Yes, I know that's what disk copy does, but I'm wondering how it could be done from the command line, if it's possible at all.

>disktool

yup, possible. try hdiutil

edit: yeah, disktool should work too, but since hdiutil is documented, you can actually use it without any dangerous experimentation.

Couldn't you also use...
<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>
[localhost:~] theman% open -a /Applications/Utilities/Disk\ Copy.app/Contents/MacOS/Disk\ Copy /path/to/img
</font>[/code]
And just replace /path/to/img with the actual location of the image... I do this with Stuffit, and I assume it would work with Disk Copy, unless it isn't capable of handling this type of event...

I guess so, if you were feeling like typing or tabbing a lot!

Let "open -a" work its little bit of magic...

% open -a "disk copy" /path/to/img

Cheers,

using "Disk Copy" also assumes that you are logged into the Window Manager, so that Disk Copy can launch. Not a good assumption to make considering this is the Unix forum.

Thanks, I'll try hdiutil and disktool out.

Is there anyway to specify the dev-entry and mount point for a disk image? The man page for hdiutil is cryptic (aren't they all ) and doesn't seem to say anything about that.

Sorry to ressurrect a REALLY old thread, but I'd like to know the answer to this, too. Anyone know how to get a disk image to mount someplace other than /Volumes/ ? Thanks!

(This is my guess) I think, I think
you can change it in the /etc/fstab. Since
I have never actually tried editing or
even lookin into the fstab I don't know
if you can do it this way

I read the man pages and there doesn't seem to be a way to tell hdiutil or hdid where to mount the image. Also I had 3 fstab.xx files, all of which had a "This file is obsolete" comment at the top, I assume this info in in NetInfo now or something.

If you're interested though the hdid man page says how to create a RAM disk which I thought was interesting:

Code:
              hdid -nomount ram://<sectors>

       will attach a ram disk that can be mounted and used  after
       being  formatted with a newfs utility or Disk Utility.app.
       A sector is 512 bytes.

       A small shell script to create and mount a ram disk:

              #!/bin/sh

              NUMSECTORS=128000
              mydev=`hdid -nomount ram://$NUMSECTORS`
              newfs_hfs $mydev
              mkdir /tmp/mymount
              mount -t hfs $mydev /tmp/mymount

Do you suppose that it would be possible setup osx to create and mount a new ram disk at startup and then place the swapfile on the ramdisk?

That would qualify for most useless but cool idea of the month. I approve

Unless you have 4GB of ram or you don't use
wont run lots of program you will quicly run
into problems. (Remember what used to
happen in OS 9 when you ran out of memory
)
