I was debugging a service that was spitting out a particular log line. I gave Copilot an example line, told it to write a script that tails the log line and serves a UI via port 8080 with a table of those log lines parsed and printed nicely. Then I iterated by adding filter buttons, aggregation stats, simple things like that. I asked it to add a "clear" button to reset the UI. I probably would not even have done this without an AI because the CLI equivalent would be parsing out and aggregating via some form of uniq -c | sort -n with a bunch of other tuning and it would be too much trouble.

It can be anything. It depends on what you want to do with the output.

You can have a simple dashboard site which collects the data from our shell scripts and shows your a summary or red/green signals so that you can focus on things which are interested in.
