"need ownership" on terminal eraseDisk command

I tried the following command in terminal upon some surplus backup cartridges to make them my own.
"diskutil eraseDisk HFS+ newdisk "/Volumes/1-Monthly"
I also tried the iteration using eraseVolume instead, and both times even while using an Admin account it told me I had to have ownership of the carts. They are read/writable iOmega Rev 35 gig devices and the single file on each of a half dozen carts are locked Retrospect backup files. I tried force-changing the extensions of the file, using Disk Utility (Gui AND Terminal), Techtool Pro 6, PPC and Intel machines I own, and leaving the cart on a large bass speaker magnet overnight. Then I tried a Lee Valley super magnet that is the same size as the cart and can lift a 7 lb chunk of metal. My hope was I get the "This disk is unreadable. Initialize?" warning message.
Dont care whats on them. Seller doesnt know any password for 'ownership'.
Waiting for Retrospect to get back to me via email with some hints, since a full working trial version of their app doesnt let me erase either.
Any Unix nerds out there can help? Ideas, hints?

Retrospect said this is not their software cause. Fine but I asked them for help to remove a locked Retrospect file, whether it needs unlocking before trashing or not doesnt matter to me.
Been on the forum at Lenovo who now handles the iOmega product line support and pretty much the same Unix commands. I tried it both with sudo and no sudo while in Administration control of my machine on both osx 10.5 and 10.7.x machines but still nothing.
I did wind up getting a full working trial copy of Retrospect for both OS's but that doesnt help.
Although the Finder's inspector window says its now formatted in Mac Extended format, it actually isnt. It is still not available for drag and drop or Time Machine access.
It does show up in Disk Utilities just once before I try force reformatting (erase is only available in the app, not format) with hopes this would work but it doesnt. Unix commands dont give me this response but the disk utility app does: "optical erase failed; not completed or completed with errors. See diskrecording.log (from in console) for more information"
Console app shows this error in more detail:
"Disk Utility: Erase started, Sat Oct 26 11:23:05 2013
Disk Utility: Erasing CD-RW media in Iomega RRD 83.B with generic profile via FireWire.
Disk Utility: Erase failed, Sat Oct 26 11:23:07 2013
Disk Utility: Erase sense: 5/20/00 Illegal Request, Invalid command operation code
Disk Utility: Erase error: 0x80020022 The device failed to respond properly, unable to recover or retry."
It does show up in Retrospect Express accessibility, but dislike the software so much I would prefer to not use it. Looks to me like the same interface and horrible GUI from the OS 9 days, when it was a pain to use too.
Pretty much out of ideas...

Where is the terminal "last" command getting it's information from?

I searching for the information that the terminal "last" command holds.
When I execute the "last' command...... I am seeing too little to be real..... something is up..... I need to determine when the information was deleted.
What log file is the last command using? In Mt. Lion, in Lion, in Snow Leopard?
Thanx for your help

For those who are reading this, this is about a Mt. Lion system with current patches 10.8.3
Thank you for the reply and the pointer to the audit directory.
I am continuing to ponder why last at the terminal is given unexpected behavior. I am now noticing the history in last is only for the "last" - no pun intended - 24 hours or there abouts on one of my systems. In the audit directory there are many more entries

Terminal & "periodic" command problem.

I noticed that my inactive memory was up to 8GB, so I decded to run "sudo periodic daily weekly monthly" to clean it out. It started, then almost immediately finished the task & I still had all that inactive memeory in use (with 365 MB free). Has periodic changed in the latest update or has it been munged and I need to reinstall terminal (or something else)?
Jyri

If that were true, it would be an incidental, undocumented side-effect that is, as such, not guaranteed to remain constant.
A few notes... first, note that you probably never actually need to run those three scripts. See [Five Mac Maintenance Myths|http://www.macworld.com/article/133684/2008/06/maintenance_intro.html].
Second, if you are not having some kind of performance issue, you should not be interpreting a high inactive memory number as a problem. Inactive memory should, under normal circumstances, be purged automatically when needed. Just ignore it
Third, if you are having performance issues, they may not have anything to do with the inactive memory numbers. You may or may not have memory problems - your issues might be caused by something completely different. Try looking at the [Mac OS X speed FAQ|http://www.index-site.com/Macosxspeed.html].

Sending Mail to Local Users via the Terminal mail Command

I am having trouble sending mail to other user account via the terminal mail command. It seems to work with some accounts i.e. guest, etc, but fails with others i.e. Dennis. It will fail with no error message. Has anyone had any experience using the unix mail command locally ?
Dennis

I don't know the answer to this but you might try the -v option on the mail command in order to get verbose output. Perhaps a useful message would pop up.
Also, you might consider posting this message in the Unix Forum. There is a good chance that someone there can help you with this issue.

Terminal rm command help needed

While looking for another problem on my Mac I had the Console open. I noticed quite a few messages involving something called Pogoplug*:

In Terminal I did a
sudo find / | grep pogoplug
and that returned lots of files with *pogoplug* as part of the filename.
Now what I need to learn is how to do a mass deletion of anything pogoplug related as I do not use this anymore and it seems to be clogging my system.
I tried a basic rm -R *pogoplug* but that didn't work. (unsurprising)
Please note that these files found by the find command turned up files on a couple of external drives as well, so what I'd like to do is totally delete anything with "pogoplug" in the file or directory name.
* I used the app Pogoplug a few months ago to evaluate a NAS setup. Pogoplug came with it. I had thought that I had deleted everything when I dragged the app to AppCleaner but apparently not.
Any help would be appreciated.
-Tod

I would absolutely not recommend trying to use the rm command to deal with this problem. It's too dangerous to mess around with unless you know exactly what you're doing.
Things like AppCleaner aren't very reliable for uninstalling complex software. You need to use the uninstaller provided by the makers of the software. They supply an uninstall script here:

I need to view the available commands and alias on my macbook. also i need to check system log history from terminal

I think I am missing some stuff in the commands. I need it to show a list of all available to me and alias ....any suggestions?
<Edited by Host>

rockymountainblues,
do you mean commands as in items in the Applications folder, or commands as in things that would be run from within Terminal? What sort of stuff do you think is missing from the commands?
By aliases, do you mean aliases within the shell that Terminal executes?
To check your system log history from Terminal, log in as an administrative user and go to /var/log. You should see several files with names that begin with system.log — the ones that end in .gz are inactive and compressed. The file named just system.log is the one that’s currently active.

Help needed with basic Terminal command

Hey there guys! Recently I decided to install SSD on my Mac Pro. Of course SSD is not spacious enough to store all my files, so I found a good solution on the web which involves a little bit of basic Terminal knowledge - http://mattgemmell.com/using-os-x-with-an-ssd-plus-hdd-setup/
In the article its said :
- In the Finder, copy the folder from SSD to the HDD. Check that it was copied successfully.
- In Terminal, 'cd' to the location of the original folder (on the SSD), and delete it via 'sudo rm -rf foldername'.
- in Terminal, still in the location of the original folder you just deleted, make a link to the copy of the folder on the HDD, via 'ln -s /Volumes/HDDname/path/to/foldername'.
What Im struggling with is what 'cd' means and what is meant by - 'still in the location of the original folder'?
I would appreciate if someone could explain to a noob how to create SDD+HDD setup mentioned in article.

cd means change directory.
- means options to the command follow.
The options listed for the Remove command are Recursive and Force.
Recursive means traverse all subdirectories and delete the files in there, too, then finish by deleting the listed directory. Force means do it no matter what.
still in the location of the original folder
means, don't change directories. You must be in the original folder's directory when you run the Link command as listed.
Some other options to your problem:
Move your entire Home folder (better): os x move home folder
Create your own Fusion Drive (sketchy): http://www.macworld.com/article/2014011/how-to-make-your-own-fusion-drive.html

Shell Script - Need to Open terminal and Print output?

Hi All,
I have a script to update a git version of a software, but I would like to be able to check the output of the script in a terminal.
So in a nut shell, I want when launching the script:
- Terminal to Open
- All command to be executed in the terminal
- Terminal to close only if no error (do not know if it's possible?)
See below my very simple script:

Terminal SSH commands

Hi,
I am experimenting with SSH using Terminal on Leopard. I have logged in to my remote server and have made changes to /etc/localdomains however I have no clue on how to save the changes. I tried 'command + S' but that saves it to local machine as a text file. Can you advice what command I need to use? Your help is much appreciated. thanks.

I don't see how anybody could find textedit faster than vi if you're familiar with vi. Your hands never have to leave the keyboard. If you're going to be doing much development on the Unix side it's well worth learning vi.

Terminal- Wrong command.

Earlier today I was trying to force-delete from my trash. But instead of
rm ~/.Trash/*
I typed in:
rm -rf ~/.trash /*
What happened next scared the lights out of me. It seemed that it was trashing everything/deleting everything but luckily most of the lines have said at the end "Permission Denied"
After that I checked my finder to see if my files and downloaded apps were still there, my finder for once, didn't know the size of any. But after a while it did.
Here's a 1/1500 of what happened in terminal.
Please, Answer quick
-Classified

Having put a space before "/*" directed the command to erase all files on your startup volume. Without the "sudo" command all system files would return the Permission Denied error. However, to be on the safe side I think you should reinstall Lion:
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Being asked for password using "boot to xp" terminal server command

I have XP partitioned on my Mac and I've always used a command shortcut I found on the internet that I put into terminal server called "boot to xp." I click on the alias I created, click "run" and it re-boots the system into xp.
Now, I click on the alias, click run, and I receive a prompt asking me for a password with a message stating "type your password to allow boot to xp to make changes."
I'm not sure what I've done to cause this but I'd like to turn it off. I had two accounts on this mac...one I use all the time and one called "admin." I never used the "admin" and had "admin rights" on this account so I deleted the one I called "admin" when this problem started. That didn't help.
Any suggestions? Thanks.

you know it's not a great idea to put your admin password in plain text form in the script. here is the script I use
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #ADD8E6;
overflow: auto;"
title="this text can be pasted into the Script Editor">
property target_username : ""
property target_userpassword : ""
property bootcamp_drive : ""
on open these_items
set bootcamp_drive to quoted form of POSIX path of (item 1 of these_items)
display dialog "Enter the name of an admin account as it appears in the Accounts menu:" default answer target_username
set the target_username to the text returned of the result
display dialog "Enter the password for that account:" default answer "" with hidden answer
set the target_userpassword to the text returned of the result
end open
on run
do shell script "bless -mount " & bootcamp_drive & " -legacy -setBoot -nextonly" user name target_username password target_userpassword with administrator privileges
tell application "System Events" to restart
end run</pre>
save it as an application.
first, drop the bootcamp drive onto the script You only need to do this once). it will prompt you for you admin name and password. now you can simply run the app to reboot into windows. the password will be stored in the script but at least it's not simply entered there in plain text form as you did. It's still possible to get the password out of my script too but it requires a bit more skill.

Terminal/UNIX commands reference

Hi there, I'm a beginner in using Terminal. I've searched all over the place but couldn't find a complete reference for the commands. Does one exist? Any ideas on the best reference(s)?
-Brett

Hi there, I'm a beginner in using Terminal. I've searched all over the place but couldn't find a complete reference for the commands. Does one exist? Any ideas on the best reference(s)?
Most likely not a complete reference.
Most commands are covered by 'man' pages (but not all).
man -k subject
can be used search available man pages.
I suppose
man -k " "
should give a list of all the commands.
And knowing the commands is not the same as knowing how to use them. You will need to find information on using the 'bash' shell, otherwise you are going to miss a lot.
'bash' is covered by "man bash", but again that does not tell you how to combine the commands to do useful work. In some ways, no book or web page can tell you that. Only using the commands in scripts while attempting to do real tasks will teach you those skills.

Terminal - Unix commands

Anybody knows of good tutorials or a manual for using the terminal to fire off unix commands, I have some unix experience, but I'm not sure what can be done with it on my MacBook - e.g. the yes test is a very good test and tool one can use to see how your system will react to a heavy load on the processor.
MacBook 2GHz, 1GB RAM Mac OS X (10.4.7)

You can also look at some books to help you out. Mac OS X Tiger in a Nutshell or Unix in a Nutshell from O'Reilly are good resources to use if you need to harness the power of the command line. I know because I use them daily, since I can't stand reading man pages off a computer screen....
Hope this helps

Need example vi using AT commands for dialing the modem at the remote end

Can any one give example vi for dialing up a modem and sending data to remote end

Hi sindhu6,
Presuming that you are connected to your modem via a serial connection:
I did find a forum related to your enquiry: http://forums.ni.com/t5/LabVIEW/AT-commands-in-labview/td-p/1213335
And I did find an example from ni.com: http://zone.ni.com/devzone/cda/epd/p/id/2577
Basically, what you need to do is to find out what are the AT commands used for your modem and send the command over using VISA related functions (e.g. VISA Read VI). You can send the command in a sequantial method. You can do this by using the method found in the first link. The best would be that you can create a state machine where by each case/state will consists of commands that you need to run in a sequence (let's say a sequence of AT commands for sending a message via TCP/IP communication).
You can also use a sequence structure but I would not suggest that since you cannot stop the sequence half way and if your command is very long, this may look pretty messy for your code.
The main question is:
What is the version of your LabVIEW?
What is the modem that you are using and how is your hardware setup is going to be (e.g. how did you communicate with your modem)?
Thank you
Warmest regards,
Lennard.C
