I’m hoping to run some simulations from a shell script. The structure is something like:

```julia
parent
  \__ Manifest.toml
  \__ Project.toml
  \__dir
    \__ sim.sh
    \__ env.jl
    \__ simulate.jl

```

where `sim.sh` contains

```julia
#!/bin/sh
julia simulate.jl

```

`simulate.jl` contains

```julia
include("env.jl")
println("...now running simulations...")

```

and `env.jl` contains

```julia
using Pkg
Pkg.activate("../.")
Pkg.instantiate()

```

to pull from Manifest/Project files I have in `parent/`. However, when I run `$ ./sim.sh`, I get the following error:

```julia
ERROR: LoadError: ArgumentError: Module Pkg not found in current path.
Run `Pkg.add("Pkg")` to install the Pkg package.
Stacktrace:
 [1] _require(::Symbol) at ./loading.jl:428
 [2] require(::Symbol) at ./loading.jl:398
 [3] include_from_node1(::String) at ./loading.jl:569
 [4] include(::String) at ./sysimg.jl:14
 [5] process_options(::Base.JLOptions) at ./client.jl:305
 [6] _start() at ./client.jl:371

```

Am I doing something wrong??

Ah, I just need to call julia from `$JULIA_BINDIR/julia` in the shell script and make sure the shebang references the current environment `#!/usr/bin/env sh`

@jacob\_roth It is very worthwhile documenting this. You are running the simulation in a batch system such as Slurm or PBS? There are differences between interactive and non-interactive login shells.  
I think you have come across a situation where the non-interactive shell is different.

I don’t need to see the output, which might contain proprietary information. Howwer could you submit a script which simply runs the env command and similary run env at the terminal, then do a diff of the results?

Of course, I may be wrong here.

@johnh: I think I was just using the “wrong” version of Julia. My default path wasn’t properly set up 🙂
