Dependency on awk
The shell implementation requires the ability to do floating point calculations for calculating exponential backoff. Out of the workable options, I found only awk available in the minified system images I was working with. I suppose this dependency could cause problems for some. Should implementations for others be included? Others that could work: python, ruby, bc, dc
Please check https://github.com/kadwanev/retry/pull/12 I've added built-in bash, bc and perl to the mix of calculators.
LOVE IT! Let me just test it in the next couple days and merge. Thank you for your contribution!
