This is something Fred Blonder wrote a while back and passed around. It
does come in handy, especially if you are short on disk space and trying to
figure out what groups to shorten...


#! /bin/sh

# @(#)subscribers.sh	(University of Maryland) Fred Blonder 19-Aug-1983
#
# Find out how many people subscribe to each newsgroup

sub_tmp=/tmp/#s.$$

trap "rm -f $sub_tmp" 0 1 2 15

for dir in `awk -F: '{ print $6 }' /etc/passwd | sort -u`
do	# locate all login directories
	if	# if .newsrc exists
		[ -r $dir/.newsrc ]
	then	# find all newsgroups subscribed to, append to $sub_tmp
		awk -F: '/^net\..*: [0-9].*$/ { print $1 }' \
			$dir/.newsrc >> $sub_tmp
	fi
done

# Count all ocurrences of all newsgroups.
# Print result sorted by decreasing number of subscribers.
awk '{ x[$1] = x[$1] + 1 } \
	END { for (i in x) print i " " x[i] }' $sub_tmp | sort +1 -rn
