pmhostname

PMHOSTNAME(1)						      General Commands Manual						     PMHOSTNAME(1)

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 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(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 configura-
       tion file, as described in pcp.conf(5).

SEE ALSO

       named(1), nsd(1), nslookup(1), gethostname(2), gethostbyname(3N), pcp.conf(5), pcp.env(5) and resolver(5).
