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

You rock!

Another question: how can I spool this in file like this:
echo "DATAFILE" >> controlfile.sql
echo "`ls /ebsprod_c/oradata/*.dbf | sed -e '/log0.*/d' -e "s#.*#'&',#" -e '$s#,$##''`" >> controlfile.sql
echo "CHARACTER SET AL32UTF8;" >> controlfile.sql

no need of echo....
Code:
echo "DATAFILE" >> controlfile.sql
ls /ebsprod_c/oradata/*.dbf | sed -e '/log0.*/d' -e "s#.*#'&',#" -e '$s#,$##' >> controlfile.sql
echo "CHARACTER SET AL32UTF8;" >> controlfile.sql

echo "CHARACTER SET AL32UTF8;" >> controlfile.sql

That works as well!!!

One step further: let's say I want to replace prod with another value like test (so it has to read from /ebsprod_c/oradata, but the spooled output should be like /ebstest/oradata)?

I'm learning a lot here... You guys are awesome.

YMMV:
Code:
sed -e '/log0.*/d' -e 's#prod_c#test#' -e "s#.*#'&',#" -e '$s#,$##'

Thank you guys.
