NAME

       pmhostname - report hostname


SYNOPSIS

       $PCP_BINADM_DIR/pmhostname [hostname]


DESCRIPTION

       pmhostname  reports  the  name  of  the  host  hostname as
       returned by gethostbyname(3N).

       If hostname is not specified, then the local host name  is
       retrieved  using gethostname(2) and this is than passed to
       gethostbyname(3N).

       pmhostname provides a service for shell scripts that  mim­
       ics  the  logic  used by Performance Co-Pilot applications
       when trying to determine the official name of a host.

       If gethostbyname(3N) fails, the input  host  name  (either
       hostname  or  the  result  from calling gethostname(2)) is
       reported.


PCP ENVIRONMENT

       Environment variables with the prefix  PCP_  are  used  to
       parameterize the file and directory names used by PCP.  On
       each installation, the  file  /etc/pcp.conf  contains  the
       local  values for these variables.  The $PCP_CONF variable
       may be used to specify an alternative configuration  file,
       as described in pcp.conf(4).
