Defensive BASH Programming

If you write any Bash code that lasts more than a day, you should definitely read “Defensive BASH Programming” and follow the advice, if you haven’t already.  It covers the following:

  • Immutable global variables
  • Everything is local
  • main()
  • Everything is a function
  • Debugging functions
  • Code clarity
  • Each line does just one thing
  • Printing usage
  • Command line arguments
  • Unit Testing

All that with code examples and explanation of importance.
