How to add heater to the hts-count output file in linux?

[wmseq]

Hi every one,
I have htseq-count file as follows:

GB40001-RA 2 2 0 2 2 4
GB40002-RA 0 0 1 0 0 0
GB40003-RA 3 3 1 1 0 5
GB40004-RA 1 0 0 0 0 0

I'd like to add header to it to get following one in linux:

ID CK1 CK2 CK3 CA1 CA2 CA3
GB40001-RA 2 2 0 2 2 4
GB40002-RA 0 0 1 0 0 0
GB40003-RA 3 3 1 1 0 5
GB40004-RA 1 0 0 0 0 0

Is there anyone who know how to do it?

Thanks a lot!!

that's easy

echo -e "ID\tCK1\tCK2\t..." > file_with_header.count 
cat file.count >> file_with_header.count

\t means tab

use spaces "ID CK1 CK2 ..." if you have only spaces between columns...

Thanks a lot, deitmar13!
It works, but a '\t' should be added before 'ID'.
