== Introduction ==

 The purpose of this page is to develop and introduction to using DVO from the complete perspective of a new non-astronomer user.


== Logging into IPP and starting DV0 ==

 * Step 1) You need to do is log into an IPP machine that runs DVO. Example below:

{{{
$ssh -X -p 9005 ipp5u
}}}
  '''Note:''' There is an X windows session and the port is 9005 and the machine ipp5u is only accessible internally to the cluster.
  If you need to ssh from an outside machine, see [http://ps1wiki.ifa.hawaii.edu/trac/wiki/IPPssh sshing]. 

 * Step 2) Setup your psconfig to setup your ps lib configuration.  Example below
{{{
$psconfig --list
PSCONFDIR : /home/panstarrs/ipp/psconfig
  Archives   : Archives
  lin64      : ipp-20120216
  lin64      : ipp-20120404
  lin64      : ipp-20120531-debug
  lin64      : ipp-20120531
  lin64      : ipp-eam
  lin64      : ipp-trunk
  bash       : psconfig
  csh        : psconfig
$psconfig ipp-20120531
}}}

 * Step 3) Launch DVO
{{{
$dvo
}}}


== Getting Started with DVO ==

 If you have successfully launched dvo you will be see the dvo prompt.  Several useful commands:
  * '''??''' - Gives all the system environment variables available (i.e., HOME, PID, etc).
  * '''?''' - Shows all the available dvo commands .
  * ''' ! ''' - Gives the ability to execute systems commands. Example: 

{{{
dvo: ! echo "Hello World"
Hello World
}}}
