What problem are you trying to solve? If you tell us that, we can guide you
to some better solutions.

There are numerous issues here, but the most important are:

1) Calling a shell via \! invokes an entirely new process: there is no link
to the parent or grandparent process

2) The run-bash-function must be declared before being called, so that bash
code was never going to work anyway. In other words, this is valid:

run-bash-function() { echo "Here we are"; }

run-bash-function

This version is not:

run-bash-function

run-bash-function() { echo "Here we are"; }


Cheers,
Greg
