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

There's a suggestion from the mongo change request:

alias mongo="export | sed 's/declare -x /env./' > shell.js; mongo $@; rm shell.js;"

Then in ~/mongorc.js:

var env = {};
load('shell.js');
