Question

当我有一个类似下面的USB主机列表时，我想根据制造商过滤掉特定的块：然后获取块的UUID。我可以使用哪些命令？

Answer 1

假设UUID始终是每个块的第一行：

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

当然，将“Logitech”更改为您想要的任何制造商。

Answer 2

我认为最简单的方法是使用像AWK或Perl这样的语言。使用Perl：

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

shell命令捕获特定块中的行
