Slightly off topic but I'd use xargs for this approach e.g.
find $ORACLE_HOME -exec ls -ld {} >>exec_list \;
takes around 3 minutes on a Linux box I have whereas
find $ORACLE_HOME | xargs ls -ld >>xargs_list
produces the same results in 2 seconds
Cheers,
Ian

Sometimes a little bit of paranoia can be very healthy.
The simple answer is "rm -rf", as we have heard a few times already.
If you are paranoid (i.e., "careful") you could consider a two stage
approach similar to this:
# find /directory/to/be/deleted -exec ls -ld {} \;
# find /directory/to/be/deleted -exec rm -f {} \;
The first command lists EVERY file that is doing to be deleted, allowing
you to inspect the list and make sure there is nothing "bad" there.
The second command removes the files. (Actually, as written, it will
delete ONLY files, not directories, but this should give the idea.)
My preference is to use a command-line editor to change the first command
to the second, as that way I can be sure that the only difference is the
'ls' command versus the 'rm' command. The thing most likely to kill you is
going to be a mistype in the directory name, after all. Consider, for
example, the difference between "rm -rf ./*" and "rm -rf . /*" -- the
difference is only a single keystroke. And a bare-metal recovery.

I am nervous about doing this since it is Linux versus other OS. What is
the correct command to use to remove a directory and all of the files that
fall under that directory without receiving questions back about whether or
not want to remove various files within the that directory? In other
words, using the example below, I want to remove the
"directory_to_be_removed" including any files that are in it without having
to respond yes repeatedly? The directory being removed is actually
downloaded Oracle software from CD (but not the location where the install
of the software itself is actually located at).
/u04/db_files/directory_to_be_removed
