True. But no harm in getting it off the ground quickly before optimising. Git was written in Perl originally, and ported bit by bit to C. I think this shows it can be a good way to work -- prototype quickly, then optimise.

As pointed out elsewhere, this functionality already exists in Unix userland tools, like `rm -P` or (for GNU) `shred`.

This. You can bicker all day long about the "correct" language to write something in but at the end of that long day of going back and forth nothing actually got written. Better to go with what you know and prototype then weigh the benefits of rewriting/refactoring it in another language/toolchain.

Except, of course, when it is already written and people are just ignorant of tools that have been around for many many years.
