Ooh nice thought. I’m not certain, but I kinda doubt it’s possible, because those startup scripts need to modify the current shell environment. I believe GNU parallel runs in a subshell and launching new tasks in separate processes, so fundamentally doesn’t operate the same way that e.g. sourcing the nvm script does, unfortunately. Even if there was some way to hack it, I’d be nervous about changing environment variables in parallel, to me that sounds like asking for really nasty race condition bugs.
