I am not good at knowing Linux at all beyond some general concepts. If I did my brain would have no room left. However when dealing with it I always assume that it has everything and do google search. I do not remember a single case when I would want to write some utility. The ones available along with bash always cover all of my needs leaving me more time to design and implement the actual software I am being paid for. My whole CI/CD or whatever complete management is called is few bash scripts.
