FileUtils and "sudo"

Ruby
1

This is likely going to be a forehead slapper as soon as I ask… but
I’ll risk it.

I’ve written a general purpose utility for making backups and archives.
It does lots of nifty things, but at the core I end up using
FileUtils.cp_r. To date, I’ve used it with 1.8.6/.7 on MacOS X 10.6
without any problems.

Now, I’m running it on 10.7, and it seems that many FileUtils commands
get refused permission. AFAICT this is under the same general usage as
before. I don’t see anything different in the permissions hierarchy.
(This has me a little worried about eventually migrating many other
server/glue scripts I have which are not yet running on 10.7 servers.)

I’m having to resort to backticked CLI commands using sudo for now, but
that ruins the platform agnostics.

So two general questions:

  1. anyone know of Lion generally being different like this? I don’t see
    much chatter on the interpipes, so I’m thinking this may yet be
    something screwy on my system.

  2. regardless of OS, what’s the usual strategy for giving FileUtils
    sudo-level access for doing file commands?

Thanks.

assuming you currently have:
ruby my_script.rb

You should be able to :
sudo ruby my_script.rb

I think, I haven’t tried this
