  From an analysis of the spectrum (4000\AA to 8800\AA) of HD~101584 it is
found that most of the neutral and single ionized metallic lines are in
emission. The forbidden emission lines of [OI] 6300\AA and 6363\AA and [CI]
8727\AA are detected, which indicate the presence of a very low excitation
nebula. The H$\alpha$, FeII 6383\AA, NaI D$_{1}$, D$_{2}$ lines and the CaII IR
triplet lines show P-Cygni profiles indicating a mass outflow. The H$\alpha$
line shows many velocity components in the profile. The FeII 6383\AA also has
almost the same line profile as the H$\alpha$ line indicating that they are
formed in the same region. From the spectrum synthesis analysis we find the
atmospheric parameters to be T$_{eff}$=8500K, log g=1.5,
V$_{turb}$=13km~s$^{-1}$ and [Fe/H]=0.0. From an analysis of the absorption
lines the photospheric abundances of some of the elements are derived. Carbon
and nitrogen are found to be overabundant. From the analysis of Fe emission
lines we derived T$_{exi}$=6100K$\pm$200 for the emission line region.
