psrinfo displays information about processors.

Without the processor_id operand, psrinfo displays one line for each configured processor, displaying whether it is on-line, non-interruptible (designated by no-intr), 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.

The following options are supported:

-s processor_id

Silent mode. Displays 1 if the specified processor is fully on-line, and 0 if the specified processor is non-interruptible, off-line, or powered off.

Use silent mode when using psrinfo in shell scripts.

-v

Verbose mode. Displays additional information about the specified processors, including: processor type, floating point unit type and clock speed. If any of this information cannot be determined, psrinfo displays unknown.

The following operands are supported:

processor_id

The processor ID of the processor about which information is to be displayed.

Specify processor_id as an individual processor number (for example, 3), multiple processor numbers separated by spaces (for example, 1 2 3), or a range of processor numbers (for example, 1-4). It is also possible to combine ranges and (individual or multiple) processor_ids (for example, 1-3 5 7-8 9).

The following exit values are returned:

0

Successful completion.

>0

An error occurred.
