sed从dos文本文件中提取数据转换为csv

标签： sed multiline

出于报告原因，我需要从几个cpuz报告中提取RAM信息并将它们放入csv中。 下面是一个示例文本文件（剪切），其中包含我要提取的文本。

我想提取以DIMM开头的行之后的所有文本，但只提取下一行以制表符和SMBus地址开始，然后降至标称电压。然后我想把它们分成几列（虽然我只关心类型，大小和最大带宽）

生成的csv将具有以下列（在此示例中为2行）

计算机名称（来自文件名），Dimm＃，smbus地址，内存类型，制造商等。

然而，我在第一个提取阶段堕落了。我正在使用sed，但是在这个多线命令上摔倒了：

sed -n -e'N; / DIMM＃\ t * [0-9] \ r \ n \ t /，/ Nominal / p'cpuz-FHD505.txt

出于某种原因，它只能拾取DIMM＃2块。

我应该用什么sed语句给我两个dimm块直到包括标称电压在内？

老实说，我可能会放弃并在python中写这个，因为我比较熟悉，但我很想知道我在这个多线sed语句中搞砸了。

cpuz输出： -
