PMHOSTNAME(1)            General Commands Manual           PMHOSTNAME(1)

NAME         top

       pmhostname - report hostname

SYNOPSIS         top

       pmhostname [-?]  [hostname]

DESCRIPTION         top

       pmhostname reports the name of the host hostname as returned by

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

       pmhostname provides a service for shell scripts that mimics the
       logic formerly used by Performance Co-Pilot applications when
       trying to determine the official name of a host.  PCP
       applications no longer use DNS-based heuristics, and therefore
       this command is deprecated.

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

OPTIONS         top

       The available command line options are:

       -?, --help
            Display usage message and exit.


       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
