problem with envionment variables

[zhangli-pear]

My program work with envionment variables, but it's seems like it cann't find them when I run flamegraph.

so how can i pass all the envionment variables to my program? And I'm working with MacOS.

I'm experiencing the same issue.

This happens with --root only, since sudo doesn't pass through environment variables by default. I'm not sure if doing that by default is a good idea though (it's not the default for a reason).

root is required to run the command. Is that possible to add an option to allow passing envionment variables explicitly.

Are maintainers open to a PR?

Do people prefer:

• an extra flag to pass?
• always passing with --root?

Yes, I'm open to reviewing a PR. I think it should be explicit, would be nice if you can research what other existing tools use for the name of such an option. Looks like sudo calls it --preserve-env, so that might be a reasonable option?

The question I have is: how to pass through environment variables at all? I am using env-logger and cannot get my logs without hardcoding a logging level.

Okay. Running with sudo --preserve-env=… without --root works.
