窗户BAT文件可选参数解析 [英] Windows Bat file optional argument parsing

问题描述

我需要我的bat文件接受多个可选的命名参数。

I need my bat file to accept multiple optional named arguments.

mycmd.bat man1 man2 -username alice -otheroption

例如我的命令有2强制性参数和两个可选参数（-username），有爱丽丝的参数值，-otheroption：

For example my command has 2 mandatory parameters, and two optional parameters (-username) that has an argument value of alice, and -otheroption:

我希望能够将这些值采摘到变量。

I'd like to be able to pluck these values into variables.

只是把到任何一个电话一个已经解决了这个。曼这些蝙蝠文件是一种痛苦。

Just putting out a call to anyone that has already solved this. Man these bat files are a pain.

推荐答案

虽然我倾向于@AlekDavis同意，是否仍有几种方法在NT外壳做到这一点。

Though I tend to agree with @AlekDavis, there are nonetheless several ways to do this in the NT shell.

我想借此 SHIFT 命令的方法和的IF 条件分支，这样的事情...

The approach I would take advantage of the SHIFT command and IF conditional branching, something like this...

@ECHO OFF

SET man1=%1
SET man2=%2
SHIFT & SHIFT

:loop
IF NOT "%1"=="" (
    IF "%1"=="-username" (
        SET user=%2
        SHIFT
    )
    IF "%1"=="-otheroption" (
        SET other=%2
        SHIFT
    )
    SHIFT
    GOTO :loop
)

ECHO Man1 = %man1%
ECHO Man2 = %man2%
ECHO Username = %user%
ECHO Other option = %other%

REM ...do stuff here...

:theend
