Maybe it’s becuase i grew up on python and bash still seems somewhat alien to me, but any time I’m crafting something with more than three or so nested functions, I use python as a wrapper for bash. Python initiates a bash script, parses the retval, inititates the next bash script from that data, etc.
It works for now, but the reason most wires have a rubber-like insulator around them is that it takes very little to Crack or abrade a thin coating such as this and turn it into a fire hazard.
I’m surprised a product with such a small safety margin is allowed for sale.
