New Computer

[etherial]

I've just got my new computer up and running. Pictures as soon as I have it in its final working place (macMinis are so awesome). Quick question, though. When we backed up the old computer, my brother set the data to "No Access". This is supremely annoying, because I have to manually change every folder to Read/Write in order to transfer the data. Is there any way in OS X (or *NIX) to reset it all to R&W?

chmod -R u+rw /topmost_directory

or

chmod -R u+rwx /topmost_directory

or

chmod -R u+rwx g+rx o+r /topmost_directory

depending on desired permissions... doubtless you get the picture.

So if I wanted to reset the permissions on a particular (non-system) drive, it would be?

the same thing only at the mount point.

I've never done anything in UNIX that involved multiple drives. You'll have to be a lot more specific.

Well, I usually start with just 'mount' or sometimes 'df' to see what's mounted where. Each drive partition is a system device. I expect you'll see things like /dev/hda0 where a is the physical drive and 0 is the partition number. It might be sda0 or hdb or some other variant, but you should be able to decipher it. So, you've figured out what the physical drive is, you can use the above commands to see that it's mount on /mount or /monkey or /thisdrive or whatever. 'df' is good here because it'll also tell you the partition sizes, to check against.

Now, just run the command as 'chmod -R u+rwx /mount'

I received about 1000 Permission Denied responses.

Are you logged in as root? Is root even enabled?

Re: from the command prompt

no.

Do so. If you don't really care about what users can see the drive change that chmod command from u+ to a+ (from only the user to all). Run as root, that should make it readable, no matter what.

sudo chmod worked.

There might be a way to make chmod recursive, in which case chmod [whatever recursive switch is] 777 would make it read/write/execute for everyone.

ok. Too slow. Sven's kung-fu is best.
