Linux “symlinks” is a handy utility for managing symbolic links. It can clean up the sort of problems that come from carelesness when creating symbolic links.

Most zip or tar archives are made so that they unpack into a sub-directory. However, every now and then you run into one that wasn’t done that way, and if you happen to unpack it in a directory that already has files, you end up with confusion: what was just unpacked and what was already here?
Ah, finally: no more of for i in 1 2 3 4 5 6 7 8 9 0 do
.. whatever done
Most shells have some provision for aliases. Aliases can assign default behavior to a command (for example “rm” is often aliased to “rm -i”) or can be used to create new commands (a typical example is “ll” aliased to be “ls -l”).
In the beginning, when large creatures lumbered through damp tropical forests and furry mammals hid quivering in their burrows, “ps” had no built in abilty to change its sort order. You got what it gave, and if you wanted it otherwise, you ran it through “sort” yourself. That is the Unix Way: small tools, working together with pipelines.
Linux® From Scratch (LFS) and its descendants represent a new way to teach users how the Linux operating systems work. LFS is based on the assumption that compiling a complete operating system piece by piece not only teaches how the operating system works but also allows an independent operator to build systems for speed, footprint, or security.
It’s obvious — Linux has become an attractive option for non-x86 platforms. Why? In this article, the author examines the reasons for this, including the fact that Linux on non-x86 enables affordable, easy-to-do virtualization; provides for better reliability, power consumption, and extended memory support; covers the lower and upper ranges of machines, giving users options outside of the middle range; revitalizes older hardware; and drives innovation.
The wave of migration to open source in business has the potential to cause a tremendous porting traffic jam as developers move the pervasive Windows® applications to the Linux platform™. In this three-part series, get a mapping guide, complete with examples, to ease your transition from Windows to Linux. Part 1 introduces processes and threads.
Learn how to set up a PPG on your own, configure the settings to your own taste, develop push content, and test it with a mobile handset simulator over a TCP/IP network on a LAN.
Inotify is a file system event-monitoring mechanism slated for inclusion in upcoming Linux™ kernels that is designed to serve as an effective replacement for dnotify, which was the de facto file-monitoring mechanism supported in older kernels. Inotify is a powerful, fine-grained, asynchronous mechanism ideally suited for a variety of file-monitoring needs including, but not limited to, security and performance. Learn how to install inotify and how to build a sample user-space application to respond to file system events.
