No, it shows that you are already running ns. You do not run a tcl script from inside ns. You run it from a command line.

1. Open a new Terminal window. For "standard" Linux installations, you will see a prompt ending with a '$' and the current directory will be in your home directory. Depending on your setup, the prompt may or may not have other stuff, but for normal users (not root), the default prompt will end in a '$'

2. You can cd to wherever you want to be when running ns. You will still see a prompt ending with a '$'

3. From that command prompt, you do not (that's not) enter


4. If you have cd'ed into the directory where simple.tcl resides, you enter

5. If your current directory is not the place where simple.tcl resides, you can enter

Halo Dave!

hehe.I like your footnote very much..Good reminder for everyone..

bytheway..

1)
I learn something here as before this i have been using the "%" sign to start executing the ns2. The "$" sign is always there when i open up a new terminal window.

2)
For your info., my simple.tcl resides in my Desktop directory. So I opened up a new terminal window and i changed my directory to my Desktop. I run this command :


However i got error message saying " simple.tcl doesn't exist, try again "

No changes were made to the tcl script before and i am very sure i downloaded it correctly into my Desktop. I have also tried with other tcl scripts but i still got the same error message..

You show that the prompt is

The '~' indicates to me that you may be in your home directory, not your Desktop directory. I could be wrong, since my prompt is not set up as yours apparently is.

Why not move (or copy) the tcl file to your home directory and try again with a new terminal window? Or, you could change to your Desktop directory. Make sure the tcl file is in the directory where you are:


If it shows simple.tcl is in that directory, then

Or, if the file is in the Desktop directory, then, from anywhere you can do something like

But I never operate on stuff in the Desktop directory, since it tends to clutter up the Desktop with extra stuff that I really don't want to see. I'm funny that way.
