Refactor your terrible and hard to maintain script into a well looking and maintainable script. It's not a bash fault. My bash-modules[0] project[1] may help you with that. Typically, I perform script refactoring in these steps: 1. Split code into few subroutines with clear boundaries between them, or split a large script into multiple simpler scripts. 2. Add an error handler with transparent message to every line of code. 3. Add command line options to override hard-coded things, to be able to test things in isolation. 4. Write documentation (man-page) for script, for future self. 5. Write test cases. 6. Refactor code, following best practices.
