Dewey shared with me a script to launch a RIP configuration instead of typing a bunch of stuff in a terminal. Sure makes it easier to work with a RIP configuration.
rip.sh
#!/bin/bash
# put this file in your path (example ~/bin)
# make it executable too (chmod 755 this)
RIPHOME=/home/git/emc
INIFILE=$RIPHOME/configs/sim/ngcgui/ngcgui.ini
source $RIPHOME/scripts/rip-environment
