I'm trying to create a compressed TAR file. I have a disk that I am going to destroy and would like to take one last snapshot of the /users folder but don't want the users .m4v .m4a and .mp3 files as they are too large.

I tried using this command line

sudo tar acvf- -exclude='*.m4v' -exclude='*.m4a' -exclude='*.mp3' /home/john/Desktop/KS_UserFolders.tar.gz media/john/OS/Users/

The message that I get back is 

john@Pepper:~$ sudo tar acvf- -exclude='*.m4v' -exclude='*.m4a' -exclude='*.mp3' /home/john/Desktop/KS_UserFolders.tar.gz media/john/OS/Users/
[sudo] password for john:
tar: -exclude=*.m4a: Cannot stat: No such file or directory
tar: -exclude=*.mp3: Cannot stat: No such file or directory
tar: Removing leading `/' from member names
tar: /home/john/Desktop/KS_UserFolders.tar.gz: Cannot stat: No such file or directory
tar: media/john/OS/Users: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
john@Pepper:~$

I'm sure it's just me getting used to the syntax of Linux, but I can't find a good usage example of TAR that matches my situation, and version of TAR

command-line

So my Ubuntu 15.04 was working fine. Then I used clonezilla to backup the OS partition to a USB external disk. Installed a new 1tb disk, then booted using a 15.04 Live USB disk and restore the image. I then resized the partition using Gparted, and created a swap partition that was 16GB (I have 8GB of RAM on my lappy) The first couple reboots worked fine and I was proud of myself of conquering this project like a boss. Then I rebooted and got this error

error: invalid magic number

error: you need to load the kernel first

Press any key to continue

After that I am returned to the grub menu. I can boot from the 3rd option down as illustrated in the picture.

enter image description here

When I boot from the 3rd option, everything looks normal. I am new to grub tinkering, but would like my system to boot like it previously did.....automatically.

Thanks!

I am novice Ubuntu user. For laughs I encrypted an external USB drive and put a punch of secret stuff on it. It used to be that every-time I would attach the drive I would be challenged for a password. At some point I inadvertently clicked "remember password" and now the volume mounts automagically.

How can I remove the cached password so I will be asked for a password each time I mount the volume?

Thanks!

After upgrading my host to 12.04 I can no longer connect to Windows Shares in my AD (Active Directory) based network. I was able to do it previously using 11.10. I thought it might be an issue with the upgrade so I flattened my box and re-installed from scratch and I still can't connect.

When I use the Files>Connect to Server command, I am met with a constant password challenge when accessing any windows server using any known working network account.

I checked the logs on the windows machine to see if there are failed connections but there are none, yet 12.04 asks me for my password over and over as if my credentials were wrong.

Any suggestions?
