Heh ...its works. Why I didnt check earlier this package ? ;/

Many thanks for help ! Smilie

Best regards,
Paweł

Edit:

In your solution there is "getline" command. In my case I am using this script against large file (more then 90k records) and on output I see:
Code:
"gawk: (FILENAME=file.csv FNR=6477) fatal: cannot open pipe".

Somewhere should be function "close" ? (source http://www.gnu.org/software/gawk/manual/html_node/Close-Files-And-Pipes.html ). If I understand correctly getline open file one time and keep it in cache ;/

Do you know how to avoid this problem ?
