A bit ugly, but this should do the trick in bash:

#!/bin/bash

[[ -n "$1" ]] || { echo "Tests NTP server for pending leap second insertion."; echo "Usage: $0 <server>"; exit ; }

LOCAL=`ntpq -c rv $n | sed 's/, /\n/g' | grep "leap="`
case $LOCAL in
        "leap=01"*) echo -e "\tWARNING: Pending leap found on: $1" ;;
        "leap=10"*) echo -e "\tWARNING: Pending leap found on: $1" ;;
        *) echo -e "\tPending leap not foud on: $1"; exit ;;
esac

echo "Testing Upstream Servers:"

for n in `ntpq -c assoc $1 | tail -n+4 | awk '{print $2}'`; do {
        ASSOC=`ntpq -c "rv $n" $1 | sed 's/, /\n/g' | grep leap`
        case $ASSOC in
                "leap=01"*) echo -e "\tWARNING: Pending leap second found on associated server: $n" ;;
                "leap=10"*) echo -e "\tWARNING: Pending leap found on associated server: $n" ;;
                *) echo -e "\tPending leap not foud on assicated server: $n" ;;
        esac
}
done
