Try this script:
Code:
#!/bin/ksh

if [ $# -ne 1 ]; then
        echo "usage: proc_tree.sh <pid>"
        exit -1
fi
pid=$1
while [ $pid -ne 1 ]; do
        ps -ef | nawk -v awkpid=$pid '{if($2==awkpid) print }'
        pid=$(ps -ef | nawk -v awkpid=$pid '{if($2==awkpid) print $3}')
done

This will print parent processes all the way to init.

kill.d

kill.d(1m)							   USER COMMANDS							kill.d(1m)

NAME

       kill.d - snoop process signals as they occur. Uses DTrace.

SYNOPSIS

       kill.d

DESCRIPTION

       kill.d is a simple DTrace program to print details of process signals as they are sent, such as the PID source and destination, signal num-
       ber and result.

       This program can be used to determine which process is sending signals to which other process.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       Default output, print process signals as they are sent.
	      # kill.d

FIELDS

       FROM   source PID

       COMMAND
	      source command name

       TO     destination PID

       SIG    destination signal ("9" for a kill -9)

       RESULT result of signal (-1 is for failure)

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       kill.d will run forever until Ctrl-C is hit.
