In the past I’ve posted an article regarding the basic usage of grep, one of the commands that I use daily at work to search a text within multiple files, or a text string in the list of running process of a Linux server, but I’ve forgot to show you a small and useful option : How to colour the output that you get from grep to highlight the text you were searching for in a long line.

This is a small option of this powerful command but can save your eyes when searching for a particular property of a Java process that is 4 or 5 lines long.

Jobs that are particularly long running that run on a different computer or several different computers even, such as in a grid environment, are good candidates for multitasking. Defragmenting your disk drive or running a search for a particular query string on your local hard drive are examples of long running local jobs that can be multitasked while running other tasks. Jobs such as long database queries or batch loads onto a remote server are examples of jobs that are controlled in a single session, but can be multitasked in a Linux environment so several of these sessions can be run at the same time.

Techies and gamers seem to always be faced an unfortunate lack of video games available for the Linux operating system. While many techie gamers would prefer to move to a cleaner, leaner Linux environment, the Microsoft world it seems has held the monopoly when it comes to supporting great computer games. While Apple has made great strides toward supporting a wider variety of games, Linux clearly trails behind the big commercial operating systems in game support.

To help alleviate this unfortunate situation Linux aficionados find themselves in, here is a list of the top ten Linux games released or updated in 2012
