Hi,
I am using the HP-UX machine of version B.11.23. My bashprofile looks like this :

# @(#)B11.23_LR
# Default user .profile file (/usr/bin/sh initialization).
#! /usr/bin/bash
# Set up the terminal:
if [ "$TERM" = "" ]
then
eval ` tset -s -Q -m ':?hp' `
else
eval ` tset -s -Q `
fi
stty erase "^H" kill "^U" intr "^C" eof "^D"
stty hupcl ixon ixoff
tabs
# Set up the search paths:
PATH=$PATH:.
# Set up the shell environment:
set -u
trap "echo 'logout'" 0
# Set up the shell variables:
EDITOR=vi
export EDITOR
exec /usr/local/bin/bash

# Netezza4.5
export SHLIB_PATH=$SHLIB_PATH:/home/Netezza/lib:/usr/local/lib
export PATH=$PATH:/home/Netezza/bin:/usr/local/bin

when i check the env variables, using env command, i am not able to see SHLIB_PATH.

i.e. if i give echo $SHLIB_PATH, it is showing the blank path
and $PATh is not showing the path mentioned in the bashprofile

If i remove the line "exec /usr/bin/bash", then i am able to see the $path in env but when i am sourcing the bashprofile, it is showing that $SHLIB_PATH : unbound variable

Please help me regarding this.
