How To Look Like A UNIX Guru

Post date: October 30, 2006, 02:10 Category: Miscellaneous Views: 5716 Comments
Tutorial quote: UNIX is an extremely popular platform for deploying server software partly because of its security and stability, but also because it has a rich set of command line and scripting tools. Programmers use these tools for manipulating the file system, processing log files, and generally automating as much as possible.

If you want to be a serious server developer, you will need to have a certain facility with a number of UNIX tools; about 15. You will start to see similarities among them, particularly regular expressions, and soon you will feel very comfortable. Combining the simple commands, you can build very powerful tools very quickly--much faster than you could build the equivalent functionality in C or Java, for example.

This lecture takes you through the basic commands and then shows you how to combine them in simple patterns or idioms to provide sophisticated functionality like histogramming. This lecture assumes you know what a shell is and that you have some basic familiarity with UNIX.

Managing Filesystems : fstab

Post date: April 15, 2005, 23:04 Category: System Views: 6645 Comments
Tutorial quote: Understanding how the BSD filesystem manages disk space is critical to successfully managing a BSD server or workstation. However, this topic is generally overlooked since it is rarely used outside of installation and upgrades. It is also a very simple topic and most people assume you understand how it all works.

This article gives a quick synopsis on filesystem layout and tries to briefly explain how to understand /etc/fstab. The fstab(5) man pages, while good, do little to teach the basics to new sysadmins.

TrueCrypt Tutorial: Truly Portable Data Encryption

Post date: July 2, 2007, 23:07 Category: Security Views: 3556 Comments
Tutorial quote: TrueCrypt is a free software that encrypts data on-the-fly. Right now the newest version released is version 4.3. You can create an encrypted hard drive, a separate partition or a directory with TrueCrypt. It does not simply encrypt the content of files, but their names and the names of the directories they are in as well. Moreover there is no way to check the size of the encrypted directory/HDD/partition. TrueCrypt is available for Windows and Linux.

Editing Images With Pinta

Post date: October 11, 2011, 07:10 Category: Desktop Views: 4210 Comments
Tutorial quote: This article is about how to use the Pinta graphical editor to edit pictures and covers some of its most important features. Pinta is a lightweight image editor for Linux and is far more easier to handle than Gimp but still has a large variety of tools and features to use. It can be used for quick editing like resizing images or adjusting the colours of photographs, but also for more professional tasks which depend on layered images and more. It is a good mixture between MS Paint and professional image editing tools and is recommendable for most purposes of image-editing-everyday-use.

rsnapshot - Local/Remote Filesystem backups utility in openSUSE

Post date: October 6, 2008, 21:10 Category: System Views: 3869 Comments
Tutorial quote: rsnapshot is a filesystem backup utility based on rsync. Using rsnapshot, it is possible to take snapshots of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of multiple full backups, while only taking up the space of one full backup plus differences. When coupled with ssh, it is possible to take snapshots of remote filesystems as well.

Benchmarking Maildir Delivery on Linux Filesystems

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3048 Comments
Tutorial quote: The goal of this set of benchmarks is to determine which of the leading Linux filesystems (ext2, ext3, ReiserFS, and XFS) offer the best performance when used for accepting maildir deliveries. The resulting system should be a good balance of delivery and retrieval performance under potentially high concurrent filesystem load.
