Hi all

I need your help very urgently.

I am a newbie at Knoppix, I need your help. In my computer I have Windows XP installed, however, I want to use a software (OMNeT++) and make different simulations from console, for this reason, I need to run on Linux OS.
I have a Live-CD with knoppix. I boot my PC from CD and Knoppix is launched, in my directory I decompress OMNeT++ (in omnetpp sub-directory as it is mentioned after) software and these are the next instructions to be followed and I need some help:

##A sub-directory called omnetpp will be created which will contain the simulator
files. You should now add the following lines to your startup file (.bashrc
or .bash_profile if you're using bash; .profile if you're using some other
sh-like shell):

export PATH=$PATH:~/omnetpp/bin
export LD_LIBRARY_PATH=~/omnetpp/lib

For these variables to be included in the environment you will need to
restart the shell before proceeding (logout and login again).##


When is referring to the shell, is it simply the Console? I use Console to introduce the commands, where can I found the startup file to add these lines that are required to use OMNeT software?
Please could you let me know how to modify startup file?


Many thanks in advance.
