NAME

nproc — get processor count

SYNOPSIS

DESCRIPTION

Writes the number of available CPUs, followed by a newline, to the standard output stream. This can be modeled as max(sysconf(_SC_NPROCESSORS_ONLN) - IGN, 1).

OPTIONS

-a, --all

Writes the number of configured CPUs, which may be more than the available ones on some platforms. This corresponds to the _SC_NPROCESSORS_CONF sysconf(3) value.

-i, --ignore=IGN

Ignore (subtract) up to this many CPUs, if available (default 0).

SEE ALSO

sysconf(3)

STANDARDS

Compatible with the GNU system. The short flags are an extension.
