1. Installing RAR

To be able to compress/decompress rar files under Ubuntu/Linux Mint, you need to install RAR packages with this command:

sudo apt-get install unrar rar

2. RAR Uses

- To extract the contents of a .rar file, run this command:

unrar e file.rar

or

rar e file.rar

- To extract an archive file and keep full path intact, run this command:

 rar x folder.rar

- To compress a file into a rar file, run this command:

 rar a file.rar file.ext

Replace ext with your file format you want to compress (txt, exe, avi, ogg, etc.)

- To compress a folder, run this command:

rar a -r folder.rar path/to/folder/

- To compress and split the file into fragments, run this command:

rar a -v20000 file.rar file.mp4

or

rar a -v20000 -vn file.rar file.mp4

The commands above will compress file.mp4 and split it into many files, each one has a size of about 20MB.

Nvidia wakes up Performance Doubled for Games on Linux!

Linus Torvalds as we all know by now is the one who started our adventure by Linux old-timers, nothing less than the ‘ inventor of the Linux kernel. The evolution of the system operation has progressed hand by hand, but there is a manufacturer that Torvalds just does not go down: we’re talking about nVidia, one of leading manufacturers of GPU (you remember the umbrella gesture that Torvalds, in no uncertain terms, he turned the company?)
Well, perhaps it was just that, perhaps it was the ‘ advent of Steam on Linux might have been about countless loss precisely because the lack of support for the operating system of penguins but we arrived … time to nVidia have a breakthrough, but this time, it seriously. According to a post appeared on the official website of nVidia the performances of the video driver R310 (current version 310.14) would be significantly increased compared to the last series, the 304, there is even talk of a doubling of the speed of running and a drastic reduction in load times for games . Everything tested using Steam for Linux. Here’s what we read on the official website of nVidia:


Into NVIDIA today-announced the latest NVIDIA ® GeForce ® drivers – R310 – double the performance (1) and dramatically reduce game loading times for Those gaming on the Linux operating system.
