psrinfo(1) General Commands Manual psrinfo(1) NAME
psrinfo, pinfo - Displays processor administration information SYNOPSIS
/usr/sbin/psrinfo -n /usr/sbin/psrinfo [-v] [processor...] /usr/sbin/psrinfo -s processor /usr/sbin/pinfo [-v] [processor...] OPTIONS
Displays the number of processors in the system. Enables verbose mode. Writes only a boolean value to standard output. The -s option requires a single processor identification number (processor). The -s option is intended to be used in scripts. A value of 1 is output if the specified processor is on line. A value of 0 is output if the specified processor is off line. DESCRIPTION
The psrinfo and pinfo commands display information about processors. The processor variable specifies the processor identification number, which is a unique integer that identifies the processor. If you do not specify any options or a processor identification number, the com- mands display information about all processors. EXAMPLES
The following is an example of the default prsinfo command output (no options or processor identification numbers): greene:> psrinfo 0 on-line since 11/03/1999 09:41:34 1 on-line since 11/03/1999 09:41:34 2 off-line since 11/03/1999 08:41:34 The following example shows how to use the psrinfo command with the -s option in a shell script to determine the state of the pro- cessor with an identification number of 1: if [ "`psrinfo -s 1 2> /dev/null`" -eq 1 ] then echo "processor 1 is up" else echo "processor 1 is down" fi The following example shows how to use the psrinfo command with the -v option: % psrinfo -v Status of processor 0 as of: 05/23/00 15:47:40 Processor has been on-line since 05/23/2000 15:08:04 The alpha EV5.6 (21164A) processor operates at 465 MHz, and has an alpha internal floating point processor. Status of processor 1 as of: 05/23/00 15:47:40 Processor has been on-line since 05/23/2000 15:08:04 The alpha EV5.6 (21164A) processor operates at 465 MHz, and has an alpha internal floating point processor. Status of processor 2 as of: 05/23/00 15:47:40 Processor has been off-line since 05/23/2000 15:08:04 The alpha EV5.6 (21164A) processor operates at 465 MHz, and has an alpha internal floating point processor. Status of processor 3 as of: 05/23/00 15:47:40 Processor has been on-line since 05/23/2000 15:14:00 The alpha EV5.6 (21164A) processor operates at 465 MHz, and has an alpha internal floating point processor.
