Debian 6.0 is a free operating system, coming for the first time in two flavours. Alongside Debian GNU/Linux, Debian GNU/kFreeBSD is introduced with this version as a technology preview.

The Origins of Linux

[Recorded Sept 19, 2001] Linus Torvalds, the creator of the operating system phenomenon Linux, tells the story of how he went from writing code as a graduate student.




Use fdisk to Create a Swap Partition

This section assumes a swap partition is available, appropriately sized for the RAM on the local system. This section illustrates how to create an additional swap partition using fdisk. You already know how to open a disk for editing with fdisk. Here, I create a swap partition on my second SCSI hard drive. For the purpose of this exercise, I assume there’s at least 512MB of free space available. (For learning purposes, the swap partition can be smaller.)




Copying Files and Directories

Use cp ("copy") to copy files. It takes two arguments: the source file, which is the existing file to copy, and the target file, which is the file name for the new copy. cp then makes an identical copy of the source file, giving it the specified target name. If a file with the target name already exists, cp overwrites it. It does not alter the source file.




Creating a File Archive

To create an archive with tar, use the `−c' ("create") option, and specify the name of the archive file to create with the `−f' option. It's common practice to use a name with a `.tar' extension, such as `my−backup.tar'.




Checking In a File Revision

When you have a version of a file that you want to keep track of, use ci to check in that file with RCS. Type ci followed by the name of a file to deposit that file into the RCS repository. If the file has never before been checked in, ci prompts for a description to use for that file; each subsequent time the file is checked in, ci prompts for text to include in the file's revision log. Log messages may contain more than one line of text; type a period (`.') on a line by itself to end the entry.




Show who is logged in and what is he doing.

The w tool is similar to who, but it displays more detail. It outputs a header line that contains information about the current system status, including the current time, the amount of time the system has been up and running, and the number of users on the system.




Redirecting Error Messages to a File

To redirect the standard error stream to a file, use the `>' operator preceded by a `2'. Follow a command with 2> and the name of the file the error stream should be written to.




What is SWAP?

Swap is an extension of the physical memory of the computer. Most likely, you created a swap partition during Linux installation. You can verify the amount of swap space available on your system using:
