Well, what happens when you try this:
$ dd if=/dev/zero of=foo bs=1024 count=1
$ ls -l foo
-rw-rw-r-- 1 karsten karsten 1024 Nov 8 21:44 foo
$ cp foo /dev/null
$ ls -l foo
-rw-rw-r-- 1 karsten karsten 1024 Nov 8 21:44 foo
This isn't ancient Greece. We believe in the power of experiements and
scientific method.
No, copying a file to the null device doesn't remove the copy.
Moving a regular file to /dev/null will tend to produce various errors
when run as a nonprivileged user, and will clobber /dev/null when run as
root - don't do it.
What we're doing is first 'emptying' the file (catting /dev/null into
it), then removing a now-manageable, zero-byte file.
