As a bit of a digression it is also true in both bash and ksh that the index for arrays (between [ and ]) can be an arithmetic expression.
So in the above posts ${arr2[(($names - 1))]} can be replaced with ${arr2[names-1]} and ${arr[$i]} can be replaced with ${arr[i]}
Yes. But, ksh and bash don't handle everything used as a subscript the same way. With the following code: ksh version 93u+ gives me:
while bash version 3.2.57(1) gives me:
and the diagnostic:
To make that work correctly in both bash and ksh, I have to use:
I believe there are other differences as well, so I tend to use more code than needed when writing array element references that I want to be portable across various shells that support arrays.
The standards don't yet specify shell array variables, so each shell decides what shortcuts, if any, can be taken when referencing arrays if that shell supports arrays at all.
Hello -

So, I'm fooling around with multi demtional arrays, and I made this in a short amount of time:

};

while (i < 2) {
if (argv == blah)
printf("%c\n", blah);
i++;
}
}
