Sorry I wasn't clear enough. Although ROOT does not allow you to define functions within rootcint, you can always define such functions in a root macro.

To retain your workflow all you need is to change the shebang line from root to bash/<whatever shell you use>.

An example:

#!/bin/bash

root -l -b <<EOF
.L someROOTmacro.C+
someROOTmacro(..)
.q
EOF The added advantage of this method is you can do all kinds of string manipulation with the arguments you pass to the script with usual shell scripting tricks. For the lack of a better name, your script becomes a "bi-lingual" script (bash and ROOT).
