何も繰り返すことなくテスト実行オプションを作成する正しい方法は何ですか？

リモートサーバーからファイルを検索してローカルコンピュータに戻すスクリプトを作成しています。まず、ツアーを実行してどの文書をインポートする必要があるかを知ることができたらよかったでしょう。

私は現在私が見つけたいくつかのコードのミックスインとgetopts出力リダイレクトを使用しています。ここ。

私の研究では、ZSHまたはBash関数から配列を返すことは非現実的です。このため、繰り返さずにこのスクリプトを書く方法を理解することは困難です。

これは私の現在のスクリプトです。

編集する：いくつかのbashismをzshと混ぜたことを許してください。私はzshを使ってこのスクリプトを書き始めましたが、#!/bin/bash後でzshに切り替えました。

# Establish -n flag means to do a dry run.
while getopts "ny:" flag; do
    case "$flag" in
        n) dry_run=1 ;;
        y) yesterday=${OPTARG} ;;
        *) echo 'error in command line parsing' >&2
           exit 1
    esac
done
shift $(($OPTIND-1))

# This is the folder I'm interested in getting files from
folder=${1:?"You must define a folder of interest"}

# Check to see if dry-run, if not proceed with copying the files over. 
if [ "$dry_run" -eq 1 ]; then
    print -Pn "\n%S%11F%{Initiating Dry-Run%}%s%f"

    # SSH onto server and find the most recently updated folder.
    # Then place that newest folder and folder of interest into the absolute file path.
    # Then SSH again and use find with that file-path
    # Return array of file paths

        fi
    done
    printf "${YELLOW}Bison Remote Fetch Complete!${NC}\n"
fi

ご覧のとおり、すべてのデータが最初のifステートメントの状況に閉じ込められているため、練習を実行したくない場合は、すべてのコードを再実行する必要があります。 bash / zshは実際に配列を返さないので、このコードをどのようにリファクタリングできますか？
