Unix:merge multiple CSV files with same header by keeping the header of the first file

Question

I have to merge multiple CSV files with same headers. I have to keep the header of the first file and remove headers of all the other files and merge them and create one mas

Answer 1

If Perl is an option:

perl -ne 'print if $. > 1 or ! $h; $h=1; close ARGV if eof' *.csv > master.csv

$. is the line number.
It is NOT reset automatically between files, so close ARGV if eof is needed.
$h records if the header has already been printed.
