Hi Bart,

I tried with dtruss; but it was giving error for built-ins

dtrace: failed to execute echo: (os/kern) failure

There might be other ways, but I am no expert in shell and dtruss.

Please let me know if I can do anything else.

Regarding the discussion in nvm github, can you please post your query over there?

Like I mentioned above, I am no expert and your inputs there will help the others in the discussion as well

Thanks,

Anand

Has anyone tried using "dtruss" on the process to see which system
calls may be blocking?
