Passing variables from shell script to separate sqlplus script

Question

Hi, I am having issues passing variables to a separate sqlplus script invoked by the shell script, e.g.
#!/bin/sh
DB_NAME=TEST
PWD1=PA55W0rd
echo exit | sqlplus / as sysdba @${DB_NAME}.sql ${DB_NAME} $PWD1 >> ${DB_NAME}.sql
exit 0
The script picks up the $DB_NAME variable fine, and therefore invokes the required sql script.
However, when I pass the variable $PWD1 to the sql script I get an error.
The script creates a database link:
create or replace procedure new.link
is
begin
execute immediate 'create database link TEST
connect to TESTSCH identified by '$PWD1'
using ''TEST''';
end;
exec new.link;
output is:
ERROR at line 1:
ORA-00911: invalid character
ORA-06512: at "NEW.LINK", line 4
ORA-06512: at line 1
any help appreciated!

I went to the documentation:

I searched for "sqlplus" which gave me this documentation (under "SQL*plus program syntax")...
http://docs.oracle.com/cd/E11882_01/server.112/e16604/ch_three.htm#i1169374
I read the syntax:
SQLPLUS [ [Options] [Logon|/NOLOG] [Start] ]and the subsequent information:

Start
@} [arg ...]
Specifies the name of a script and arguments to run. The script can be called from the local file system or from a web server.
SQL*Plus passes the arguments to the script as if executing the file using the SQL*Plus START command. If no file suffix (file extension) is specified, the suffix defined by the SET SUFFIX command is used. The default suffix is .sql.
See the START command for more information.

Data items you wish to pass to parameters in the script. If you enter one or more arguments, SQL*Plus substitutes the values into the parameters (&1, &2, and so forth) in the script. The first argument replaces each occurrence of &1, the second replaces each occurrence of &2, and so on.

Your script was including a Unix style substitution, not an SQL*Plus script substitution, so that's seems to be the most likely cause of your problem.
And still you haven't come back to say whether it's worked for you or not... leaving others guessing as to whether you still need help.
