{{{/bin/sh}}} is a borne shell, but it is '''not''' POSIX compatible,
since to make it POSIX compatible would break backwards compatibility in
Solaris.
There are however other shells, such as {{{/usr/xpg4/bin/sh}}} which are
POSIX compatible. Hence there is a need to work around the Solaris shell
{{{/bin/sh}}}, and do not assume that it is POSIX compatible, since it is
not.
