[ns] problem with setting environment variables

[Onyekachi]

Hello ns-users,
Please I am a new user of the ns2 simulator. I just installed it 
(ns-2.29) without setting the environment variables properly. Anytime I 
try to run a *.tcl file i get the following message: 'bash: ns: command 
not found.
Please I would appreciate a step by step approach to resolving this problem.

N/B: My ns directory is *c:/home/ns-allinone-2.29/ns-2.29*

Thanks.
Onyekachi.

There is no shortage of web resources for answering unix questions
like how to set environment variables. You will need to add ns to your
PATH to get rid of the command not found error.

Hi Onyekachi,

You could run the following command to set your environment variable everytime 
you start your Cygwin.

export 
PATH=$PATH:/ns-allinone-2.29/bin:/ns-allinone-2.29/tcl8.4.11/unix:/ns-allinone-2.29/tk8.4.11/unix:/ns-allinone-
export 
LD_LIBRARY_PATH=/ns-allinone-2.29/tcl8.4.11/unix:/ns-allinone-2.29/tk8.4.11/unix/:/ns-allinone-2.29/tk8.4.11/
export TCL_LIBRARY=/ns-allinone-2.29/tcl8.4.11/library


Or you could add in the above into your .bashrc file and this will advoid you 
from setting environment variable everytime you run your Cygwin.

regards
-kc
