Read / Write and display environmental variable

[jimoo]

Looking for a script that can read an environmental variable and then display it. Also, looking for a script to write to one.

Would like to be able to test interactively.

Javascript is not allowed to access or modify environment variables

Hi

Unless the question is not about client-side JavaScript. Jim, please clarify abit on your goals.

For example in node.js you can access them with [tt]process.env[/tt], so displaying is just [tt]for [teal]([/teal]var key in process[teal].[/teal]env[teal])[/teal] console[teal].[/teal]log[teal]([/teal]key[teal],[/teal] [green]'='[/green][teal],[/teal] process[teal].[/teal]env[teal][[/teal]key[teal]])[/teal][/tt].

Regarding the "write" part, there is a limitation node.js warns about ( but equally valid for other languages/environments too ) :

You can write to this object, but changes won't be reflected outside of your process.
