paul,

to the best of my knowledge, the syntax in check_failure.sh is
correct and the problem is most likely a "feature" in ubuntu.

are you certain that /bin/sh is actually pointing to bash?

unfortunately, there is no good solution. you could make 
/bin/sh a symlink to /bin/bash, but that will probably break 
other scripts, e.g., those that control your startup.
that reminds be a lot of the situation way back when i 
had an IBM RS/6000 320h as desktop. the proper bourne shell
was in /bin/bsh, but if you put that in your shell scripts,
they become non-portable, and you couldn't change use /bin/bsh
as /bin/sh as it would break the many and elaborate shell
scripts that controlled the machine. <sigh>.

cheers,
    axel.
