[squid-users] Script Help

I know this is not directly related to Squid but hoping someone could
help me with this script. The script is a check to see if (Squid) http
and https are both working and if not then change the iptables to route
the traffic to the backend server. Also wondering if anyone knows of a
better way of doing this?

#!/bin/sh
while [ 1 ]; do
    TEST_SQUID=`netstat -a | grep -c https
    if [ "$TEST_SQUID" -gt 0 ]; then
        iptables -t nat -A PREROUTING -p tcp -i eth0 -d x.x.102.125
--dport 80 -j LOG
        iptables -A FORWARD -p tcp -i eth0 -d x.x.102.122 --dport 80 -j
LOG
        iptables -A FORWARD -p tcp -i eth0 -d x.x.102.122 --dport 80 -j
ACCEPT
        iptables -t nat -A PREROUTING -p tcp -i eth0 -d x.x.102.125
--dport 80 -j DNAT --to x.x.102.122:80
        iptables -A FORWARD -p tcp -i eth0 -d x.x.102.122 --dport 80 -j
ACCEPT
        iptables -t nat -A POSTROUTING -o eth0 -p tcp -d x.x.102.122
--dport 80 -j SNAT --to x.x.102.125
    fi

    TEST_SQUID=`netstat -a | grep -c :http
    if [ "$TEST_SQUID" -gt 0 ]; then
        iptables -t nat -A PREROUTING -p tcp -i eth0 -d x.x.102.125
--dport 80 -j LOG
        iptables -A FORWARD -p tcp -i eth0 -d x.x.102.122 --dport 80 -j
LOG
        iptables -A FORWARD -p tcp -i eth0 -d x.x.102.122 --dport 80 -j
ACCEPT
        iptables -t nat -A PREROUTING -p tcp -i eth0 -d x.x.102.125
--dport 80 -j DNAT --to x.x.102.122:80
        iptables -A FORWARD -p tcp -i eth0 -d x.x.102.122 --dport 80 -j
ACCEPT
        iptables -t nat -A POSTROUTING -o eth0 -p tcp -d x.x.102.122
--dport 80 -j SNAT --to x.x.102.125
    fi
    sleep 60
done

The error I get is:

./squid_backup: line 2: [: : integer expression expected
./squid_backup: line 13: -a: command not found
0
./squid_backup: line 14: [: : integer expression expected

Any help would be great.
