In installing the Cnews system under Microport V/AT, I have found that
the inews shell script breaks somewhere using egrep to locate the
groups to post to.

I found that Cnews comes with the utility gngp which seems to be a
perfect replacement for what was supposed to happen with egrep.

Below is the excerpt from inews which details the changes I made.

----

# Microport V/AT patch, egrep is broken so the gngp utility provided
# with cnews has been used instead. This should not break any other
# machines where gngp runs.

# look up groups in active, to determine disposition of this message.
# n, x and (unapproved) m flags are dealt with on the spot; if none are
# seen, the article is posted normally.
# escape egrep metacharacters.  In theory one could add " ' ` \ to the list.
#egreppat="^(` sed -e 's/[.+*()|[]/\\\\&/g' -e 's/,/|/g' <$nglist `) "
#egrep "$egreppat" $NEWSCTL/active >/dev/null || {
gngp -a `cat $nglist` $NEWSCTL/active >/dev/null || {
	echo "$0: `cat $nglist` matches no groups in $NEWSCTL/active" >&2
	exit 1
}
rm -f $grpok
#egrep "$egreppat" $NEWSCTL/active |
gngp -a `cat $nglist` $NEWSCTL/active |
	(while read ng high low flag junk	# look at next group's active entry
	do
		>>$grpok
		case "$flag" in
