The Template#

Since I can never truly remember all there is to bash, i've made a template I re-use for a lot of my bash scripts, to remind myself of useful starting points. I'll post the whole template first, and then I'll explain it in smaller sections below.

GIT Co-Authors#

GitHub and GitLab both support the idea of co-authors which allow a user to attribute a commit to more than one author by adding one or more Co-authored-by trailers to the commit's message.

Co-author attibuting looks somethink like the following in the commit message.

Infrastructure Breakdown#

I prefer using a monorepo approach for my Terraform configuration, based on a primary provider. So take this example folder structure, where I work with Sumo Logic and AWS and then read more below on how all this works out in practice.

I need these key/value pairs from JSON exported to the environment

There have been a few times where I've needed to take the contents of a JSON object and export them to the environment. While there are surely lots of way to do this with awk, sed and/or jq in combination, I've opted to just create a bash function for it.

Regular Expressions are great, but not easy to look at!

Let's take for example a regular expression in Javascript for parsing an email adddress.

To a trained eye this is likely as least readable enough, that they can guess that this parses an email address. But most people I work with, and myself included aren't going to be able to tell if there are any obvious bugs in this.

Sumo Logic's parseDate(strDate>, <dateFormat>, <timeZone>) operator allows queries to extract a timestamp in milliseconds from a string. The operator functions in a fairly straight forward way, by using a dateFormat parameter (based on Java's SimpleDateFormat)
