How to pass environment variable to mongo script

Question

I want to pass the environment variable named file_path to js file.

I am using the following syntax:

mongo --eval \"var file_path=\'$fil         


        

Answer 1

Looks like Native Method shellGetEnv() has been added meanwhile, see MongoDB GitHub

So, would be simple

shellGetEnv("file_path")

However, the method is not documented and it looks it is not accessible from Mongo shell. Perhaps it becomes available in future releases.
