Re: [ns] bash file for ns2

Hello

In order to pass your desired simulation values as function parameters from
a bash script, you should do it this way:

#!/bin/bash

#stuff....

#call the simulator

./ns Source.tcl argx0 argx1 argx2 etc

in the bash file
and in the tcl file

set var1 [lindex $argv 0]
set var2 [lindex $argv 1]
set var3 [lindex $argv 2]
set etc [lindex $argv 3]

and so on. var1 corresponds to argx0 by doing this. Now, to pass a bash
variable to the script I suggest that you search for a bash tutorial. It is
an easy thing to do, and very useful.

Israel Herrera.
