I have file "report.csv" . This report is generated based on few parameters
which can range from 1-10. So the report.csv has all the parameters printed in
it first and then , the main header and the data. Now I need to process
this file with the header and data and exclude all the parameters. The file looks like this



para_1: abc

para_2: def

para_3: ghi

.

.

.

para_n: xyz



Customer_Name, Customer_Number, .....

Jon Doe,19923

Adam Plak,19985

.

.

.

.

.



so on.



I used below command to get the position of the Column header



This gives me the position

grep -n "Customer_Name" report.csv | cut -d : -f1

(let's say) 13

Then I use this command to copy to another file and use the new file

sed '1,13d' report.csv >> report_test.csv



however i need to make it dynamic , like



$var1 = grep -n "Customer_Name" report.csv | cut -d : -f1

$var2 = d

sed '1,$var1$var2' report.csv >> report_test.csv



can you experts please help achieve this in Shell Script ?
