I am trying to use ls and grep. However, I cannot figure out a way to count how many files in the current directory have a name long at least 5 characters.



How can I achieve this?




files grep ls

Simple find + wc commands solution:



find . -maxdepth 1 -type f -name "?????*" | wc -l

    If this is homework, the assignment may be looking for something like:



    ls | grep ..... | wc -l


    Though I would do:



    set -- ?????*
    echo $#


    or



    files=(?????*)
    echo $#files[@]


    Here the important work is done by the shell glob . which says to match one character of a filename; by including 5 of them followed by a * (any number of characters), we generate the list of files with at least 5 characters in them.



    The counting is then done by the $# shell parameter in the set solution, or by counting the elements in the array.

                      How many registers does an x86_64 CPU actually have?

                      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.
