sed 从dos文本文件中提取数据转换为csv答案

【问题标题】：sed extract data from dos text file convert to csvsed 从dos文本文件中提取数据转换为csv

【问题描述】：

出于报告原因，我需要从多个 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（截断），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，但仅提取下一行以制表符和 SMBus 地址开头的地方，并下降到标称电压。然后我想将它们分成几列（尽管我只关心类型、大小和最大带宽）

生成的 csv 将具有以下列（在本例中为 2 行）

计算机名称（来自文件名）、Dimm #、smbus 地址、内存类型、制造商等

但是我在第一个提取阶段就摔倒了。我正在使用 sed，但在这个多行命令中摔倒了：

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

由于某种原因，它只拾取 DIMM #2 块。

我应该使用什么 sed 语句来只给我两个调光块直到包括标称电压在内的线路？

说实话，我可能会放弃并用 python 写这个，因为我更熟悉，但我很想知道我在哪里搞砸了这个多行 sed 语句。

cpuz 输出：-

标签： sed multiline

【解决方案1】：

 awk -vRS="" -F"\n" '/DIMM/&&$2~/SMBus/{ 
   for(i=1;i<=NF;i++) {
     print $i
     # from here, you process the columns you need
   }       
 }' file

【讨论】：

嗨，这是否根据行作为列来查看文件，然后如果一行包含文本 DIMM，然后第二行包含 SMBus，它将返回以下行，直到标称电压?我看不到脚本如何知道何时停止并移至 DIMM 2。当我在文件上运行它时（例如上面的 cpuz 输出），我什么也没有返回。

【解决方案2】：

试试这个：

sed -n ':a; /^DIMM/,/^[[:blank:]]*Nominal Voltage/ N; /^DIMM/,/[[:blank:]]*Nominal Voltage/ ! d ;/[[:blank:]]*Nominal Voltage/ {/[[:blank:]]*Nominal Voltage/p;d}; ba' cpuz-FHD505.txt
