SUDO under Unix

[Cecylia]

I test to write an order under Unix (mac) which would include order SUDO (to have the privileges of Root)

but when I enter my order, he asks me my password on another line… I seek to create an achievable Script which would include my password on the same line that my SUDO.


Thank you to help me!

What the goal of the required operation?

[Cecylia]

The goal is to create a mac application which would carry out the order sudo umount - F

The problem, it is that when I test to make the application, it fail because the order sudo request the password admin on another line of order and as an application cannot ask for the line of order which requires the password of me, I would like to be able to enter the password the order itself!

Using hdiutil

The hdiutil program is a native Apple command line utility for working with disk images. It uses the DiskImages framework. Disk images (usually with a .dmg, .img, or .iso file name extension) are often used for distributing programs and for burning CDs/DVDs.

Creating a disk image from a folder

hdiutil create test.dmg -srcfolder /path/to/folder/

Once the disk image is created, it can be mounted, copied, or sent like any other file.

Mounting a disk image

To mount (or attach) a disk image, use:

hdiutil mount test.dmg

A mounted disk image appears on the Desktop, in the Finder, and shows up as a directory in /Volumes. All removable media, such as CDs, DVDs, external disks, and USB flash drives are mounted in /Volumes.

Unmounting a disk image

To unmount (or detach) a disk image, use:

hdiutil unmount /dev/device-name

The device name is usually something like /dev/disk3s2. You can also unmount it using the /Volumes/mountpoint if you know where it was mounted:

hdiutil unmount /Volumes/mountpoint

Burning an ISO to CD (or DVD)

First, load a blank CD, then:

hdiutil burn cd-image.iso

Create an encrypted disk image

This creates a 10 MB encrypted disk image and internally formats it as a journaled HFS+ file system (the OS X default):

hdiutil create -encryption -size 10m -volname encdata test.dmg -fs HFS+J

During the creation of the disk image, you will be prompted for a password that will allow access to the contents of the disk image. You must remember the password or anything you put into the image will be lost.

Solved problem…

I found the order without having rights SUDO

Opinion with the interested parties, the UNIX order to eject a volume under Mac is hdiutil /volumes/name of volume to be ejected - force


thank you
