More awk questions

| Hi again,
I have a file with a bunch of usernames in a single line per group (/var/etc/group) - I want to
extract each group to another file in columnar format. This is what I got so far:
cat group | grep group1 > group1.file
awk '{FS=","};{print $1}' group1.file
Awk gives me the first username but not the subsequent ones...I think I need a variable defined, but
I don't know how to pass it to awk.
Any sugesstions?
TIA, Ben
p.s. group1.file is comma delimited

The file is formatted like this...?
group1,abc,def,ghi
group2,jkl,mno,pqr
Then try...
awk -F, 'BEGIN{OFS="\n"} /group1/{$1=$1;print}' /var/etc/group
