I know there are lots of questions about it but i cantI can't get it working.

I want to clean a group (for instance rootroot) in /etc/group/etc/group with sedsed or awkawk. So iI need to delete everything after "root:*:0:"root:*:0:

I tried to remove it with:

cat /etc/group | awk '!p;/^root:*:0:/{p=1}'

cat /etc/group | awk '!p;/^root:*:0:/{p=1}' and

cat /etc/group | sed 's/root\:\*\:0\:.*//'

cat /etc/group | sed 's/root\:\*\:0\:.*//'

but sed removes the whole root line.

What am i doing wrong?
