Put it in .bashrc and then call .bashrc from .profile (unless 
..bash_profile exists; only for bash.)

e.g.
# if running bash
if [ -n "$BASH_VERSION" ]; then
     # include .bashrc if it exists
     if [ -f "$HOME/.bashrc" ]; then
	. "$HOME/.bashrc"
     fi
fi

..profile is called by a login shell
..bashrc is called by interactive bash shell
