First what I’m trying to do:

```julia
using Distributed
addprocs(1)

target = string(@ __DIR__ , "/dir2/d2.jl")
@everywhere include(target)

```

With a directory structure like:

- /dir1
  - m1.jl
  - /dir 2
    - d2.jl

The above code is in m1.jl. This is giving me an error `UndefVarError: target not defined` on worker 2. For development I’m running this under Atom, which means the root directory from which julia is started is the root of the project. However when running “normally” I would expect my current directory to be “dir1”…probably.

The above could (if it worked) also handle the situation if the current directory is NOT dir1, like if I executed: `julia ~/project/dir1/m1.jl` from the console. If I just did `@everywhere include("dir2/d2.jl")` I’m restricted to only being able to run if my current directory is `dir1`.

Try:

```julia
@everywhere target = string(@ __DIR__ , "/dir2/d2.jl")
@everywhere include(target)

```

Well that’s embarrassing, that worked. I didn’t try it because I just assumed `@ __DIR__ ` would expand on the distributed process…

Thanks for the help.

I think `@ __DIR__ ` is not the issue in your code.  
The problem is that target is only defined in the main process.

Or interpolate the value of `target`:

```julia
target = string(@ __DIR__ , "/dir2/d2.jl")
@everywhere include($target)

```
