Read / Write and display environmental variable

Read / Write and display environmental variable

(OP)
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.

RE: Read / Write and display environmental variable

Javascript is not allowed to access or modify environment variables

RE: Read / Write and display environmental variable

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 process.env, so displaying is just for (var key in process.env) console.log(key, '=', process.env[key]).

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

Quote (Node.js Documentation | process | process.env)

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