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
run-bash-function
This version is not:
run-bash-function
run-bash-function() { echo "Here we are"; }
Cheers,
Greg
