Bash Version: 1.14
Patch Level: 7

Description:

        When a user's login shell is /bin/bash, output from the command

                bash -c pwd

        is prefixed with the [prompt?] string  "^[]2;\h^G", for example:

                [jjs@rh62 jjs]$ bash -c pwd
                ^[]2;rh62^G/home/jjs

        FYI:  uname -a

Repeat-By:

        Use chsh to set or change the user's login shell to /bin/bash;
        Login as that user;
        At the prompt, type in the any of the following commands:

                bash -c pwd          or  $SHELL -c pwd
                bash -c date         or  $SHELL -c date
                bash -c 'echo hi'    or  $SHELL -c 'echo hi'
                bash -c echo         or  $SHELL -c echo

        and observe the output.

        Some Workarounds:
                
                If /bin/sh is linked to /bin/bash,
                use  sh  or  /bin/sh  in place of  bash.
                
                If /bin/sh is linked to /bin/bash,
                use  chsh  to change the users' login shell to  /bin/sh
                (or  /bin/ksh  ... ).

        If there is code that uses  "$SHELL -c cdm_string" and
        one cannot guarantee that the user's login shell will
        not be  /bin/bash ,  it may not be so easy.
