Recently I’ve really been trying to get into [Genie](https://github.com/GenieFramework/Genie.jl). To launch a Genie app, you either have to memorize a long command or just run one of 4 executables located in [the bin directory](https://genieframework.github.io/Genie.jl/documentation/4--Developing_Web_Services.html).

I noticed I was getting an error

> “command not found: julia”

I won’t pretend to be a shell expert so I’m here to ask for help. It was set to run in _sh_ and I’m on a MacOS Catalina which seems to have switched to _zsh_. I’ve tried changing the shebang to:

```bash
#!/bin/zsh

```

and am still getting “command not found: julia”. I can run the command if I copy paste it into my terminal so what gives?

You have to make sure `julia` is in your `PATH` if you want to run it from the command line. On MacOS, I usually create a link:

```nohighlight
sudo ln -s /Applications/Julia-1.4.app/Contents/Resources/julia/bin/julia /usr/local/bin/julia

```

to create a symbolic link `/usr/local/bin/julia` to the Julia “app” installed in your `Applications` folder.

Oh sorry, I forgot to explicitly mention julia was already is in my PATH. Like I said, copying the full command into the terminal works just fine, but it’s somehow missing from the _PATH_ for _bin/sh_, if that makes any sense. It shouldn’t be any different? Is it?

Depends on how you set your `PATH`. If you set it in `~/.bash_profile`, that won’t do it for `/bin/sh`, for example. (I think `/bin/sh` uses `~/.profile`.)
