Thanks for trying out the patches.
I've gone back and forth on whether to make this function interactive.
On the one hand, it could be convenient, but on the other hand, calling
'eshell-command' interactively should also work: if you type "source
my-file.esh arg1 arg2..." at the 'eshell-command' prompt, that would do
more-or-less the same thing as calling 'eshell-execute-file'. You could
even add "> destination" to the end to redirect the output somewhere,
e.g. to a buffer.

My understanding was that --batch is supposed to prevent local init files from being loaded.

You'll probably need to use "env -S" in the shebang to split the args.
Shebangs treat everything after the first word as a single argument, so
Emacs sees "--batch -f eshell-batch-file" all together.
Something like this should work (I hope):
#!/usr/bin/env -S /home/christopher/local/bin/emacs --batch -f
eshell-batch-file
