I have come to know that we can use watch command to monitor the output of other command and it prints the output every 2 seconds by default, which is really useful.



I start to use it to monitor the output of nvidia-smi, for example. But now I do not know how to quit the program (stop monitoring the output of nvidia-smi). I tried to press q and there is no response.



Searching the internet with similar title gives me no clue. There are only some tutorials on how to use watch and its options and I can not find a way to stop the command. I am stuck here.




linux watch

          From man watch:




          By default, watch will run until interrupted.




          The key words are "until interrupted", which basically can be interpreted as until (but not limited to) the following happening:



          • The user (you) pressed CTRL+C in the terminal.

          • The system restarted.

          • The process was issued a kill request.

          • I am curious to know why there is no shortcut to use q to stop watching, just like when we are using less or man command. A lot of command support the use of q to quit.

          • I am not one of the programmers and I can not answer for them. As far as I understand, the source code for watch is available and you should be able to either fork it and create your own version that includes the option to press Q to quit or extend it like others have by submitting a patch or getting directly involved in the program development.

          • @Hao, note that reacting to a signal (generated by Ctrl+C) and reading tokens from stdin are very different code paths. less and man accept a variety of keystroke commands; q is just another among several. watch accepts no keystroke commands, so it would be functionality added only for quit.

                    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. What are those registers and how many are there? register x86-64 share | improve this...
