What's the best partition scheme for dual booting Windows XP and Gentoo Linux?

Some people do not like having a separate /home partition for Linux, though it is better for recovery purposes. For the purposes of the question, it is assumed that you do not want a separate partition for your /home directory.

The best performance is provided by placing a Linux swap partition first on the drive. This should be at least double the amount of RAM you have installed, but no larger than 1 GB. You will have to move the XP partition to the end of the drive after you have installed it.

The partition after the swap partition should be a Linux partition. I personally prefer ReiserFS, but ext3 is slightly more popular, mostly due to the larger number of error recovery tools.

The last partition should be the Windows XP partition.

What does CD means in Linux os?

If by "CD" you mean the linux terminal command "cd", it stands for "change directory". It allows you to move from one directory to another. It's basically the same as Window's cd command.

cd / will take you to the very first directory, which is the root directory. (Do not confuse this with /root directory)

cd .. will take you one directory up

cd ~ will take you to your (currently logged in user's) home directory, which is, (/home/)

cd - will take you back to where you were before you change directories.

Do you have to compile Linux software before using it?

You can if you really want to! But, most Linux software is already compiled and ready to be downloaded and installed. Note that Linux is the kernel from which many distributions (distos) branch out - Ubuntu, Linux Mint are but two examples.

How can you read a .dat file in Linux?

There's actually no such thing as a ".dat" file. The .dat extension is a generic one used for "data." It does not have any specific format and thus there is no tool that can open all, or even a majority, of these files.

What is diffrance between Linux and unix?

Shell is a program which allows the user to access the computer system. Shell is an interface between the user and computer system.

Kernel is the only way through which the programs (all programs including shell) can access the hardware. Its a layer between the appliation programs and hardware. It is the core of most of the operating systems and manages everything including the communication between the hardware and software.

KERNEL is the core part of operating system. It contain modules like device modules and other modules etc. Kernel is written in C language. Basically kernel is mediator between hardware and Operating System. But SHELL is an interface between users and operating system. Both are mediator but work is totally different.

Let we have an example of "eject" command in Linux operating system:

User give a command to Shell through input device like keyboard and see that command on video Device like monitor, but in actual concept is user give a command to shell, then this shell transfer that command to kernel.when kernel have module of that command then it transfer to hardware like CDROM. After that hardware behave as the module in kernel and then kernel again transfer the output to Shell. And finally shell transfer that output to user.

Hardware <---> Kernel <---> Shell <---> User

Which Linux commands can be used to create backups of filesystems and directories?

best option is to use dd command as belloaw :

dd if=INPUT-FILE-NAME of=OUTPUT-FILE-NAME

So to backup /dev/hda3 under Linux command should be as follows :

# dd if=/dev/hda3 of=/backup/myhostname-15-nov-05-hda3.bak.dd

Backing up entire disk/partition with dd commandBackup /dev/hda to /dev/hdb:

# dd if=/dev/hda of=/dev/hdb conv=noerror,sync

How do you install OpenSUSE?

Be sure to read the online instructions first! It is important that you understand what would delete the Windows OS, when to partition manually.

You may buy the CD or download the ISO file. If possible, try a "live" version to play with; installation is optional. There are also versions of Linux that can be installed as a Windows program, then removed just as easily.

You need to burn the ISO image to a CD. If you are using Windows, try a freeware program called "ImgBurn." Find the burn speed option and select x4 or slower! This may make the CD more durable and readable. You cannot just drag and drop it; this would leave a copy of the ISO file on the CD instead of writing (burning) the decompressed image (filesystem).

After you do this, just reboot your computer with the disc in the drive. Most computer will boot directly to the CD. If it continues into Windows, you'll need to enter your BIOS and change the boot order, CD first.

How do you determine leap years using Linux?

If you want to determine whether a year is a leap year. Use the cal command for the month of February. So to check 2012, for example, do:

cal 2 2012

and see if it prints 28 or 29 days.
