6 pmhostname - report hostname

9 pmhostname [-?] [hostname]
10
12 pmhostname reports the name of the host hostname as returned by geth‐
13 ostbyname(3).
14
15 If hostname is not specified, then the local host name is retrieved us‐
16 ing gethostname(2) and this is than passed to gethostbyname(3).
17
18 pmhostname provides a service for shell scripts that mimics the logic
19 formerly used by Performance Co-Pilot applications when trying to de‐
20 termine the official name of a host. PCP applications no longer use
21 DNS-based heuristics, and therefore this command is deprecated.
22
23 If gethostbyname(3) fails, the input host name (either hostname or the
24 result from calling gethostname(2)) is reported.

27 The available command line options are:

29 -?, --help
30 Display usage message and exit.
31
33 Environment variables with the prefix PCP_ are used to parameterize the
34 file and directory names used by PCP. On each installation, the file
35 /etc/pcp.conf contains the local values for these variables. The
36 $PCP_CONF variable may be used to specify an alternative configuration
37 file, as described in pcp.conf(5).
