この問題を解決するのに役立ちますか？

または

この情報を取得するより良い方法を知っていますか？

答え1

これにより、探しているフィールドに一致するすべての行が印刷されます。

awk '/Device ID|IP address|Interface|Port ID/ { print }' /path/to/input

grepsedおよび他の同様のツールを使用して同じことを実行できます。

少し良くなるかもしれません。

grep -Eo '(Device ID|IP address|Interface|Port ID): [^ ]+' /path/to/input

答え2

awkの代わりにegrepを使用するオプションはありますか？

egrep "Device|IP\ address|Interface|Port\ ID" input-file.txt

答え3

GB単位のログファイルでない場合

 perl -0ne 'for( /Device ID.*?Port ID.*?\n/sg ){ print "-"x 20,"\n$_\n"}' file

答え1
