  We show that restricted shareability of multi-qubit entanglement can be fully
characterized by unified-$(q,s)$ entropy. We provide a two-parameter class of
bipartite entanglement measures, namely unified-$(q,s)$ entanglement with its
analytic formula in two-qubit systems for $q\geq 1$, $0\leq s \leq1$ and
$qs\leq3$. Using unified-$(q,s)$ entanglement, we establish a broad class of
the monogamy inequalities of multi-qubit entanglement for $q\geq2$, $0\leq s
\leq1$ and $qs\leq3$.
