Bash array using system positions limits? [closed]

Here is my array declaration 



arraySYSTEM=( "$@" )


It can have up to 10 "system position(?)" members.



I'm using it to build text parameters passed to whiptail function. Then I select the parameter using whiptail checklist (menu). In checklist I can have unlimited number of parameters using $number syntax - such as $16.



How do I modify my arraySYSTEM declaration to have more that 10 members in an array?






bash array

    Who says that array can have only up to 10 values?

  • If I code this way $10 it fails - highlights the "0" so $10 is OK. Perhaps using wrong syntax WAS my initial error.

You can have any number of entries in an array. For example:



$ set -- a..z
$ echo "$26"
z


(beware $26 is $26 in bash and most other Bourne-like shells)



Ditto for a named array:



$ foo=(a..z)
$ echo "$foo[25]"
z


(The indexing discrepancy is because $0 is special, usually containing the name of the current script.)

    Note that the $26 being $26 Bourne design flaw (in the Bourne shell not even $26 worked though "$@" still included all elements) is fixed in csh, tcsh, zsh, rc, es...

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
