The cd command is used to change the current directory zero cd linux. The items in square brackets are optional. When used without specifying any directory name, cd returns the user to the previous current directory. This provides a convenient means of toggling between two directories. When a directory name is provided, cd changes the current directory to it. The name can be expressed as an absolute pathname i.
It is usually more convenient to use a local pathname when changing to a zero cd linux of the current directory. As an example, the following would change the current directory, regardless of where it is on the system because it is an absolute pathto the root directory which is represented by a forward slash:.
On Unix-like operating systems the current directory is represented by a single dot and its parent directory i. Thus, it is possible and often convenient to change to the parent of the current directory by using the following:. Another convenient feature of cd is the ability for any user to return directly to its home directory by merely using a tilde as the argument.
A home directory, also called a login directoryis the directory on a Unix-like operating system that serves as the repository for a user's personal filesdirectories and programs. It is also the directory that a user is first in after logging into the system. A tilde is a short, wavy, horizontal line character that represents the home directory of the current user.
That is, any user can return immediately to its home directory by typing the following and then pressing the Enter key:. And it is just one of the numerous shortcuts that help make the command line on Unix-like operating systems so easy to use. When followed by a space zero cd linux then a hyphen, cd both returns the user to the previous current directory and reports on a new line the absolute pathname of that directory.
This can further enhance the already convenient toggling capability of cd. The -P option instructs cd to use the physical directory structure instead of following symbolic links.
The -L option forces symbolic links to zero cd linux followed. Created May 25, Updated August 11, The Linux Information Project.

When you want to completely erase data from a hard drive, zero fill is one of the most thorough methods. The easiest way to ensure that that data is not recoverable is to write data over it. This is where the zero fill comes in handy. Every time zero cd linux run the zero fill process on a hard drive, it writes zeros over your existing data. The more times you run the zero fill process, the harder it will be to recover anything.
This process is highly recommended if you are planning on selling a device with a hard drive or flash memory, or if you buy or receive a used computer from someone. You are protecting yourself, and in some cases the person you received the device from, by thoroughly wiping the existing data.
Many hard drive companies provide utilities that can perform a zero fill on your drive. If you zero cd linux find a zero fill utility for your drive, you can use a Linux Live CD to do it for free.
Linux Live CDs allow you to try out union jack papillon remixes linux distributions without installing the operating system on your hard drive.
When you insert the CD and boot from it, a working version of the operating system loads into the PCs memory, and you can use most of the available functions to get an idea of how zero cd linux works without committing time and energy to an installation. Both Knoppix and Ubuntu have this functionality. We used Ubuntu for this example. Load the Ubuntu web siteand then click on Download Ubuntu. Select your Download location from the drop-down menu, and click Begin Download.
Zero cd linux Ubuntu boots, you will be prompted to choose a language from the menu. Choose English or whatever language you are most comfortable with. The main Ubuntu menu will load. Choose Try Ubuntu without any change to your computer.
Newer versions of Ubuntu will look different and have different options, but there should always be some option to run Ubuntu from the media directly. Click on ApplicationsAccessoriesand then Terminal. Choose the hard drive you would like to zero fill. Type sudo fdisk -l and a list of all of the drives and partitions on the system will be displayed. Use the shred command to zero fill the partition of zero cd linux choice. Hit Enter to begin the process.

Knoppix is one of the oldest Linux distributions still around, and it was one of the first Linux Live CD distributions. If my memory is correct, the first generally available release of Knoppix on a Live CD was made sometime in late I don't think it is exaggerating to say that Knoppix set the standard for Live Linux distributions when it was released, or that the Linux world as a whole learned a lot about how Live distributions should be done, and how powerful, versatile and useful they could be.
Fedora Hands on with five different desktops. Read More. Over the years, Knoppix has evolved and expanded. In about a Live DVD version was added, with loads of additional applications, utilities and packages included.
My first use of Knoppix came at SANS training classes, where they were using the Live CD version as a convenient way for course participants to gain access to Linux tools. Those classes require attendees to bring their own prit 842041, and until a few years ago the majority of them would be running Windows.
So, to get to the point rather than zero cd linux about the history of it all: There is also one clear example of the "experience shows" that I mentioned above; for computers which cannot boot from USB drives such as the Lifebook S I am currently typing this onthere is also a "bootonly" CD version. I found the file list on the download site to be a bit confusing, so let me see if I can paraphrase it simply:. I have tried with dd no joyzero cd linux I haven't tried using unetbootin yet. When you boot the Live image, the real fun starts.
I have to admit that I just about jumped out of my chair when the woman's voice suddenly and completely unexpectedly announced "Initiating startup sequence"! This release of Knoppix is running Linux kernel 3. Oh, and it includes Compiz Fusion, with lots of desktop effects enabled! Olidia font found this to be a particularly amusing experience, using what is generally thought of zero cd linux a "lightweight desktop", but with wobbly windows, animations when windows open or close, a desktop selection cube and heaven knows what zero cd linux.
This system was installed from the DVD distribution, and as I said above, that is really the "all in" version. It is absolutely chock full of applications, utilities, packages and even alternative desktops. I will only give a few examples from each menu:. Honestly, I just picked those at random. There are a few useful things to know about this. First, the Knoppix installer called 0wn, for Zero Work Neededis not at all like any other installer you might have used for another Linux distribution.
It doesn't worry about niceties such as setting up timezones, keyboard maps and user accounts, and it doesn't have any flexibility at all when it comes to disk partitions and filesystems. If you already have the necessary partition, 0wn will find it and offer to use it for the installation.
If you don't have a suitable partition 0wn will let you run gparted so that you can create one, or it will offer to automatically partition the disk for you - it would take a brave person, or a totally empty hard drive, to accept that last offer, in my opinion. The DVD image is a 3. Keep these sizes in mind when you are setting up the partitions for Knoppix. It is exactly what the name implies, it puts up the window shown here, listing the available desktops, you can select the one you want and then OK, and it will configure that zero cd linux then restart the X server, all without rebooting or even logging out.
You need to be a bit careful about this, because restarting the X server will terminate all running programs which have graphical output.
Keep that in mind, or you will get a rather unpleasant surprise when you try it. That is a very typical looking KDE desktop. Again, that is a pretty typical Gnome 3 desktop, with the application menus structure and content the same as for the LXDE and KDE desktops seen above. Knoppix is not only interesting as a Live distribution, though: The Knoppix installer 0wn is a zero cd linux, uh, different.
Many people zero cd linux the Fedora installer ' anaconda ' to be the height of complexity; I don't necessarily agree with that, but if I were to look at it that way I would consider the Knoppix installer to be zero cd linux opposite extreme, the height of minimalism. If you are seriously interested in Linux, and you have never tried Knoppix, you owe it to yourself to download one of the Live images and at least give that a try.
