Looking for any discussions where you have strong opinions,because I probably do.
Mostly work in Golang nowadays, although have worked with Python and Javascript in the past.
Thanks for the tip Thomas. I usually do use $() but didn't know that you don't need to escape nested command execution with it. Initially I used $() along with {} and it lead to errors on Mac (but not on Linux), so I switched to back-ticks which worked on both.
I'll update the article once I get near my computer and can test this out on both Mac and Linux, thanks again.

Yeah... Being a long-time abuser of nested subshells, used to frustrate the hell out of me once I had to go more than about two subshells deep ...Sooner if one or more of those subshells required single- and/or double-quotes for some of their functionality.
Wasn't really until I started adding shellcheck to my TravisCi recipes that I habituated to the $() method. That tool also caused me to start moving off a few other habitual things that had been placed on the deprecation (but had worked for decades so were just "finger memory").
For further actions, you may consider blocking this person and/or reporting abuse
