awk

Hi,

Code:
awk 'BEGIN{FS="|";ORS="";}{if($1 ~ /^00/ && NR != 1){print "\n"$0;}else{print $0;}}' file
 
Here FS is input field separator. It will split the input line based on separator and store the columns in $1,$2 and so on.
 
ORS is an Output Record separator. By default ORS="\n". If you use print function, that will append ORS. 
so i dont want to append "\n" since i have to append more than one line.
 
As you know $1 is a first column and i am checking that $1 starts with 00 then 
i am creating a new line and i am printing that current line($0 has whole line).
 
In if condition, i have included one more condition that NR != 1. NR give you the line number. 
Here i dont want to create new line for the first line.

Cheers,
RangaSmilie
