In cases, where $G_I$ is a cycle or a tree, we show the following are equivalent:\n  (a) $ I $ has a linear resolution\n  (b) $ I $ has linear quotients\n  (c) $ I $ is a variable-decomposable ideal\n  In addition, with the same assumption on $G_I$, we characterize all monomial ideals with a linear resolution. Using our results, we characterize all Cohen-Macaulay codimension $2$ monomial ideals with a linear resolution.
