您好，我目前有一个csv文件。我想为所有记录添加一个名为budget和values为True的新标题字段。这是我的csv文件。
id,address1,address2,address3,address4,addressprofile,administrator,averageclickthroughrate,contactnumber,contractid,country,createdby,createdon,currency,customercontactnumber,customerid,defaultlanguage,features,internal,inventories,lastupdated,lastupdatedby,logo,name,status,testmessagecontactlist,testmessagelimit,usedefaultclickthroughrate,zipcode

这是我期望的以下结果。
id,address1,address2,address3,address4,addressprofile,administrator,averageclickthroughrate,budget,contactnumber,contractid,country,createdby,createdon,currency,customercontactnumber,customerid,defaultlanguage,features,internal,inventories,lastupdated,lastupdatedby,logo,name,status,testmessagecontactlist,testmessagelimit,usedefaultclickthroughrate,zipcode

答案 0 :(得分：0)
awk可以轻松完成这项工作，类似于@kvantour链接：
awk 'BEGIN{FS = OFS = ","} {$8 = $8 FS (NR == 1 ? "budget" : "true")}1'
其中FS：字段分隔符，OFS：输出字段分隔符，NR：当前行号
