Just a quick update on my "rm" failure...

1: EXT3 filesystem does automatically overwrite the first sector or two of a
file.  Apparently this is part of the EXT3 spec.

2: I ended up using the "dd if=/dev/sda6 | strings | less" command and
copy-and-paste the small shell scripts I was looking for.  The only drawback
to this is that "less" tries to buffer everything, and I couldn't determine
a way to tell it to only save the last 2MB of the buffer.  I ended up having
to do some more steps to narrow down the region of the disk...

Sadly in my case the scripts I was looking at were pretty small, so I didn't
get back my latest revisions due to the "overwrite first sector" feature.
Oh well, live and learn to make better backups...
