In bash, i don't think it is possible. Well, you could do it like autoconf
does it. In configure, it checks for sys/param.h if it defines the byte
order, if not, it uses a little c-program:
main () {
/* Are we little or big endian? From Harbison&Steele. */
union
{
long l;
char c[sizeof (long)];
} u;
u.l = 1;
exit (u.c[sizeof (long) - 1] == 1);
}
But why do you need it? A program probably already uses this in
configure if it matters?
