Strictly speaking, == is used to compare strings. You'd like to use -eq to compare integer values. In the following example string comparison will fail even if integer value is the same:

    a=010
    b=10
    if [ $a == $b ] ; then
            echo "A == B"
    else
            echo "A <> B"
    fi

But if we change test operate to -eq

    a=010
    b=10
    if [ $a -eq $b ] ; then
            echo "A == B"
    else
            echo "A &lt;&gt; B"
    fi

Result will be A == B

You have to rewrite [ $a == $b] to [ $a == $b ].
