Working command line arguments fail in shell script

[TimorousMe]

After some great help from this forum I've nailed down my Gimp plugins and bash shell commands. However I want to launch them from a shell script and they're failing from there. 

I'm on OS X Mojave. 

Here's my bash shell command:

Code:

gimp -idf --batch-interpreter python-fu-eval -b "import sys;sys.path=['.']+sys.path;import OAFE_PARAM;OAFE_PARAM.open_add_flatten_export('/Users/TimB/Desktop/xcftemplate.xcf', '/Users/TimB/Desktop/jpg_to_add.jpg', 2060, 410, '/Users/TimB/Desktop/')" -b "pdb.gimp_quit(1)"

OS X shell scripts don't recognize my Gimp alias, so I try to launch this and it fails. 

Code:

/applications/GIMP-2.10.app/contents//macos/gimp -idf --batch-interpreter python-fu-eval -b "import sys;sys.path=['.']+sys.path;import OAFE_PARAM;OAFE_PARAM.open_add_flatten_export('/Users/TimB/Desktop/xcftemplate.xcf', '/Users/TimB/Desktop/jpg_to_add.jpg', 2060, 410, '/Users/TimB/Desktop/')" -b "pdb.gimp_quit(1)"

Here's the error I see:

Code:

GIMP is started as MacOS application

gimp_check_updates_callback: loading of https://www.gimp.org/gimp_versions.json failed: Operation not supported

Any thoughts on what I could do differently?

Starting with "open" at the beginning doesn't work because then it treats my command line parameters as parameters for "open" and not for Gimp.
