私のコードを確認するときは、ここにあるドキュメントを使用して起動スクリプトを作成してください。https://www.shellcheck.net無視するように警告します。しかし、コードを書いて、可能であればその警告を避けるより良い方法があるかどうか疑問に思います。

わかりました、尋ねるように最初にウェブサイトで知らせるように正確に行うと得られます。

@roaimaが提案したように、この時点であなたは${name}
内部ブロックを持つ'EOF'
行について非常に疑わしいでしょう。name="${name}"
生成されたファイルの先頭にファイルがあるので、エスケープできます。この時点で、スクリプトをこのように変更して${name}_start
プログラムの構文が正しいことを確認し、他の関数名を実際の名前に変更しますが、他の変数は実行時まで拡張されていません。
