我需要能够通过NAME(而不是按顺序)将参数传递给Windows批处理文件。我的目的是为最终用户提供以任何顺序传递参数的灵活性,批处理文件仍然可以处理它们。
让我的问题更清晰的一个例子:
在命令行中,用户执行以下操作:
somebatchfile.bat originalFile.txt newFile.txt
在somebatchfile.bat
里面有一个简单的语句可以将原始文件(第一个参数%1%)的内容复制到新文件(第二个参数%2%)。它可以像下面的声明一样简单:
copy %1% %2%
现在,如果用户以相反的顺序传递上述参数,结果将远非理想(实际上非常错误)。
那么,用户是否有办法按名称传递参数:例如somebatchfile.bat "SOURC=originalFile.txt" "TARGET=newFile.txt"
以及脚本识别它们并在正确的位置使用' copy %SOURCE% %TARGET%
?
谢谢,

是的,你可以做类似的事情,虽然我不认为你可以使用“=”作为标记分隔符。您可以使用冒号“:”,somebatchfile.bat "SOURC:originalFile.txt" "TARGET:newFile.txt"
。以下是如何拆分令牌的示例:
@echo off
set foo=%1
echo input: %foo%
for /f "tokens=1,2 delims=:" %%a in ("%foo%") do set name=%%a & set val=%%b
echo name: %name%
echo value: %val%
运行它会产生这个:
C:\>test.bat SOURC:originalFile.txt
input: SOURC:originalFile.txt
name: SOURC
value: originalFile.txt
[编辑]
好吧,也许昨晚我睡觉的时间太近了,但今天早上又看了,你可以这样做:
@echo off
set %1
set %2
echo source: %SOURCE%
echo target: %TARGET%
哪会产生这个(请注意,我在命令行上反转了源和目标以显示它们已正确设置和检索):
C:\>test.bat "TARGET=newFile.txt" "SOURCE=originalFile.txt"
source: originalFile.txt
target: newFile.txt
请注意,在set
之前评估%1和%2,以便将它们设置为环境变量。但必须才能在命令行中引用。

派对有点迟了:)这是我对管理“posix like”选项的建议。
例如mybatchscript.bat -foo=foovalue -bar=barvalue -flag
:parseArgs
:: asks for the -foo argument and store the value in the variable FOO
call:getArgWithValue "-foo" "FOO" "%~1" "%~2" && shift && shift && goto :parseArgs
:: asks for the -bar argument and store the value in the variable BAR
call:getArgWithValue "-bar" "BAR" "%~1" "%~2" && shift && shift && goto :parseArgs
:: asks for the -flag argument. If exist set the variable FLAG to "TRUE"
call:getArgFlag "-flag" "FLAG" "%~1" && shift && goto :parseArgs
:: your code here ...
echo FOO: %FOO%
echo BAR: %BAR%
echo FLAG: %FLAG%
goto:eof
..这里是完成工作的功能。您应该将它们放在同一个批处理文件中
:: =====================================================================
:: This function sets a variable from a cli arg with value
:: 1 cli argument name
:: 2 variable name
:: 3 current Argument Name
:: 4 current Argument Value
:getArgWithValue
if "%~3"=="%~1" (
if "%~4"=="" (
REM unset the variable if value is not provided
set "%~2="
exit /B 1
)
set "%~2=%~4"
exit /B 0
)
exit /B 1
goto:eof
:: =====================================================================
:: This function sets a variable to value "TRUE" from a cli "flag" argument
:: 1 cli argument name
:: 2 variable name
:: 3 current Argument Name
:getArgFlag
if "%~3"=="%~1" (
set "%~2=TRUE"
exit /B 0
)
exit /B 1
goto:eof
将文件另存为mybatchscript.bat
并运行
mybatchscript.bat -bar=barvalue -foo=foovalue -flag
你会得到:
FOO: foovalue
BAR: barvalue
FLAG: TRUE

我非常喜欢的其他方式:
set c=defaultC
set s=defaultS
set u=defaultU
:initial
if "%1"=="" goto done
echo %1
set aux=%1
if "%aux:~0,1%"=="-" (
set nome=%aux:~1,250%
) else (
set "%nome%=%1"
set nome=
)
shift
goto initial
:done
echo %c%
echo %s%
echo %u%
运行以下命令:
arguments.bat -c users -u products
将生成以下输出:
users
defaultS
products

我想看到读取提供给批处理程序的命名参数的可能性。例如:
myBatch.bat arg1 arg2
读取参数可以按如下方式完成:
%~1 would be arg1
%~2 would be arg2
提供给批处理程序的上述参数很容易阅读,但是每次执行它时,都必须保持顺序并记住arg1应该具有的内容。为了克服它,参数可以作为键:值格式提供。命令如下所示:
mybatch.bar key1:value1 key2:value2
虽然没有直接的方法来解析这样的参数列表。我在批处理脚本中编写了以下嵌套for循环,它基本上将解析并创建环境变量,其中key1作为名称,并为其赋值value1。通过这种方式,您可以使用直接读取环境变量的方式读取所有提供的参数。
@echo off
FOR %%A IN (%*) DO (
FOR /f "tokens=1,2 delims=:" %%G IN ("%%A") DO setLocal %%G=%%H
)
之后,您可以使用%key1%
格式来读取所提供的所有参数。

一个非常老的问题,但是我认为我找到了一种将key=value
参数传递到批处理文件的巧妙方法(没有外部依赖项)。您可以使用以下MWE测试该方法:
@echo off
chcp 65001
rem name this file test.bat and call it with something like:
rem test keyc=foo keyd=bar whatever keya=123 keyf=zzz
setlocal enabledelayedexpansion
set "map=%*"
call :gettoken keya var1
call :gettoken keyb var2
call :gettoken keyc var3
rem replace the following block with your real batch
rem ************************************************
echo:
echo Map is "%map%"
echo Variable var1 is "%var1%"
echo Variable var2 is "%var2%"
echo Variable var3 is "%var3%"
echo:
echo Done.
echo:
pause
rem ************************************************
goto :eof
:gettoken
call set "tmpvar=%%map:*%1=%%"
if "%tmpvar%"=="%map%" (set "%~2=") else (
for /f "tokens=1 delims= " %%a in ("%tmpvar%") do set tmpvar=%%a
set "%~2=!tmpvar:~1!"
)
exit /b
方法相当:
key=value
参数可以与其他参数(例如文件名)混合使用,并且因为用于存储值的变量的名称与键的名称无关null
或{{1} },而不是空的享受。

我认为您在Windows批处理脚本中寻找getopt类型的支持,遗憾的是它并不完整。你可能得到的最接近的是使用GetOpt.btm script。通过这个,您可以使用命令执行脚本:
somebatchfile.bat /SOURC:originalFile.txt /TARGET:newFile.txt
代码:
@echo off
:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
:: GetOpt - Process command line options
::
:: Michael Fross
:: [email]michael@fross.org[/email]
:: [url]http://fross.org[/url]
::
:: This program scans the command line sent to it and sets various
:: environment variables that coorespond to the settings.
::
:: It sets an OPTION_arg variable for each arg on the command line.
:: If a switch, the env var is set to 1. If a value is given via the colon sign,
:: it's set to that value. Note, there can not be any white space around the ':'
::
:: Use "If defined OPTION_arg" or "If %OPTION_arg eq value" to test for options
::
:: It also sets a parameter variable for each paramater entered: PARAM_1 to PARAM_n
:: PARAM_0 is a special value that contains the number of PARAMs. Useful for looping
:: through all of them. For example, do i = 1 to %PARAM_0 by 1 ...
::
:: In your batch file call getopt as:
:: call GetOpt.btm %$
::
:: I also recommend setting setlocal and endlocal in the host batch file so that
:: the option / param variable do not stick around after the host batch files exits.
::
:: Example usage: BatchFile.btm /a /b:22 /longopt Parm1 Parm2 /quotedArg:"long quoted arg"
:: OPTION_a will equal 1.
:: OPTION_b will equal 22
:: OPTION_quotedArg will equal "long quoted arg"
:: OPTION_longopt will eqal 1.
:: PARAM_1 will equal Parm1
:: PARAM_2 will equal Parm2
:: PARAM_0 will be set to the number of parms, so 2 in this case
::
:: To get debug messages, set DEBUG=1. This will give detailed information for each
:: parameter on the command line as getopt loops through the list.
::

进行此尝试(纯批处理):
set PARAM_0=0
:parameters_parse
set parameter=%~1
if "%parameter%"=="" goto parameters_parse_done
if "%parameter:~0,1%"=="-" (
set ARG_%parameter:~1%="%~2"
shift
shift
goto parameters_parse
)
if "%parameter:~0,1%"=="/" (
set ARG_%parameter:~1%="%~2"
shift
shift
goto parameters_parse
)
set /a PARAM_0=%PARAM_0%+1
set PARAM_%PARAM_0%="%~1"
shift
goto parameters_parse
:parameters_parse_done
rem Insert your script here
和一些测试:
call args.bat /bar="Hello World" Test1 -baz "Test test test" /foo=Test1 Test2
echo foo=%ARG_foo%
echo bar=%ARG_bar%
echo baz=%ARG_baz%
echo count=%PARAM_0%
echo 1=%PARAM_1%
echo 2=%PARAM_2%
输出:
foo="Test1"
bar="Hello World"
baz="Test test test"
count=2
1="Test1"
2="Test2"

OP 的 CMD
参数都采用 "[VarName]=[Something]"
形式
FOR %%_ IN (%*) DO SET "%%~_"
或者更好看的代码
FOR %%_ IN (%*) DO SET "%%~_"
也就是说,这里有一个更完整的脚本示例,您可以将所有脚本放在 :Main
函数中
@( Setlocal
ECHO OFF
FOR %%_ IN (%*) DO SET "%%~_"
)
CALL :Main
( ENDLOCAL
EXIT /B )
