makeself.sh is a small shell script that generates a self-extractable tar.gz archive from a directory. The resulting file appears as a shell script (many of those have a .run suffix), and can be launched as is. The archive will then uncompress itself to a temporary directory and an optional arbitrary command will be executed (for example an installation script). This is pretty similar to archives generated with WinZip Self-Extractor in the Windows world. Makeself archives also include checksums for integrity self-validation (CRC and/or MD5 checksums).

Man pages are written by sys-admin and developers for IT techs, and are intended more as a reference than as a how to. Man pages are very useful for people who are already familiar with Linux, Unix, and BSD operating systems. Use man pages when you just need to know the syntax for particular commands or configuration file, but they are not helpful for new Linux users. Man pages are not good for learning something new for the first time. Here are thirty best documentation sites on the web for learning Linux and Unix like operating systems.

PDNSD is a non authoritative caching DNS server. It maintains a disk cache of the queries that your system performs and subsequent queries will be faster from the cache. It is safe enough to be used on a personal Unix/Linux system as a home Desktop or a Laptop.

tcpdump is one of the original packet capture (or "sniffing") tools that provide these analysis capabilities, and even though it now shares the field with many other utilities, it remains one of the most powerful and flexible.

If you think that tcpdump has been made obsolete by GUI tools like Wireshark, think again. Wireshark is a great application; it's just not the right tool for the job in every situation. As a refined, universal, lightweight command-line utility—much like cat, less and hexdump—tcpdump satisfies a different type of need.

By compiling Gnome Shell using the instructions in this post, all the packages the Gnome Shell script will download and compile will not replace any existing libraries and it will install in your home folder, so you don't have to worry about breaking stuff on your system (excluding here the build dependencies of course, which are usual packages from the Ubuntu repositories and will install just like any other package).

This tool lets you simulate keyboard input and mouse activity, move and resize windows, etc. It does this using X11's XTEST extension and other Xlib functions.
Additionally, you can search for windows and move, resize, hide, and modify window properties like the title. If your window manager supports it, you can use xdotool to switch desktops, move windows between desktops, and change the number of desktops.

"BAR is backup archiver program. I developed this program after I could not find a simple to use archiver program to create compressed and encrypted archives of my files which can be stored on a cd or dvd. While I devoped the program - development is still not finished - I added some more useful features. Now I use the program to make automated backups from all my files either on dvd or directly via an Internet connection to a file server. "

"This tutorial explains the installation of a Samba fileserver on Ubuntu 10.04 and how to configure it to share files over the SMB protocol as well as how to add users. Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has his own home directory accessible via the SMB protocol and all users have a shared directory with read-/write access. "

"Novo Builder is a Debian GNU/Linux tool for creating your own up to date Ubuntu variants (only Ubuntu variant for the time being) customised to include the programs, themes and customised settings that you want. You don’t have to learn all the codes or any of the technical process. With a few mouse clicks and a long waiting time, you can quickly create your very own OS (and probably boost it to your friend)."

"Swatch isn't a cleverly designed watch from the 1980s but you'll think it's just as handy (and cleverly designed) as one. Like Logwatch, swatch is a perl script that watches your logs but swatch watches them for regular expressions that you configure. Swatch will notify you via mail or the console screen (stdout) when it matches the configured log file entries with your watchfor directives."

"Standalone Network Attached Storage (NAS) servers provide file level storage to heterogeneous clients, enabling shared storage. This article presents the basics of NAS units (NFS servers) and how you can create one from an existing system. "

"In a recent walkthru we outlined the steps for taking an existing server and converting it into a NAS box. That article assumed that you already installed Linux on the server and you will maintain that installation (i.e. updates, security, etc.). This article takes examines an alternative: a dedicated NAS distribution called OpenFiler that allows you to very simply create a stand-alone NAS box that can be administered over the web. "
