[ns] bash ns command not found

[Livian Zah]

Hi
I have installed Cygwin and configured network simulator2 in it but when ever I try to run it, it gives that bash ns command not found.
   
  I m using following .bashrc file :
   
  export PATH=$PATH:/home/Livian/ns-allinone-2.31/bin:/home/Livian/ns-allinone-2.31/tcl8.4.14/unix:/home/Livian/ns-allinone-2.31/tk8.4.14/unix
  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/Livian/ns-allinone-2.31/otcl-1.13:/home/Livian/ns-allinone-2.31/lib
  export TCL_LIBRARY=$TCL_LIBRARY:/home/Livian/ns-allinone-2.31/tcl8.4.14/library

  How can I locate binary files ?  Expecting kind reply.
Thanks
