Is this segment fault raised when running `shuf`?

I have a script, where there is a line:



eval for i in "$1".."$2"; do [ ! -e "$3"/$i.* ] && echo "$i" ; done | shuf | mycommand "$3"


which means: first create a sequence of numbers, pipe them to shuf, and then pipe them to mycommand.



Most of time the script runs fine, but sometimes it gets segment fault error



/home/tim/bin/myscript: line 25: 10170 Exit 1 for i in 0001..734;
do
 [ ! -e XMJ/$i.* ] && echo "$i";
done
 10171 Done | shuf
 10172 Segmentation fault (core dumped) | mycommand XMJ


Does that mean that the segment fault is raised when running shuf?



What can we deduce from the error message and possibly correct it?



Thanks.

          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...
