In the man page for the eslogger tool, there is a reference to the jq tool.
Postprocess the output in a shell pipeline with jq:
% sudo eslogger exec | jq -r 'select(.process.executable.path == "/bin/zsh")|"(.process.audit_token.pid): (.process.executable.path) -(.event.exec.target.executable.path)"'
The problem is that the jq tool is not installed by default with macOS.
[Q] Isn't the idea that the man page should only reference tools that are part of the standard macOS distribution (or can be downloaded and installed by the OS when you try to run them, like with some developer tools)?
