How to provide custom NS functions to all users

[Mitchell Carroll]

I'm trying to provide a program to run on nodes at startup that is opted into through the experiment ns file.  The program will load from a git repo available through the user's directory on ops, since this is our only option with nodes not having direct internet access.  Can I add a command to the interpreter the way you can with a normal TCL interpreter?

Hi: In your NS file you can do this:

set n1 [$ns node]

# Create a program object and attach it to the node
set prog1 [new Program $ns]
$prog1 set node $n1
$prog1 set command "/bin/ls -lt >& /tmp/foo”
