Hi Viraj,
It looks to me like your clearing the value of $SHLIB_PATH (unset
SHLIB_PATH) then using $SHLIB_PATH to set the value of SHLIB_PATH. Since
it is empty to begin with the value will be null. In a shell script if you
run it from a user's current shell (in your case by executing tst) the
script picks up your current environment (therefore SHLIB_PATH is whatever
initial value is set from the user's .profile). But if you run . tst the
script gets it's environment from the script itself with all variables set
to null until initialized. You must make $SHLIB_PATH equal to some value
within the script before it can be used.
HTH,
Rocky
