NAME

psrinfo − displays information about processors

SYNOPSIS

psrinfo [ −v ] [ processor_id ... ]

psrinfo −s processor_id

DESCRIPTION

psrinfo displays information about processors. 

Without the processor_id operand, psrinfo displays one line for each configured processor, displaying whether it is on-line, off-line, or powered off, and when that status last changed.  Use the processor_id operand to display information about a specific processor.  See OPERANDS. 

OPTIONS

The following options are supported:

−s processor_id Silent mode.  Displays 1 if the specified processor is on-line, and 0 if the specified processor is off-line or powered off.
