Strange errors with shell scripts..plzz help

Hi all...

Please help me with this questions.
I am not good at shell scripting.

1) It seems like there are many ways that we can run the shell scripts.
what is the difference between each one?
is there any difference in executing the shell scripts in the above ways?
**** I am getting strange errors when i am executing the shell scripts *****

2) one of my shell script (very simple one).
It is working sometimes and it is throwing error some times.
The follwoing script works fine when i run it ./
and it throws error when i run it like .(space)./
(error ksh: ./[9]: here document `EOF' unclosed)

shell script:
sqlplus username/password@database << EOF > /lhome/xrmadm/bin/test1.log
set serveroutput on size 200000
whenever sqlerror continue
set echo on
exec dbms_output.put_line('$TEST_VAR');

The above script is creating a log file like this test.log? (i dont why that ""?"" is coming after running)

3)I have another script which is working
if i run it .(space)./

Thanks in advance...please help me with the above questions..

The use of .(dot to source) <shell script> is specifically used to initialize / update your environment and is called "source".

Hi alll ..

Thanks for the replies..

why the following script is creating log file with ""?"" at the end.
sqlplus username/password@database << EOF > /lhome/xrmadm/bin/test1.log
set serveroutput on size 200000
whenever sqlerror continue
set echo on
exec dbms_output.put_line('$TEST_VAR');

It is creating ""test1.log?"" file instead of ""test1.log""

is there any thing wrong that i am doing?
