How to see (and/or hear) the names of every process in macOS that starts or stops

@Airy

if you can "get the diff command to work with KM Variables," instead of files, I'm eager to see your solution.

See @Nr.5-need_input's reference above to process substitution, which though not the problem I was having, is discussed in that same thread by @drdrang:

By the way, you can avoid temporary files by using process substitution which is available in zsh and later versions of bash (e.g., the bash you can get from Homebrew). A shell script like

#!/bin/zsh
diff <(echo "$KMVAR_InstanceVar1") <(echo "$KMVAR_InstanceVar2")

will diff the contents of the two KM variables with no need to create and clean up temp files.
