[batch-file] 배치 파일에 인수를 전달하려면 어떻게해야합니까?

친구가 최근 에이 주제에 대해 묻고 있었기 때문에 배치 파일에서 명령 줄 인수를 처리하는 방법을 게시한다고 생각했습니다.

이 기술에는 약간의 오버 헤드가 있지만 배치 파일을 이해하기 쉽고 빠르게 구현할 수 있습니다. 다음 구조를 지원할뿐 아니라

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

그것의 JIST가 구비되고 :init, :parse그리고 :main기능.

사용법 예

>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"
