Hi,

Try this one,

Code:
awk 'BEGIN{FS=",";ORS="";}{if(p!=$1 && NR != 1){print "\n"$0;}else{print;}p=$1;}END{print "\n";}' file

What Operating System and version do you have and what Shell do you use?

What have you tried so far?

What is the real-world purpose of the script? The comma-delimited structure is broken in the output file.
