歡迎StackOverflow上。你有沒有試圖自己弄清楚這一點？如果沒有，你至少應該嘗試一下。如果有，請[編輯]你的問題，並告訴我們你已經嘗試了什麼，以何種方式，它不工作對你解釋。 –

我認爲最簡單的方法是使用像AWK或Perl這樣的語言。用Perl：

perl -nwe ' BEGIN { $/ = "" } 
      next unless m/^Manufacturer: +THIS$/m; 
      print "$1\n" if m/^UUID: +([0-9a-f-]+)$/m; 
      ' <input_file> output_file

假設UUID始終是每個塊的第一行：

awk 'BEGIN{RS="\n\n";FS="\n"}/Manufacturer: *Logitech/{print $1}' test.in

當然，改變「羅技」你要哪個製造商。
