeName="
(
  for %%a in (
    "GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;"
    "GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;"
    "GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;"
    "GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;"
    "GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;"
    "GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;"
    "GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;"
    "GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;"
    "GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;"
  ) do (
    for /f "tokens=1 delims=;" %%A in ("%%~a") do (
      if /I NOT "%%~A"=="!_gruppeName!" (
        if defined _gruppeName echo(
        set "_gruppeName=%%~A"
      )
    ) 
    echo/|set /p ="%%~a"
  )
  echo(
)>>output.txt
REM debugging output follows
type output.txt
2>NUL del output.txt & D:\bat\CR\61816520.bat

下次运行：GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;

您的问题不清楚

基于...基于第一个值（GRUPPEA）

GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEC;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;

是否？还是只是在同一行上写重复项？

SORT

脚本使用@echo off
SETLOCAL EnableExtensions EnableDelayedExpansion

::VARIABLES
set "in=input.txt" IN file
set "out=output.txt" OUT file

set/a"#lines=0"
set "gruppe="
set "prevContent="

::Count lines
FOR /F %%L in ('
"findstr /N "^^" "%in%" %= do not skip empty lines =%"
') do set/a"#lines+=1" %= Get the # of lines =%


::Read IN via SET /P #LINES number of times
::Bangs (!) will be lost
<"%in%" >"%out%" (FOR /L %%# in (1 1 %#lines%) do (
    set "data="                           ::clear DATA
    set/p"data="                          ::read from IN
    FOR /F tokens^=1^ delims^=^;^ eol^= %%T in ("!data!") do set "gruppe=%%T"
    if NOT "!prevContent!" == "!gruppe!" (
        set "prevContent=!gruppe!"
        echo(
    )
    <nul set/p"=!data!"                    ::does not work with leading space, tabs, or equal signs
)) %= read file by lines via SET /P =%

exit /b
和FINDSTR /N循环来计算行数，以计算行数，这需要多次执行FINDSTR /N。
提示：

使用FOR /F代替有问题的FOR /F
• 使用管道SET /P非常慢，如
• @ jeb ECHO(所述。使用ECHO(代替
