我有一系列试图进入数据库的 .txt 文件。

第 7 行“包含”破折号和空格的分隔。像 excel 这样的工具会根据整个文件尝试和空格分隔。但第 7 行之后的行在字段内有空格。

从一篇文章中，我发现我设法创建了一个 cmd.bat 脚本来删除前 6 行和页脚。现在我需要关于如何使用 row7“分隔”文件的建议。之后删除 row7 将是一个奖励。4 个字段的长度波动，因此固定字段长度不是选项。将不胜感激任何帮助。

试试这个（它可能很慢，没有改变）： 

@ECHO OFF &SETLOCAL ENABLEDELAYEDEXPANSION
SET "infile=file"
SET "outfile=out"
FOR /f %%a in ('^<"%infile%" find /c /v ""') do SET /a lline=%%a-9
FOR /f "usebackqskip=6delims=" %%a IN ("%infile%") DO IF NOT DEFINED line SET "line=%%a"
FOR %%a IN (%line%) DO (
    SET /a counter+=1
    FOR /f "delims=:" %%b IN ('(echo(%%~a^&echo(^)^|findstr /o $') DO SET /a $!counter!=%%b-2
)

(FOR /f "skip=6delims=" %%a IN ('findstr /n $ "%infile%"') DO IF %lline% gtr !cline! (
    SET "line=%%a"
    FOR /f "delims=:" %%b IN ("!line!") DO SET /a cline=%%b
    SET "line=!line:*:=!"
    SET /a cstart=0
    SET "Newline="
    FOR /l %%b IN (1,1,%counter%) DO (
        CALL SET "token=%%line:~!cstart!,!$%%b!%%"
        SET "flag=true"
        SET /a tstop=!$%%b!-1
        FOR /l %%c IN (!tstop!,-1,0) DO IF DEFINED flag IF NOT "!token:~%%c,1!"==" " (
            SET /a tstop=%%c+1
            FOR /f %%d IN ("!tstop!") DO SET "token=!token:~0,%%d!"
            FOR /f "tokens=*" %%d IN ("!token!") DO SET "token=%%d"
            SET "flag="
        ) ELSE (
            IF %%c equ 0 SET "token="
        )
        IF %%b equ 1 (SET "Newline="!token!"") ELSE SET "Newline=!Newline!,"!token!""
        SET /a cstart+=!$%%b!
    )
    ECHO(!Newline!
))>"%outfile%"
TYPE "%outfile%"

..输出：

这不适^"!%*=~用于 infile 中的特殊字符。

您最好在 Windows 上使用 awk并FIELDWIDTHS在BEGIN模式中设置。您可以将它与sed for Windows结合使用。

尝试使用限定符，即“或任何可以使您的应用程序或工具识别该列从这里开始的东西。它会忽略列中的分隔符。
