別の変数から最初の変数を抽出する

ホスト名のリストに対していくつかのping、nslookup、およびその他のコマンドを実行する.batスクリプトがあります。行のどこかで、リモートマシンのfqdnをエコー出力する変数％FQDN％を取得しますが、使用する元のホスト名と比較するには、％FQDN％変数のホスト名のみが必要です。

list.txtというファイルにホスト名のリストを入れました。（pc1、pc2、pc3）すべて新しい行に。そのホスト名は％1で、％FQDN％変数のホスト名=であるかどうかを確認する必要がありますか？

これをどのように達成するかについての提案はありますか？

私は漠然と、qbackについて何かコマンドやこれを行うことができるコマンドがあったことを覚えていますが、どのように使用するべきかわかりません。

ping、dnslookupなどを実行するメインスクリプトは次のようになります。すべてが正常に機能することを確認できたら、エコーの多くは後の段階で削除されます。

@cls

そして、list.txtには次のようなホスト名が含まれています。

DT048035
DT040676

％FQDN％のサンプル

DT048035.za.lacer.net

最初の部分が最初の前かどうかだけ確認したい。他のホスト名変数％1または％strSvr％（DT048035のみ）と同じです

これは動作するはずです
