I wish to delete some text before some pattern. For example:



VAR="This is a test script text and real script text."
PATTERN="test "


And the desired output that I want is:



NEW_VAR="script text and real script text."


Please kindly advise me as I am new to Linux scripting.

          If you are using a shell that supports parameter expansions of type $WORD##*STR, then all you need to do is below.



          printf '%sn' "$VAR##*$PATTERN"


          To store it in the new variable, use the command substitution trick with $(..) or use printf's inherent capability to store the formatted string in a new variable



          printf -v NEW_VAR '%s' "$VAR##*$PATTERN"

                    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...
