【问题描述】：

这是一个输入文件：

some data1 blah blah blah
some data2 blah blah bllah blah
Result HEX: 1ABC
Name......: Some name 1
-------------------------------------------
some random data1 blah blah blah bl
some random data2 blah blah bl
some random data3 blah blah blah blah bla
some random data4 blah blah blah bla
Result HEX: 2BCD
Name......: Whatever name 2
-------------------------------------------
some random data1 blah blah blah blah
some random data2 blah blah blah blah blah
some random data3 blah blah blah bl
Result HEX: 3CDE
Name......: Some name 3
-------------------------------------------

我需要做到这一点：

some data1 blah blah blah
some data2 blah blah bllah blah
Result HEX: 1ABC
Result DEC: 6844
Name......: Some name 1
-------------------------------------------
some random data1 blah blah blah bl
some random data2 blah blah bl
some random data3 blah blah blah blah bla
some random data4 blah blah blah bla
Result HEX: 2BCD
Result DEC: 11213
Name......: Whatever name 2
-------------------------------------------
some random data1 blah blah blah blah
some random data2 blah blah blah blah blah
some random data3 blah blah blah bl
Result HEX: 3CDE
Result DEC: 15582
Name......: Some name 3
-------------------------------------------

因此，在文件中匹配“Result HEX:”的每一行之后，我必须在新行后面附加一个“Result DEC:”，并将计算得到的十六进制值转换为十进制。我有一些小型嵌入式 linux（基于 busybox），所以我发现我可以使用以下命令转换 hex2dec：

# printf "%d\n" 0x1ABC
6844

有人可以帮忙吗？...这对我来说太大了:( 谢谢！

gawk 来救援！

$ gawk --non-decimal-data '1; /HEX/{printf "%s DEC: %d\n", $1,"0x"$3}' file

some data1 blah blah blah
some data2 blah blah bllah blah
Result HEX: 1ABC
Result DEC: 6844
Name......: Some name 1
-------------------------------------------
some random data1 blah blah blah bl
some random data2 blah blah bl
some random data3 blah blah blah blah bla
some random data4 blah blah blah bla
Result HEX: 2BCD
Result DEC: 11213
Name......: Whatever name 2
-------------------------------------------
some random data1 blah blah blah blah
some random data2 blah blah blah blah blah
some random data3 blah blah blah bl
Result HEX: 3CDE
Result DEC: 15582
Name......: Some name 3
-------------------------------------------

您可以通过将模式替换为$2=="HEX" 来微调匹配
