Question

我通过搜索这个网站并学习了Windows批处理脚本的荒谬语言，取得了很大的进展，但我现在处于困境。我有一个文本文件，其行数可变，每个行看起来像：

AA8315,"United States",N777AN,"American Airlines",AAL98,B772,"Boeing 777-223",AAL,"2013-06-11 23:30:47.923","2013-06-12 00:01:14.459"

我的批处理文件：

set THEDATE=2013-06-12
set THEDATABASE=c:\Kinetic\BaseStation\Basestation.sqb
set THECSVFILE=c:\Flights.csv
set THEOUTPUTFILE=c:\FlightsNew.csv
set THISLINE=""

if exist %THECSVFILE% del %THECSVFILE%
if exist %THEOUTPUTFILE% del %THEOUTPUTFILE%

:: allow time for the csv file to be deleted
timeout /t 2 /nobreak

c:\sqlite3.exe -header -csv %THEDATABASE% "select Aircraft.ModeS, Aircraft.ModeSCountry as Country, Aircraft.Registration as Reg, Aircraft.RegisteredOwners as Owner, Flights.Callsign, Aircraft.ICAOTypeCode as Type, Aircraft.Type as Model, Aircraft.OperatorFlagCode as 'Op Flag', Flights.StartTime as 'First Seen', Flights.EndTime as 'Last Seen' from Aircraft INNER JOIN Flights ON (Aircraft.AircraftID=Flights.AircraftID) where Flights.EndTime like '%THEDATE% %%' order by Flights.EndTime DESC;" >> %THECSVFILE%

::allow time for the csv to be written to file
timeout /t 5 /nobreak

::read %THECSVFILE% and loop through each line
for /F "usebackq tokens=* delims=" %%A in (%THECSVFILE%) do (
    set the_line=%%A
    call :process_line
)

:process_line
for /F "usebackq tokens=1,2,3,4,5,6,7,8,9,10 delims=[,]" %%1 in (%the_line%) do (
    set hexcode=%%1
    set country=%%2
    set reg=%%3
    set owner=%%4
    set callsign=%%5
    set planetype=%%6
    set model=%%7
    set opflag=%%8
    set firstseen=%%9
    set lastseen=%%10
    set THISLINE=%hexcode%,%country%,%reg%,%owner%,%callsign%,%planetype%,%model%,%opflag%,%firstseen%,%lastseen%
    echo %THISLINE% > %THEOUTPUTFILE%
)

（我将令牌分配给变量，因为我稍后会进行额外的验证和格式化。我需要先让这部分工作！）

执行时，脚本确实循环遍历文件的每一行，但它似乎没有将%%1分配给变量hexcode。

执行命令的输出如下所示：

C:\>for /F "usebackq tokens=1,2,3,4,5,6,7,8,9,10 delims=[,]" %1 in (AA8315 "United States" N777AN "American Airlines" AAL98 B772 "Boeing 777-223" AAL "2013-06-11 23:30:47.923" "2013-06-12 00:01:14.459") do (
set hexcode=%1
 set country=%2
 set reg=%3
 set owner=%4
 set callsign=%5
 set planetype=%6
 set model=%7
 set opflag=%8
 set firstseen=%9
 set lastseen=%10
 set THISLINE=,"United States" ,N807FD ,"Fedex Express" ,FDX1378 ,,"Airbus A310-324" ,FDX ,"2013-06-12 22:56:54.639" ,"2013-06-12 23:05:31.822"
 echo ""  1>c:\FlightsNew.csv
)
The system cannot find the file AA8315.

非常感谢任何帮助！

Answer 1

这可以在这里工作：


    for /f "tokens=1-10delims=," %%a in ("AA8315,"United States",N777AN,"American Airlines",AAL98,B772,"Boeing 777-223",AAL,"2013-06-11 23:30:47.923","2013-06-12 00:01:14.459"") do (
     set hexcode=%%a
     set country=%%b
     set reg=%%c
     set owner=%%d
     set callsegn=%%e
     set planefype=%%f
     set model=%%g
     set opflag=%%h
     set firstseen=%%i
     set lastseen=%%j
     set THISLINE=%%a,%%b,%%c,%%d,%%e,%%f,%%g,%%h,%%i,%%j
    )
    >"c:\FlightsNew.csv" echo %THISLINE%

我不确定，为什么你需要这些令牌。

Answer 2

您只能使用元变量中的字母（代码中为%%1） - 但小写和大写字母是不同的。

是的，您可以使用其他一些字符，但"tokens=1-10"（这是1,2,3的更简单版本）可用的连续块是a..z和A..Z < / p>

％0 ..％9保留用于批处理或批处理过程的参数。

Answer 3

我在for循环中一直遇到逗号分隔值的问题。以下是我为使代码工作所做的工作。

Test.txt的

AA8315,"United States",N777AN,"American Airlines",AAL98,B772,"Boeing 777-223",AAL,"2013-06-11 23:30:47.923","2013-06-12 00:01:14.459"

BatchFile.bat

set THECSVFILE=test.txt

::read %THECSVFILE% and loop through each line
for /F "usebackq tokens=* delims=" %%A in (%THECSVFILE%) do (
    set the_line=%%A
    call :process_line
)
goto TheEnd

:process_line
for /F "usebackq tokens=1,2,3,4,5,6,7,8,9,10 delims=~" %%1 in ('%the_line:,=~%') do (
    set hexcode=%%1
    set country=%%2
    set reg=%%3
    set owner=%%4
    set callsign=%%5
    set planetype=%%6
    set model=%%7
    set opflag=%%8
    set firstseen=%%9
    set lastseen=%%10
    set THISLINE=%hexcode%,%country%,%reg%,%owner%,%callsign%,%planetype%,%model%,%opflag%,%firstseen%,%lastseen%
    echo %THISLINE% > %THEOUTPUTFILE%
)

:TheEnd

请注意：process_line for循环。我不得不在%the_line%周围添加单引号，因此它没有尝试将字符串解释为文件名。然后我用〜字符替换了所有逗号，并使用〜字符作为分隔符。它可能无法准确处理所有数据（如果它包含单引号或〜字符），但它可以使用这一条记录并让您再次朝正确的方向移动。
