Linux Get web pages and compare
Hello,

I'm writing a shell script to wget content web pages from multiple server into a variable and compare

if they match return 0 or return 2


#!/bin/bash

# Cluster 1
CLUSTER1_SERVERS="srv1 srv2 srv3 srv4"
CLUSTER1_APPLIS="test/version.html test2.version.jsp"

# Liste des clusters à tester
CLUSTERS="CLUSTER 1"

# Liste des servers à tester
SERVERS="CLUSTER1_SERVERS"

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


for applis in $CLUSTER1_APPLIS
do
CONTENT=$(wget -q -O - "http://$SERVERS/$applis")
if [ "$CONTENT" != 1 ]
then
exit_code=2
else
exit_code=0
fi
done

case $exit_code in
"2")
echo "CRITICAL - App Version Mismatch"
exit 2
;;
"1")
echo "WARNING"
exit 1
;;
"0")
echo "OK - All apps have the save version"
exit 0
;;
*)
echo "CRITICAL - there's something wrong with this script ..."
exit 2
;;
esac



this script dosent seems to work, i think there is some pbr in the line (comparison)


if [ "$CONTENT" != 1 ]


any help or suggestions

thanks in advance

what is the outcome expected from :

Code:
wget -q -O - "http://$SERVERS/$applis"

?

hello panyam

wget prints the content of the web pages in standard output

I am more intereseted in the output of the below command:

Code:
wget -q -O - "http://$SERVERS/$applis"

Does it returns just "0" or "1", since you are comparing the outcome of the command against "1".

no the wget does not return 0 or 1

wget -q -O - "http://srv1/test/version.html
