I would like to change the file content which i specified like below.I want to comment out all the lines which contains ".class" except the class name i provide.



@MyClass1.MyClass2(value = 
 Class1.class,
 Class2.class,
 Class3.class,
 Class4.class
)
public class Foo


For example if i provide Class2 as parameter to 



sed -i -E 's/some_regex/Class2/g'


command,the result should be like this,



@MyClass1.MyClass2(value = 
 //Class1.class,
 Class2.class,
 //Class3.class,
 //Class4.class
)
public class Foo


What regex should i use for this?






text-processing awk sed regular-expression

          For a file like this:



          $ cat file1
          @MyClass1.MyClass2(value = 
           Class1.class,
           Class2.class,
           Class3.class,
           Class4.class
          )
          public class Foo 
          @MyClass11.MyClass2(value = 
           Class1.class,
           Class2.class,
           Class3.class,
           Class4.class
          )
          public class Foo2


          You can have this result:



          $ sed '/@MyClass1.MyClass2(*/,/})/s' file1
          @MyClass1.MyClass2(value = 
           // Class1.class,
           Class2.class,
           // Class3.class,
           // Class4.class
          )
          public class Foo 
          @MyClass11.MyClass2(value = 
           Class1.class,
           Class2.class,
           Class3.class,
           Class4.class
          )
          public class Foo2


          Explanation:



          '/@MyClass1.MyClass2(*/,/})/ .... --> range to operate in form /from/,/to/actions



          to avoid escaping //






          share)/ .... --> range to operate in form /from/,/to/actions

          s)/ .... --> range to operate in form /from/,/to/actions



          sClass.*)/ .... --> range to operate in form /from/,/to/actions



          to avoid escaping //






          share)/s' file1
          @MyClass1.MyClass2(value =
          // Class1.class,
          Class2.class,
          // Class3.class,
          // Class4.class
          )
          public class Foo
          @MyClass11.MyClass2(value =
          Class1.class,
          Class2.class,
          Class3.class,
          Class4.class
          )
          public class Foo2


          Explanation:



          '/@MyClass1.MyClass2(*/,/})/ .... --> range to operate in form /from/,/to/actions



          {s|sClass.*|//&|g; --> apply // in all lines starting with whitespace s and then Class



          /Class2/ --> remove // for Class2



          Tip: In sed we can use any char as a separator for s/replacethis/withthat/ synthax.

          I choose | to avoid escaping //

          • Great answer,but i am just wondering, what if i want to apply // in all lines ending with .class? What regex should i use instead of {s|sClass.*|//&|g; ?

          • @aekber Maybe something like s|.class$|//&|g. The use of $ is a regex anchor that means "end of line".

          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...
