How can I parse a record found in /etc/passwd into variables?
I am working with the Oracle 10.2.0.3 job scheduler on Solaris 10, and unfortunately, the scheduler executes scripts in such a way that several default shell environment variables are not defined. For example, $HOME, $USER, and $LOGNAME are missing.

How can I parse the appropriate record in /etc/passwd into the above variables? For example, when the output from "grep oracle /etc/passwd" is:
oracle:x:100:1978::/usr/oracle:/bin/ksh
I need to parse the information so that I can manually export the following variables:
export HOME=/usr/oracle
export USER=oracle
export LOGNAME=oracle
I'm looking for something generic that will enable me to search for any record in /etc/passwd and parse it properly.

Thanks,

J

ICECREAM 
DAEMON(1)					      Icecream User's Manual						ICECREAM DAEMON(1)

NAME

       iceccd - Icecream daemon

SYNOPSIS

       iceccd [-n netname] [-m max_processes] [--no-remote] [-w] [-d | --daemonize] [-l logfile] [-s schedulerhost] [-v [v [v]]] [-r |
	      --run-as-user] [-b env-basedir] [-u | --nobody-uid nobodyuid] [--cache-limit MB] [-N hostname]

DESCRIPTION

       The Icecream daemon has to run on all nodes being part of the Icecream compile cluster. It receives compile jobs and executes them in a ch-
       root environment. The compile clients send their compile environment the first time they send a job to a particular daemon, so that the en-
       vironment of the daemon doesn't have to match the one of the client.

       The daemon also has to run on clients sending compile jobs to the Icecream network. If a node should be able to send compile jobs, but nev-
       er receive any, start the daemon with the option -m 0.

       All Icecream daemons need to have contact to the Icecream scheduler which controls the distribution of data between compile nodes. Normally
       the daemon will automatically find the right scheduler. If this is not the case you can explicitly specify the name of the Icecream network
       and the host running the scheduler.

OPTIONS

       -n netname
	      The  name  of  the icecream network the daemon should connect to. There has to be a scheduler running for the network under the same
	      network name.

       -m max_processes
	      Maximum number of compile jobs started in parallel on machine running the daemon.

       --no-remote
	      Prevents jobs from other nodes being scheduled on this one.

       -w

       -d, --daemonize
	      Detach daemon from shell.

       -l logfile
	      Name of file where log output is written to.

       -s scheduler_host
	      Name of host running the scheduler for the network the daemon should connect to. This option  might  help  if  the  scheduler  can't
	      broadcast its presence to the clients due to firewall settings or similar reasons.

       -v, -vv, -vvv
	      Control verbosity of daemon. The more v the more verbose.

       -r, --run-as-user
	      Force running the daemon with user rights. Usually you will need to run the daemon with root rights.

       -b env_basedir
	      Base directory for storing compile environments sent to the daemon by the compile clients.

       -u, --nobody-uid nobodyuid
	      Id of user nobody. This user id is used when the daemon is dropping privileges.

       --cache-limit MB
	      Maximum size in Mega Bytes of cache used to store compile environments of compile clients.

       -N hostname
	      The name of the icecream host on the network.
