What doe NR stand for ?



I've seen it used for (the local equivalent of) "number" in various countries.


Probably NumbeR.


Seems to be “normal resources”, where normal probably meant file descriptor based.


Where did you find that info ?

I am asking because I tried to write to basic nasm programs in order to learn and I used the c preprocessor (cpp) over my nasm files to take advantage of the libc macros from <sys/syscall.h> and they were all of the form __NR_syscall

Then the other responses' assumption, "NumbeR", seems correct


It's NumbeR. I don't have an authoritative source other than e.g. [0], but I was around (IRC, mailing lists) when some of these were created.

I’m wrong. Fourth paragraph from the bottom, last sentence they say “normal resource limits.” I thought that meant “the limit of something called normal resources” not the normal amount of the resource’s limit. Probably because I was trying to find out the exact same question as OP and thought that was it when I read it. I wish articles explained names more specifically sometimes…
