简单的解决方法(即使问题已经很老了)

Test1.bat

echo off
echo "Batch started"
set arg1=%1
echo "arg1 is %arg1%"
echo on
pause

CallTest1.bat

call "C:\Temp\Test1.bat" pass123

输出

YourLocalPath>call "C:\Temp\test.bat" pass123

YourLocalPath>echo off
"Batch started"
"arg1 is pass123"

YourLocalPath>pause
Press any key to continue . . .

其中YourLocalPath是当前目录路径。

为了简单起见，将命令参数存储在变量中，并使用变量进行比较。

它不仅写起来简单，而且维护起来也很简单，所以如果后来其他人或你在很长一段时间后阅读了你的脚本，它将很容易理解和维护。

内联编写代码:参见其他答案。

让我们保持简单。

下面是.cmd文件。

@echo off
rem this file is named echo_3params.cmd
echo %1
echo %2
echo %3
set v1=%1
set v2=%2
set v3=%3
echo v1 equals %v1%
echo v2 equals %v2%
echo v3 equals %v3%

下面是命令行中的3个调用。

C:\Users\joeco>echo_3params 1abc 2 def  3 ghi
1abc
2
def
v1 equals 1abc
v2 equals 2
v3 equals def

C:\Users\joeco>echo_3params 1abc "2 def"  "3 ghi"
1abc
"2 def"
"3 ghi"
v1 equals 1abc
v2 equals "2 def"
v3 equals "3 ghi"

C:\Users\joeco>echo_3params 1abc '2 def'  "3 ghi"
1abc
'2
def'
v1 equals 1abc
v2 equals '2
v3 equals def'

C:\Users\joeco>

最近有个朋友问我这个问题，所以我想在这里发布一下我如何在批处理文件中处理命令行参数。

正如您将看到的，这种技术有一些开销，但它使我的批处理文件非常容易理解和快速实现。以及支持以下结构:

>template.bat [-f] [--flag] [--namedvalue value] arg1 [arg2][arg3][...]

它的jist包含:init、:parse和:main函数。

示例使用

>template.bat /?
test v1.23
This is a sample batch file template,
providing command-line arguments and flags.

USAGE:
test.bat [flags] "required argument" "optional argument"

/?, --help           shows this help
/v, --version        shows the version
/e, --verbose        shows detailed output
-f, --flag value     specifies a named parameter value

>template.bat          <- throws missing argument error
(same as /?, plus..)
****                                   ****
****    MISSING "REQUIRED ARGUMENT"    ****
****                                   ****

>template.bat -v
1.23

>template.bat --version
test v1.23
This is a sample batch file template,
providing command-line arguments and flags.

>template.bat -e arg1
**** DEBUG IS ON
UnNamedArgument:    "arg1"
UnNamedOptionalArg: not provided
NamedFlag:          not provided

>template.bat --flag "my flag" arg1 arg2
UnNamedArgument:    "arg1"
UnNamedOptionalArg: "arg2"
NamedFlag:          "my flag"

>template.bat --verbose "argument #1" --flag "my flag" second
**** DEBUG IS ON
UnNamedArgument:    "argument #1"
UnNamedOptionalArg: "second"
NamedFlag:          "my flag"

创建一个新的批处理文件(例如:openclass.bat)，并在文件中写入这一行:

java %~n1

然后将批处理文件放在system32文件夹中，找到你的Java类文件，右键单击，Properties, Open with…，然后找到你的批处理文件，选择它，这就是…

这对我很管用。

PS:当我关闭Java类时，我找不到关闭cmd窗口的方法。现在……

我是这样做的:

@fake-command /u %1 /p %2

下面是命令的样子:

test.cmd admin P@55w0rd > test-log.txt

%1应用于第一个参数，%2(这是棘手的部分)应用于第二个参数。您最多可以通过这种方式传递9个参数。

成对的参数

如果你喜欢在键值对中传递参数，你可以使用这样的方法:

@echo off

setlocal enableDelayedExpansion

:::::  asigning arguments as a key-value pairs:::::::::::::
set counter=0
for %%# in (%*) do (    
    set /a counter=counter+1
    set /a even=counter%%2
    
    if !even! == 0 (
        echo setting !prev! to %%#
        set "!prev!=%%~#"
    )
    set "prev=%%~#"
)
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

:: showing the assignments
echo %one% %two% %three% %four% %five%

endlocal

举个例子:

c:>argumentsDemo.bat one 1 "two" 2 three 3 four 4 "five" 5
1 2 3 4 5

预定义的变量

您还可以提前设置一些环境变量。这可以通过在控制台或在我的电脑上设置来完成:

@echo off

if defined variable1 (
    echo %variable1%
)

if defined variable2 (
    echo %variable2%
)

像这样称呼它:

c:\>set variable1=1

c:\>set variable2=2

c:\>argumentsTest.bat
1
2

包含列出值的文件

您还可以指向预先设置所需值的文件。 如果这是脚本:

@echo off

setlocal
::::::::::
set "VALUES_FILE=E:\scripts\values.txt"
:::::::::::


for /f "usebackq eol=: tokens=* delims=" %%# in ("%VALUES_FILE%") do set "%%#"

echo %key1% %key2% %some_other_key%

endlocal

values文件是这样的:

:::: use EOL=: in the FOR loop to use it as a comment

key1=value1

key2=value2

:::: do not left spaces arround the =
:::: or at the begining of the line

some_other_key=something else

and_one_more=more

调用它的输出将是:

Value1 value2别的东西

当然，您可以结合所有方法。检查参数语法，shift
