スイッチに SSH で接続し、フラッシュ内の特定のソフトウェア セットを探して削除できるようにするスクリプトを作成しようとしています。結果「A」が表示された場合はアクション「B」を実行し、結果「C」が表示された場合はアクション「B」を実行します。1 つのコマンドを実行すると、これらすべての結果が表示されます。
これは、私が期待している結果の例です。

私が探しているのは、「flash1:」ディレクトリです。現在、合計 9 つのフラッシュ ファイル システムである可能性があります。常に「flash1:」があります。私がやりたいことは、考えられる各ディレクトリに移動し、ファイルまたはディレクトリ全体を削除することです。そして、それらが他のディレクトリでない場合は、先に進みます。
私が知りたいのは、exp_continue を適切に使用する方法、またはこのインスタンスで使用する必要があるかどうかです。これは私が書いたもので、ソフトウェアをフラッシュ1にコピーしますが、flas2などが存在する場合、ソフトウェアを他のフラッシュにコピーまたは削除しません。
