We cannot imagine a programming language without the concept of arrays. It doesn’t matter how they are implemented among various languages. Instead arrays help us in consolidating data, similar or different, under one symbolic name.
Here as we are concerned about shell scripting, this article will help you in playing around with some shell scripts which make use of this concept of arrays.

When the Raspberry Pi team launched a tiny, low power computer priced at just $35, it was pretty remarkable. But that was 2 years ago, and while the Raspberry Pi has seen a few updates in that time, it’s still powered by the same single-core 700 MHz Broadcomm BCM2835 ARM11 processor.
Over the past few years a number of other single-board computers with more powerful hardware have appeared, but they usually also have higher price tags.
Hardkernel’s ODROID-C1 doesn’t though… it’s a quad-core mini computer that sells for just $35.

If you are running a satellite backend system such as TVHeadEnd or MediaPortal (or MythTV, if you are one of the lucky few that can actually get it to work), and you use Kodi or the MythTV frontend, then it is possible to populate the schedule grid with listings from many sources. Note I did not say that it is easy, just that it is possible. The key is to use an external program … These are commonly referred to as “schedule grabbers”, or just “grabber” programs.
The real trick is figuring out how to use one of those programs. …..

I’m a new Linux / Unix system user. How can I set encrypted tunnel between my desktop/laptop computer and server in a remote data center to bypass the limits in a network? How do I create a reverse SSH tunnel on Unix-like systems?
SSH tunnelling can be thought as a poor-man’s-VPN. It is handy in situations where you would like to hide your traffic from any body who might be listening on the wire or eavesdropping. You can use such tunnel between your computer and your Unix/BSD/Linux server to bypass limits placed by a network or to bypass NAT, and more.
