linux - シェルスクリプトの問題

Question

開発したアプリケーションを Linux でサービスとして実行するためのシェル スクリプトを作成しています。私が書いたシェル スクリプトは、 . /smpp-daemon.sh startを使用すると完全に機能します。ただし、次の構文を使用したい場合: sh smpp-daemon.sh start次のエラーが発生しました:/srv/smpp/bin/smpp-daemon.sh: 26: /srv/smpp/bin/smpp-daemon.sh : 関数: 見つかりません /srv/smpp/bin/smpp-daemon.sh: 27: ローカル: 関数内にありません。

これはシェルスクリプトです：
