Cannot disable warnings when node is launched via a shell script.

[dzrw]

As an end-user, I don't want to ever see warnings or deprecations. However, when node is invoked from a shell script via a shebang, there is no opportunity to pass the --no-warnings option to the process.

#!/usr/bin/env node --no-warnings
console.log("you will never get this far, so it doesn't matter if this compiles");

Is there an environment variable that can be set to toggle this option? If not, please add support for something like NODE_NO_WARNINGS=1.

What's the solution?

When I try putting this at the top of my file:

#!/usr/bin/env NODE_NO_WARNINGS=1 node

I just get:

/usr/bin/env: ‘/path/to/my/script’: Text file busy

@mnpenner
like this:

#!/usr/bin/env
export NODE_NO_WARNINGS=1

it works. :)
