just trying to get a good mental model of when it’s reasonable to use tools like awk instead of simpler unix tools. also further confirming that sed is almost never the best tool except for substitutions.
Sed and awk have a lot of overlap. Another thing to consider is that neither might be the right choice if you are inside a bash script since spawning a new process in a tight loop can be very expensive and bash’s built-in regex operations can have much better performance in those situations.

That’s a good point. If I need something like a bash script I tend to stick to bash features as much as possible.
