NAMEpmhostname - report hostname
SYNOPSIS
$PCP_BINADM_DIR/pmhostname [hostname]
DESCRIPTIONpmhostname 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
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).
SEE ALSOnamed(1), nsd(1), nslookup(1), gethostname(2), gethostbyname(3N),
pcp.conf(4), pcp.env(4) and resolver(4).
