That’s true, and it’s the reason the tools I mentioned were written in Bash in the first place. Python 2/3 was a pain, Ruby had very disparate versions available. But now, a few years later, you can assume at least Ruby 1.9 nearly everywhere, and OTOH still can’t use any of the Bash 4 features. There also quite decent cross-platform packaging solutions for python, ruby, node, go, crystal, mruby that make it really hard to choose bash for any serious project.
