Or do you mean something more like this?

sed -e h -e 's/[^,]*,\([^,]*\),[^,]*/\1/p' -e g -e 's/,[^,]*,/,/'

Or using awk:

awk -F, '{print $1,$3}' < infile > outfile

I would do a

cat infile | cut -d, -f1,3 | tr " " "\012" >outfile

which should filter out the first and third column separated by
commas and separate them afterwards by a newline...
