FreeLists / oracle-l / RE: PART II: - Beyond a basic Oracle EXP/IMP shell script: Error Handling & Exit Status?

["Marquez, Chris" <cmarquez@xxxxxxxxxxxxxxxx>]

Guys, I'm stuck?

I have two scripts;
 - export_simple_script_wrapper.sh
 - export_simple_script.sh


export_simple_script.sh seems to work every time and in the logs shows the 
correct "$RC" (=$?) every time for the right failure (or success).

export_simple_script_wrapper.sh works, by calling export_simple_script.sh but 
the log output and "if" logic proves that it is always getting success "0" when 
export_simple_script.sh tells other wise.

I have provided (I hope) enough log and script info below for your help in 
finding my problem.

Thanks in advance,
