I am trying to pass an argument from the terminal to a program that uses multiple cores. But ARGS appear to be visible only on the first worker. How can I push ARGS to all workers?  
For example, suppose test.jl contains

using Distributed  
addprocs(1)  
@everywhere model=ARGS[1]  
println(model)

When I run in the terminal  
julia test.jl Hello

worker 2 does not see ARGS variable and Julia throws an error.

As described in the [manual](https://docs.julialang.org/en/v1/stdlib/Distributed/#Distributed.@everywhere), `@everywhere` does not capture variables, so you need to interpolate them:

```julia
@everywhere model=$(ARGS[1])

```
