Summary: The oscillation behavior of solutions of first order differential equations with forcing term and deviating arguments of the type \(y'(t)+\sum^ n_{i=1}p_ i(t)y(t-\tau_ i(t))=q(t)\) is considered. Some new oscillation criteria are established. The asymptotic behavior of solutions of a class of first order nonlinear delay differential equations is investigated. Some sufficient conditions for global attractivity are obtained.
