Yes. String-parse the output of a command... hope it's not different on MacOS, or add special conditions to it... it's all very tedious. AI seems to do this stuff well due to the sheer number of examples people have produced, thank god, but I put in my decades of writing it by hand. The pipe is great, but Bash sucks as a language for many reasons, lack of types pretty low on the list but still on there somewhere.

Powershell seems to have fixed that a bit by passing objects around in the shell. On the unix side more and more utilities just serialize to JSON and we all expect `jq` - somehow not always installed, but still Perl always is...
