Bash to Deno examples

Bash has a number of peculiarities, particularly when it comes to error handling, and long Bash scripts can become complicated to maintain for teams with little experience of the language.

Deno seems a good alternative, with Typescript for typing and a modern API for accessing local resources (File System, I/O, Sub Process, ...).

This examples bash-to-deno.ts use Dax library :

Cross platform shell tools for Deno inspired by zx.

From https://github.com/google/zx :

Bash is great, but when it comes to writing more complex scripts, many people prefer a more convenient programming language. JavaScript is a perfect choice, but the Node.js standard library requires additional hassle before using. The zx package provides useful wrappers around child_process, escapes arguments and gives sensible defaults.
