Suppose I do



 grep "MyVariable = False" FormA.frm

 ... result1

 grep "MyVariable = True" FormA.frm

 ... result2


How to write the grep command so that I can say something like



 grep "MyVariable = False" OR "MyVariable = True" FormA.frm





grep

  • You want to test whether a line contains Var1 = False AND Var2 = True? Or whether a file contains Var1 = False AND Var2 = True? Or something else? An example would help.

What you really want is "OR", not "AND". If "AND" is used, then logically, you'll get no lines (unless the line is something like "MyVariable = False...MyVariable = True".



Use "extended grep" and the OR operator (|).



grep -E 'MyVariable = False|MyVariable = True' FormA.frm

  • Incidentally, I noticed this works only with an uppercase "E" and not a lowercase "e". So grep arguments are case sensitive I suppose.

You should use



grep "MyVariable = (False|True)" FormA.frm


where the | sequence mean an alternative, and the delimiters ( and ) are for grouping.

    To answer in another way than what has already been said...



    You can also specify several matches to grep, by specifying the -e option several times



    % grep -e "MyVariable = True" -e "MyVariable = False" FormA.frm
     ... result1
     ... result2

            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...
