`--env-var "foo=bar"`

you can goto the npm page to see all supported command line options , for passing a variable foo with value bar , you can use --env-var flag as shown

That’s not possible as of now , when ever you are accessing variables in script section use pm.variables.get() instead of specifying the scope so that the value will be resolved according to precedence

Eg if only collection variable is available then that is retrieved , if both collection and environment with same name exists then value will be from environment.

As lower scope has higher precedence
