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.

Get it on your BlackBerry or iPhone.
