Ubuntu :: Change Or Delete Obsolete System File Type

May 23, 2010

I use Markdown to store all of my source documents. Unfortunately, the .md extension maps to application/x-genesis-rom under Ubuntu. I'm not sure why that would be a system default MIME type, but I'd like to change it.

I've tried using:

Code:
gksu assogiate

to modify my file type cache. Unfortunately, even as the SU, I can't modify the entry for this file type. The "Remove" button is inactivated for the entry. (See attachment.)

How can I get rid of this (obsolete?) file association? Alternatively, how can I make my new one (text/x-markdown) take precedence?

Ubuntu :: Changing File System Type To Another Filesystem Type - Does It Effect On Data?

Feb 4, 2011

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5

previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal

After doing(changing the file system)this one ,i couldnt see the d:drive data

By doing that

1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.

2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.

Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)

I had very imp data in d:drive

Installation :: Change The Boot Partition - Error: Bad File Or Directory Type?

Jan 31, 2010

I have presently a (working) boot dedicated partition, where grub stuff resides, but I want to change it to a common "/boot" folder in the root partition (in a different hdd). For some reason I can't do it. The first thing I did was to copy all the things that are in the boot partition to a boot folder on the root partition. After that, I tried: grub-install /dev/hdc1 (which is odd but it's where the root partition actually is)

When I did it from the linux I have installed on my hdd, it actually did something, I don't remember all the output (except that there was something about it not being able to access hda, which is oddly the dvdrom), but it didn't work. From a live CD, the same command (grub-install /dev/hdc1) is answered with: Could not find device for /boot: Not found or not a block device. From grub's own prompt, the things are more or less the same. First of all, it does not find stage1, even though I did copy the content from the boot partition to a boot folder in the root partition.

I tried to proceed, anyway, with root (hd1,0) and setup (hd1,0) (which is /dev/hdc1, according with the "geometry" info given by grub). "Root" is accepted, but "setup" is answered with: Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... no Error 2: Bad file or directory type But the files are there. I can't "cat" the menu.lst from grub though, unlike with the actual working boot partition. The same error message. From the terminal, however, it's all there. I tried with /dev/hdc1 both mounted and unmounted, the same message. So, basically I have two questions, I guess:

1 - can I really do this sort of thing running a linux installed on a hdd, rather than a live cd, or is the live cd preferable for some reason?

2 - what am I missing?

(A note that may worth making is that I'm using the soon-to-be deprecated grub version, 0.9 or something, not grub2. I think it shouldn't be a problem since I've installed the system with the old version to begin with, but that may be irrelevant, I don't really know)

Feb 18, 2010

When I run 'parted' and then type 'print' to see the partitions that are available, I see two entries: /dev/sda1 and /dev/sda2. /dev/sda1 is of ext3 type whereas for /dev/sda2 nothing is specified for file system type. The LVM flags are set for /dev/sda2.

General :: Accidentally Type Concatenate Large File On Remote System

May 6, 2010

Every once in a while on a computer I'm ssh'd into, I will accidentally type "cat largefile.txt" and my screen will start rushing with text for the next 10 minutes. I'm always working in a screen session, so my current solution is to just log out and then log back in, and since it can go 100X faster when I'm logged out, it'll finish in the short time it takes me to type my password in again. Is there a better way? Either involving the fact I'm in a screen session? Or a way to do this within SSH? What doesn't work: detaching from the screen session (doesn't respond until file is done outputting) trying command to move to a different window in the screen session (also doesn't respond) typing ctrl+C to kill cat command (also doesn't respond, probably because the command is done and the buffers just have to catch up).

General :: GRUB Legacy - Unable To Determine The File System Type?

Dec 8, 2010

I had only Arch on an HDD.sda2 was "/".Now it's with Windows XP and sda2 is not a root any more but a container partition wich has sda{5,6,7} in it. I configured the dual boot and it works. It finds Arch and boots it, but not completely. Stops after some time and says: unable to determine the file system type of /dev/sda2. FSTAB is configured, sda{5,6,7} are on their places. So I can't boot Arch. XP boots correctly. What do I do with this error?Also it says: try adding rootfstype=your_filesystem_type to kernel command line.

Ubuntu Security :: Delete Files Off Journaling File-system?

Feb 19, 2010

I have some very confidental files on my computer that I store such as credit reports, and other things. I always encrypt them with GPG, but there still is that original non-encrypted file left that needs to be deleted. I looked into tools like wipe, and shred but they all say that it really doesn't help on journaling filesystems directly on their man page.

I am not asking how to wipe the whole drive with dd or anything, but I am simply asking if there is a tool that'll delete a single file securely.

General :: Ext4 New File System Mounting Compatibility With The Older Ext3 Type?

Sep 7, 2009

How well is the ext4 new file system mounting compatibility with the older ext3 previous Linux installations ? I refer to Ubuntu 9.04 and the new Fedora 11 which have the option to install with the ext4 file format. Will it be better if I install with the older ext3, so that I will be able to mount all other Linux from each other in a multi-boot system ?

I am figuring if I could somehow mount it onto a folder in my home partition I will have full permissions. The problem is the drives name which is exactly with space: So even if try to delete files in the terminal I don't know how to cd into:

Code:

General :: Cannot Change File Permissions On A Mounted File System

Apr 6, 2010

I have an ntfs partition that I wish to access as a normal user(non-root). For this I did the following. As root I created a folder /windows and did a chmod 777 -R on /windows. Then I added the following line to /etc/fstab

Code:

/dev/sda3 /windows ntfs-3g defaults,nosuid,nodev,umask=000 1 0

Now, the partition is mounted alright but the problem is that when any other user (non-root) creates a files in /windows (say by executing touch newfile) the newly created file has the owner and group set as root. The non-root user can create the file and he can also delete the file, however, he cannot change the permissions of the file and also the owner:group is always set as root:root. How do I get across this problem, i.e. how do I mount a partition, so that a non-root user can also change the permissions and ownerships of the files he creates.

Ubuntu :: "select File System Type"?

Oct 6, 2010

I split my partitions - root and home.In the installation of Ubuntu you can see the partition table if you edit it manually. You can see the partitions, devices, etc. What if I select the wrong file system on a partition I am not formatting? Example - if I format root but keep home, but home is EXT3 and I select EXT4 (or vice versa) what happens?
