I would like to create mechanism to delete parentheses, or parentheses and the text between them. For example:



before:



text0 text1 text2 (text3 text4)


after: 



text0 text1 text2 text3 text4


or:



text0 text1 text2


I would like to test both options and other type of brackets but I'm not sure what tool should I use, Awk or Sed or maybe something else? I would be grateful for any advice.




shell-script text-processing awk sed

  • Can brackets be nested?

  • Good question. Let's say yes but only brackets that are deeply nested - file may be json and curly braces will be preseted in every case.

The other half of your question,
deleting just the parentheses (but not the text between them):



echo 'text0 text1 text2 (text3 text4)' |
 sed 's/[()]//g'




Output:



text0 text1 text2 text3 text4

    To keep the text, this is enough:



    tr -d '()'


    To delete the text and parentheses:



    sed 's/([^)]*)//g;s/ / /g'


    If the text contains nested parenthesis like :



    echo 'text0 (text1 (textA )) text2 (text3 text4) test5' |
     sed -e :A -e 's/([^()]*)//;tA' -e 's/ / /g'

                      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.
