I am new to ksh scripts (still reading manuals). I need to write an application that reads a multi-line parameter file, builds sql on-the-fly, runs plsql and saves the output in a specific format for further processing. I am looking for anything on Best Practices for building such an application. How best to organize it, sub-divide it, test it, down to how best to format the code for clarity. Any book or white paper suggestions would be appreciated.
