Passing string from SQL to a BASH script
OS Solaris 10,
DB oracle 10g

Hello,
We currently have a BASH script that runs and moves image files from a remote server to the local db server. A snippet of the code shows that we are picking up all Images that are 'mtime -1'

Code:
some code...
for file in `ssh user@10.200.200.10 'find /u01/bea/madeup/Images -name "*.jpeg" -mtime -1'`
do
scp user@10.200.200.10:${file} /oraworking/madeup/images/orig/
done
...more code

It's simple and it works.

Now, due to development requirements we need a way of picking up those images from different directories within the base directory of /u01/bea/madeup/Images. The plan is to have an 'index' table that will hold the location (path and filename) of the image file and it is this that I would like to read from the table and somehow use in place of the hard coded file path above.
Can I Just do something like this example: (This may work with some tweaking, but it gives you an idea of what i am trying to achieve).

Code:
for file in `ssh user@10.200.200.10 'find /oracle/product/db/10gR2/bin/sqlplus -s /nolog  <<EOF  #Find is just going to try and find something in '/oracle/product/db/10gR2/bin/sqlplus' so this is wrong!

conn / as sysdba

set heading off
set feedback off
set pagesize 0
set linesize 30000
set trimout on
SELECT f.file_path||'/'||f.file_name
FROM fileupload f
INNER JOIN imagelog i
ON f.id = i.fileupload_id;'

EOF`

do
if [ -f ${file} ]
then
        echo "Skipping $file file..."
continue
fi

scp user@10.200.200.10:${file} /oraworking/madeup/images/orig/

done
...more code

Thanks in Advance,

Jonathan

       DESCRIPTION

       By  default,  the  bld  daemon  listens to requests on port 2905.  Requests are either IP addresses submissions or checks against the black
       list.

       bld uses a very simple algorithm to decide whether to add IP addresses to the blacklist or not. The first time an IP address is	submitted,
       it  is  added  to  an internal list with a timestamp and all further requests increment a counter for this IP.  As soon as the minimum time
       interval is elapsed (default: 30 seconds), and if a maximum requests ratio is reached (default: 10 submissions in the 30 seconds interval),
       the IP is put in the blacklist.	It is then blacklisted for a configurable time (default: 900 seconds).

PROTOCOL

       Requests sent to bld are rather simple.	Each request or reply is followed by a linefeed and a carriage return.	A client may only send one
       request per TCP session.  As of now, two commands may be used: ip (address submission) and ip? (ask if address is blacklisted).

       ip=a.b.c.d submits an IP address.  The server acknowledges either with a 200 code if the address is not blacklisted or a 421 if it is.

       ipdecr=a.b.c.d decrements the internal counter for an IP address.  The lowest value for the counter is zero.  The  server  always  acknowl-
       edges with a 200 code.

       ip?=a.b.c.d asks if address is blacklisted.  The server reply may be 421 if it is or 200 if it's not.

       ipbl=a.b.c.d forces the insertion in the blacklist.  The server acknowledges with a 200 code.

       If  using IP based restrictions, the server reply may be 600 if the client is not in the correct ACL to perform a request.  Any other error
       will generate a reply with a 500 error code.

NOTES

       bld binds to localhost by default and accepts any local request, so please make sure that only trusted users can establish a connection	to
       the  daemon.  Please check that all authorized hosts meet the minimal security requirements before changing this parameter even if using an
       access control list (see bld_acl.conf(5)).

       bld will log some statistics if it receives the SIGUSR1 signal.	SIGUSR2 is used to force a dump of both lists in bld working directory.

FILES

       /etc/bld/bld.conf      /etc/bld/bld_acl.conf	 /etc/bld/bld_whitelist.conf	   /var/run/bld/bld.pid       /var/run/bld/bld_iplist.dump
