Linux 命令行编辑.CSV文件

我有一个.CSV文件，其中的行具有相同的ID

下面是一个.CSV文件示例：

Alias,Date,Volume,Type,Type2,MSI
ID1,20170418,0.516006112,CHART,GAS,10-10-10-1
ID2,20170418,4.03900528,CHART,GAS,10-10-10-2
ID2,20170418,0.399999887,METER,OIL,10-10-10-2
ID2,20170418,0,METER,CONDY,10-10-10-2
ID3,20170418,0.399999887,CHART,GAS,10-10-10-3
ID4,20170418,6.599591255,CHART,GAS,10-10-10-4
ID5,20170418,4.6501894,CHART,GAS,10-10-10-5
ID6,20170418,1.831178546,CHART,GAS,10-10-10-6
ID6,20170418,0.190000013,METER,OIL,10-10-10-6
ID6,20170418,0,METER,CONDY,10-10-10-6

我需要创建一个Linux脚本来编辑这个.CSV文件，如下所示：

Alias,Date,Volume,Type,Type2,MSI,Volume Oil, Volume Condy
ID1,20170418,0.516006112,CHART,GAS,10-10-10-1,,
ID2,20170418,4.03900528,CHART,GAS,10-10-10-2,0.399999887,0
ID3,20170418,0.399999887,CHART,GAS,10-10-10-3,,
ID4,20170418,6.599591255,CHART,GAS,10-10-10-4,,
ID5,20170418,4.6501894,CHART,GAS,10-10-10-5,,
ID6,20170418,1.831178546,CHART,GAS,10-10-10-6,0.190000013,0

如果别名字段重复

并且行中有计量油：将体积移动到前一行中的“体积油”，删除此行

并且行具有仪表CONDY：将卷移动到前一行的“volume CONDY”，删除此行

awk方法（假设只有三条记录具有相同的

ID

）：

输出：

Alias,Date,Volume,Type,Type2,MSI,Volume Oil,Volume Condy
ID1,20170418,0.516006112,CHART,GAS,10-10-10-1,,
ID2,20170418,4.03900528,CHART,GAS,10-10-10-2,0.399999887,0
ID3,20170418,0.399999887,CHART,GAS,10-10-10-3,,
ID4,20170418,6.599591255,CHART,GAS,10-10-10-4,,
ID5,20170418,4.6501894,CHART,GAS,10-10-10-5,,
ID6,20170418,1.831178546,CHART,GAS,10-10-10-6,0.190000013,0

您自己尝试了什么？使用SED，我可以添加标题（第一行），这看起来很好，只是它忽略了米-康迪值0。@TrevorWelsh，抱歉，修复。现在好了，非常感谢！现在我只需要弄清楚这一切是如何运作的：）
