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 ...]
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 flags or a processor identification number, the commands
display information about all processors.
FLAGS
Displays the number of processors in the system. Enables verbose mode.
Writes only a boolean value to standard output. The -s flag requires a
single processor identification number (processor). The -s flag is in-
tended 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 proces-
sor is off line.
EXAMPLES
The following is an example of the default prsinfo command output (no
flags or processor identification numbers): processor 0 online
since 09/15/1994 17:24:30 processor 1 offline since 09/16/1994
09:18:22
The following example shows how to use the psrinfo command with the -s
flag in a shell script to determine the state of the processor 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"
