Is there a way to completely restart Bash and reload .bashrc and .profile and the like? I'd like to make sure my changes worked out properly after editing these files.






bash bashrc source bash-profile

          Have it replace itself with itself.



          exec bash -l


          Note that this won't affect things such as the cwd or exported variables.

            Take out the exec and you get a shell that sources the files that you want. Then just exit when you are done checking.

          I urgently suggest to log in on a separate window/screen. This way you still have a working session if something goes wrong with your changes to startup files. Also you are sure to have a clean environment.



          Reason: I saw too many people locking themselves out of a system because of a simple typo in their .profile (or such).

          If your goal is simply to read the modified files again, you don't have to restart it. You can simply source it.



          source filename


          or 



          . filename # notice the dot


          Note that this won't give you a "clean state" in a sense that it won't unset any set variables or defined functions...

            su -l yourOwnUserName


            Will open a fresh shell for yourOwnUserName user with all the settings re-loaded. This is shell-independent, as it refers to system settings, not your specific shell. It also loads some system-wide settings that bash -l does not (like user groups).

            • important note: "a fresh shell" here means a shell within your existing shell, so you are only nesting shells, not replacing your original one. The accepted answer does that properly.

            If your goal is simply to read the modified files again, you don't have to restart it. You can simply source it.



            source filename


            or 



            . filename # notice the dot


            Note that this won't give you a "clean state" in a sense that it won't unset any set variables or defined functions...

                    su -l yourOwnUserName


                    Will open a fresh shell for yourOwnUserName user with all the settings re-loaded. This is shell-independent, as it refers to system settings, not your specific shell. It also loads some system-wide settings that bash -l does not (like user groups).

                    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...
