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

checkbashisms

CHECKBASHISMS(1)					      General Commands Manual						  CHECKBASHISMS(1)

NAME

       checkbashisms - check for bashisms in /bin/sh scripts

SYNOPSIS

       checkbashisms script ...
       checkbashisms --help|--version

DESCRIPTION

       checkbashisms, based on one of the checks from the lintian system, performs basic checks on /bin/sh shell scripts for the possible presence
       of bashisms.  It takes the names of the shell scripts on the command line, and outputs warnings if possible bashisms are detected.

       Note that the definition of a bashism in this context roughly equates to "a shell feature that is not required to be supported  by  POSIX";
       this means that some issues flagged may be permitted under optional sections of POSIX, such as XSI or User Portability.

       In  cases  where  POSIX	and  Debian  Policy  disagree, checkbashisms by default allows extensions permitted by Policy but may also provide
       options for stricter checking.

OPTIONS

       --help, -h
	      Show a summary of options.

       --newline, -n
	      Check for "echo -n" usage (non POSIX but required by Debian Policy 10.4.)

       --posix, -p
	      Check for issues which are non POSIX but required to be supported by Debian Policy 10.4 (implies -n).

       --force, -f
	      Force each script to be checked, even if it would normally not be (for instance, it has a bash or non POSIX shell shebang or appears
	      to be a shell wrapper).

       --extra, -x
	      Highlight lines which, whilst they do not contain bashisms, may be useful in determining whether a particular issue is a false posi-
	      tive which may be ignored.  For example, the use of "$BASH_ENV" may be preceded by checking whether "$BASH" is set.

       --version, -v
	      Show version and copyright information.

EXIT VALUES

       The exit value will be 0 if no possible bashisms or other problems were detected.  Otherwise it will be the sum of the following error val-
       ues:

       1      A possible bashism was detected.

       2      A file was skipped for some reason, for example, because it was unreadable or not found.	The warning message will give details.

SEE ALSO

       lintian(1).

AUTHOR

       checkbashisms  was originally written as a shell script by Yann Dirson <dirson@debian.org> and rewritten in Perl with many more features by
       Julian Gilbey <jdg@debian.org>.
