Hello all,

A script I have written needs the ability to move files. I thought I would =
be=20
clever and use File.rename(old, newdir + new) but this is giving me an erro=
r:=20
`rename': Invalid cross-device link. I gather this is because I am renaming=
=20
the file to a different partition.

So then I found FileUtils and used:
require 'fileutils'
include FileUtils
mv( old, new)

This is working but seems an overly verbose and convoluted way to move a fi=
le.=20
I had a look at the fileutils.rb source and found this (for 'mv'):
# Moves file(s) +src+ to +dest+.  If +file+ and +dest+ exist on the differe=
nt
# disk partition, the file is copied instead
=20
So I guess my real question is: is there a technical reason or some arbitra=
ry=20
reason there is no File.move() method that can handle this transparently? I=
=20
would think it would be quite useful...

Any insight is appreciated,
