Shankar,

The bash man page says

   An interactive shell is one started without  non-option  arguments  and
   without  the  -c  option  whose standard input and output are both con-
   nected to terminals (as determined by isatty(3)), or one  started  with
   the  -i  option.   PS1 is set and $- includes i if bash is interactive,
   allowing a shell script or a startup file to test this state.

I suspect that your bash may be getting confused about whether it's
running interactively.  Try printing $- from inside bash.  Also try giving
the '-i' option to bash and see if it helps.
	Igor
