Check if any argument matches using helper func

I have this:



ql_match_arg()
 declare -a my_array=$1
 for var in "$my_array[@]"; do
 if [[ "$var" == "$2" ]]; then
 return 0;
 fi
 done



ql_ls () 
 local my_array=( "$@" ); ql_json=$(ql_match_arg my_array[@] '--json' && echo "yes")
 ql_pid="$$" ql_json="$ql_json" ql_node_ls_all



what I am trying to do is create a helper function (ql_match_arg) which can be used by other functions to determine in any argument matches a given name. In this case, I want to find out if the --json flag is passed as any argument to ql_ls.



The problem I have is that it's not looping over my_array - something is wrong with my code - either I am not passing the array to ql_match_arg correctly, or something else is wrong.

The problem I have is that it's not looping over my_array




With this:



declare -a my_array=$1


You are creating an array with just one value: $1, the first argument passed to your script. So there is not much to loop over there.



If you want all arguments, try:



declare -a my_array=$@


Instead.

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...
