From what you say there are two parts to the variable? Is it not possible to have 2 variables and just test the seconf one?

Actually, don't htink that helps because if the seond part is blank then no $2 will get set.

Sorry

seond_var=$(awk -F " " '{print $2}' ${var})

[[ ${second_var} = "" ]]
then
echo "no second_var"
fi

This should do it:

if [ "$(echo ${var1} | awk '{print $2}')" = "" ]
then
echo "anything"
fi

Hi Kamal,

Try this I could work.

if (test $var1 = `awk '{print $2}'`=" ")
than echo "anything"
exit
fi
