Hi all,
I'm trying to use a bash script to know when a host needs updates. I executed it doing
./script_name
and the result is ok.
But when it is monitorized in zabbix, the returned values are wrong when looking at the item history. Something strange is happening, like it always evaluates the condition to false.
Here is the script
#!/bin/bash
apt-get update
if [ $(apt-get dist-upgrade -V -s | grep "0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded") ]
then
echo 9
else
echo 5
fi
For example, when I do ./script_name, the returned value is 9, but at the same time, in bash history the returned value is 5.
Somebody can help me please? I don't understand what's happening.
