You need at least one Output:Variable object specified in your IDF file to generate an ESO file. You'll also need an Output:Meter object to generate an MTR file.

FYI: the shell script is no longer needed now that EnergyPlus has a real command line interface. You can run any file using energyplus -w weather_file idf_file. The -r flag will automatically run ReadVars after the simulation. You can type energyplus -h for more details on how to use the command line interface.
