Bash script to read a hostname and separate into variables
Hi All,

I'm trying to concoct a bash script to use with a Puppet Implementation that will accept a hostname and break it down into variables.

For example, my hostnames look like this --> machinename-group-building.example.com

I'm looking for a way in the script to read until the first hypen (run it like --> "/usr/bin/hostnamescript machinename-group.building.example.com"), and assign the "machinename" into a variable, read to the second hyphen and assign the "group" into a variable, and then read until the period and assign the "building" into the final variable - disregarding the rest.

What would be the easiest way to tackle this? Thanks!

hobbitclient.cfg

HOBBITCLIENT.CFG(5)						File Formats Manual					       HOBBITCLIENT.CFG(5)

NAME

       hobbitclient.cfg - Xymon client environment variables

DESCRIPTION

       Xymon  programs	use  multiple environment variables beside the normal set of variables.  For the Xymon client, the environment definitions
       are stored in the ~xymon/client/etc/hobbitclient.cfg file.  Each line in this file is of the form NAME=VALUE and  defines  one  environment
       variable NAME with the value VALUE.

SETTINGS

       BBDISP The IP-address used to contact the Xymon server. Default: Chosen when the Xymon client was compiled.

       BBDISPLAYS
	      List  of	IP-adresses  of  Xymon	servers.  Data	will  be  sent	to  all  of  the servers listed here. This setting is only used if
	      BBDISP=0.0.0.0.

       BBPORT The portnumber for used to contact the Xymon server.  Default: 1984.

       BBHOME The Xymon client top-level directory. Default: The $HOBBITCLIENTHOME setting inherited from the "runclient.sh" script  which  starts
	      the Xymon client.

       BBCLIENTLOGS
	      The directory for the Xymon clients' own logfiles. Default: $BBHOME/logs

       BBTMP  Directory used for temporary files. Default: $BBHOME/tmp/

       BB     Full path to the bb(1) client program. Default: $BBHOME/bin/bb.

       Commands
	      Many extension scripts expect a series of environment variables to point at various system utilities. These are included in the file
	      when the client is built.

INHERITED SETTINGS

       Some environment variables are inherited from the "runclient.sh" script which launches the Xymon client:

       MACHINEDOTS
	      The hostname of the local system. Default: Taken from "uname -n".

       MACHINE
	      The hostname of the local system, with dots replaced by commas.  For compatibility with Big Brother extension scripts.

       BBOSTYPE
	      The operating system of the local system, in lowercase. Default: taken from "uname -s".

       HOBBITCLIENTHOME
	      The top-level directory for the Xymon client. Default: The location of the "runclient.sh" script.
