Need help with a sh script to spool directory and modify the output (Oracle cnt file)

Hi,

I'm creating a shell script to dynamically create a recreate controlfile for an Oracle database. I need to read a cold backup file system, and make some changes to these files.

Let's say for argument sake the directory name is /ebsprod_c/oradata and it looks like this:
/ebsprod_c/oradata/ctxd01.dbf
/ebsprod_c/oradata/discoverer01.dbf
/ebsprod_c/oradata/log01.dbf
/ebsprod_c/oradata/log02.dbf
/ebsprod_c/oradata/undo01.dbf
/ebsprod_c/oradata/undo02.dbf
/ebsprod_c/oradata/undo03.dbf
/ebsprod_c/oradata/undo04.dbf
/ebsprod_c/oradata/undo05.dbf

What I need is to:
a. exclude the log0* files
b. Add a apostrophe and a comma to each line, except the last line which should only have a apostrophe to make it look something like this:
'/ebsprod_c/oradata/ctxd01.dbf',
'/ebsprod_c/oradata/discoverer01.dbf',
'/ebsprod_c/oradata/undo01.dbf',
'/ebsprod_c/oradata/undo02.dbf',
'/ebsprod_c/oradata/undo03.dbf',
'/ebsprod_c/oradata/undo04.dbf',
'/ebsprod_c/oradata/undo05.dbf'

I figured out how to spool the files and add the apostrophe and comma:
for dirname in $(ls /ebsprod_c/oradata/*.dbf)
do
filename=$(echo $dirname)
echo "'$filename'," >> datafiles.tmp
done

But I can't figure out how to remove/exclude the comma from the last line and how to exclude the log0* files.

Any help would be appreciated!

Thanks!
Mark

OCI_SET_CLIENT_INFO(3) OCI_SET_CLIENT_INFO(3) oci_set_client_info - Sets the client information SYNOPSIS
bool oci_set_client_info (resource $connection, string $client_info) DESCRIPTION
Sets the client information for Oracle tracing. The client information is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement is executed. The client information can subsequently be queried from database administration views such as V$SESSION. The value may be retained across persistent connections. PARAMETERS
o $connection -An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3). o $client_info - User chosen string up to 64 bytes long. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Setting the client information <?php $c = oci_connect('hr', 'welcome', 'localhost/XE'); // Record the client information oci_set_client_info($c, 'My Application Version 2'); // Code that causes a roundtrip, for example a query: $s = oci_parse($c, 'select * from dual'); oci_execute($s); oci_fetch_all($s, $res); sleep(30); ?> // While the script is running, the administrator can see the client // information: sqlplus system/welcome SQL> select client_info from v$session; NOTES
Note Oracle version requirement This function is available when PHP is linked with Oracle Database libraries from version 10 g onwards. Tip Performance With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO pack- age. This is less efficient than using oci_set_client_info(3). Caution Roundtrip Gotcha Some but not all OCI8 functions cause roundtrips. Roundtrips to the database may not occur with queries when result caching is enabled. SEE ALSO
