Concatenate csv files with same header

Post date: Mar 21, 2015 12:02:55 AM

I want to merge csv files into one single file by preserving the header of the first one.

> cat file1.csv

Id,city,name ,location

1,NA,JACK,CA

> cat file2.csv

ID,city,name,location

2,NY,JERRY,NY

> cat file3.csv

ID,city,name,location

3,WA,BERNY,WA

> awk 'FNR==1 && NR!=1{next;}{print}' file*.csv > file123.csv

> cat file123.csv

Id,city,name ,location

1,NA,JACK,CA

2,NY,JERRY,NY

3,WA,BERNY,WA
