How can we tweak the below script to get the preferred result?
If the entry "KEYBOARD_ALTERNATE=alternate" is not uncommented, then I should get a failure.
======================================================
# Verify alternate break signal is enabled on SUN systems.
#
if [[ `uname -s` != 'SunOS' ]] ; then
addskip "This is not SunOS so skip to check"
exit
fi
if [[ `grep "^KEYBOARD_ABORT\=alternate" /etc/default/kbd` != '' ]] ; then
addfailure "break signal not enabled"
else
addsuccess "break signal enabled"
fi
==========================================================
Thanks..

sigaltstack
sigaltstack(2) System Calls sigaltstack(2)
NAME
sigaltstack - set or get signal alternate stack context
SYNOPSIS
#include <signal.h>
int sigaltstack(const stack_t *restrict ss, stack_t *restrict oss);
DESCRIPTION
The sigaltstack() function allows a thread to define and examine the state of an alternate stack area on which signals are processed. If ss
is non-zero, it specifies a pointer to and the size of a stack area on which to deliver signals, and informs the system whether the thread
is currently executing on that stack. When a signal's action indicates its handler should execute on the alternate signal stack (speci-
fied with a sigaction(2) call), the system checks whether the thread chosen to execute the signal handler is currently executing on that
stack. If the thread is not currently executing on the signal stack, the system arranges a switch to the alternate signal stack for the
duration of the signal handler's execution.
The stack_t structure includes the following members:
int *ss_sp
long ss_size
int ss_flags
If ss is not NULL, it points to a structure specifying the alternate signal stack that will take effect upon successful return from sigalt-
stack(). The ss_sp and ss_size members specify the new base and size of the stack, which is automatically adjusted for direction of growth
and alignment. The ss_flags member specifies the new stack state and may be set to the following:
SS_DISABLE The stack is to be disabled and ss_sp and ss_size are ignored. If SS_DISABLE is not set, the stack will be enabled.
If oss is not NULL, it points to a structure specifying the alternate signal stack that was in effect prior to the call to sigaltstack().
The ss_sp and ss_size members specify the base and size of that stack. The ss_flags member specifies the stack's state, and may contain
the following values:
SS_ONSTACK The thread is currently executing on the alternate signal stack. Attempts to modify the alternate signal stack while the
thread is executing on it will fail.
SS_DISABLE The alternate signal stack is currently disabled.
RETURN VALUES
Upon successful completion, 0 is return. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The sigaltstack() function will fail if:
EFAULT The ss or oss argument points to an illegal address.
EINVAL The ss argument is not a null pointer, and the ss_flags member pointed to by ss contains flags other than SS_DISABLE.
ENOMEM The size of the alternate stack area is less than MINSIGSTKSZ.
EPERM An attempt was made to modify an active stack.

NOTES
The value SIGSTKSZ is defined to be the number of bytes that would be used to cover the usual case when allocating an alternate stack
area. The value MINSIGSTKSZ is defined to be the minimum stack size for a signal handler. In computing an alternate stack size, a program
should add that amount to its stack requirements to allow for the operating system overhead.
The following code fragment is typically used to allocate an alternate stack with an adjacent red zone (an unmapped page) to guard against
stack overflow, as with default stacks:
#include <signal.h>
#include <sys/mman.h>
stack_t sigstk;
sigstk.ss_sp = mmap(NULL, SIGSTKSZ, PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANON, -1, 0);
if (sigstk.ss_sp == MAP_FAILED)
/* error return */;
sigstk.ss_size = SIGSTKSZ;
sigstk.ss_flags = 0;
if (sigaltstack(&sigstk, NULL) < 0)
perror("sigaltstack");
