Get web pages and compare

Hello

I'm writing a script to get content of web pages on different machines and compare them using their md5 hash

hear is my code


#!/bin/bash

# Cluster 1
CLUSTER1_SERVERS="srv01:7051 srv02:7052 srv03:7053 srv04:7054"
CLUSTER1_APPLIS="test/version.html test2/version.html test3/version.jsp test4/version.html test5/version.jsp"

# Cluster 2
CLUSTER2_SERVERS="srv01:7055 srv02:7056 srv03:7057 srv04:7058"
CLUSTER2_APPLIS="test/version.html test2/version.html test3/version.jsp test4/version.html"

# Cluster 4
CLUSTER4_SERVERS="srv01:7063 srv02:7064 srv03:7065 srv04:7066"
CLUSTER4_APPLIS="test/version.html test2/version.html"

# Liste des clusters ?* tester
CLUSTERS="CLUSTER1 CLUSTER2 CLUSTER4"

# init vars
CRITICAL=2
WARNING=1
OK=0

for cluster in $CLUSTERS
do
for server in $(eval echo \$${cluster}_SERVERS)
do
server_name=`echo $server | cut -d':' -f1,1`
server_port=`echo $server | cut -d':' -f2,2`
for applis in $(eval echo \$${cluster}_APPLIS)
do
checksum=`curl --silent --write-out '%{http_code}\n' "http://$server_name:$server_port/$applis" | md5sum`
if [[ ( "$checksum" -ne "$checksum1" ) ]]
then
exit_code=2
else
exit_code=0
fi
done
done
done

case $exit_code in
"2")
echo "CRITICAL - App Version Mismatch"
exit $CRITICAL
;;
"0")
echo "OK - All apps deployed are identical"
exit $OK
;;
*)
echo "CRITICAL - there's something wrong with this script ..."
exit $CRITICAL
;;
esac


getting web pages content and generation md5 hash works perfectly

but I'm a blocked when comparing them


if [[ ( "$checksum" -ne "$checksum" ) ]]


can someone guide me how i could accomplish this

thanks in advance

For string comparison don't use -ne use != instead.
