How to remove trailing line in Shell

[jaigs_27]

am getting trailing line, how can I remove that, see below
$test = ssh hostname cat /proc/cpuinfo |grep -i 'model name'
echo "$test"

(standard input):model name : Intel(R) XEON(TM) CPU 2.40GHz
<trailing line>

And when I am checking value in variable, nothing is there

if [ -n $test ]; then
echo "$test"
else
echo "Error"
fi

but nothing is happening, even else is also not executing

Try:

test=ssh hostname cat /proc/cpuinfo |grep -i 'model name'
