Question string to number
In the following script when I get SIZE1 and SIZE2, they are of type string. I can not do any mathematical operations on them. I wanted to find out if I can convert string in to Number. Thanks in Advance.

FILE1='/export/registry/incoming/reg.dmp'
FILE2='/export/registry/reg.dmp'

SIZE1=`ls -l $FILE1 | awk '{print $5}'`
SIZE2=`ls -l $FILE2 | awk '{print $5}'`

if [ $SIZE1 > $SIZE2 ]
then
echo $SIZE1 - $SIZE2
else
echo "The 1st file is smaller."
fi
