ERROR-> test: argument expected , what does it mean?
I am trying to compare two integer variables in the if statement, but i am getting this "test:argument expected".
What am i missing?
Why is the if loop not executing correctly?
trunkPCM="100000";
more $FILE |while read line
do
PCM=`echo $line | awk '{ print $2 }'`
if [ -n "$PCM" ]
then
echo "$PCM, $trunkPCM";
if [ $PMC -eq $trunkPCM ]
then
trunkPCM=$PCM;
fi
fi
done
Thanks for your help!
