NPROC(1)		    General Commands Manual		      NPROC(1)

NAME
       nproc --	print the number of processors

SYNOPSIS
       nproc [--all] [--ignore=count] nproc --help nproc --version

DESCRIPTION
       The  nproc utility is used to print the number of processors limited to
       the cpuset(2) of	the current process, unless the	--all flag  is	speci-
       fied.

       The available flags are:

       --all   Count all processors currently online.

       --ignore=count
	       The result is decreased by count, but never below 1.

       --version
	       Print  the  current  program version and	exit.  Do not use this
	       option.

       --help  Print usage information and exit.

COMPATIBILITY
       This program is intended	to be compatible with nproc as	found  in  GNU
       coreutils.

BUGS
       If  HyperThreading  is  enabled in BIOS and disabled in the kernel, the
       --all option on Linux will still	report all possible CPU	 threads.   On
       FreeBSD only active threads will	be reported.

SEE ALSO
       cpuset(1)

HISTORY
       The nproc utility first appeared	in FreeBSD 13.2.
