ksh93 supports long options the same way as introduced by Sun Microsystems in Spring 2004 for getopt(3), Bourne Shell and ksh88.



You may e.g. use:



getopt(argc, argv, "V(version)");


to establish a long --version alias to the short option -V.



However ksh93 does not use the getopt(3) from Solaris libc but an own implementation that internally is used to support short options that start with a + sign.



Is there a way to use this feature with the ksh93 builtin getopts(1)implementation and iff, how does it work?

    Try getopts --man 2>&1 | more in ksh93 for details.

  • I discovered this some time ago already, I however have been unable to understand it since there are no examples and the ksh concept seems to complex as it includes support for --help IIRC. Do you know examples for this +o feature?

  • Yes, by brain is not tuned to parse that man page either. There are plenty of examples in the ast-open source code though.

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...
