NPROC(1) FreeBSD 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 specified.
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.
