Bash Version: 4.1
Patch Level: 0
Release Status: release

Description:
        Prohibited restricted shell command doesn't always return
non-zero exit
        status.

        Executing "/bin/ls" under a restricted shell returns a non-zero
exit
        status, as expected.

        However executing "/bin/ls && /bin/ls" under a restricted shell
returns a zero exit
        status. This is not expected (at least not by me!). Zero exit
status is returned with
        any list of commands, e.g. "/bin/ls && :".
         
        I need to know whether a command list executed under a
restricted shell
        succeeded or failed.


Repeat-By:
        $ bash --restricted -c "/bin/ls"; echo $?
        bash: /bin/ls: restricted: cannot specify `/' in command names
        1
        $ bash --restricted -c "/bin/ls && /bin/ls"; echo $?
        bash: /bin/ls: restricted: cannot specify `/' in command names
        bash: /bin/ls: restricted: cannot specify `/' in command names
        0
