This is arguably slightly tidier and perhaps safer, since the command isn't run through a shell.

Nifty, I never knew of that method.

In your PR there is an incorrect space prefix of the version arg string, which would cause a failure.

I'll be tearing apart safeps in the coming months, into multiple promise and purpose based packages.

Are you actively using safeps?

[max-schaefer]

I am not currently using safeps, so feel free to close this.

Thanks for the PR update. I'll merge when I get to the pr queue on my current roadmap, such that I can validate the changes in @docpad: https://github.com/orgs/bevry/discussions/1
