Try setting the environment variable HISTFILE, before starting M-x shell, 
because otherwise history won't be saved for bash (at least that's the
case in Emacs 23 which I use).

Then you can try calling (comint-write-input-ring) from M-: after typing
some commands to see if it saves the inputs to the file you set in HISTFILE.

If it does then you can add an after advise to comint-send-input to call 
comint-write-input-ring after each command.
