Using grep command

Let's talk about something used by some users of Linux that handle large amounts of information, the grep command.
This command lets you search for occurrences of text or expressions in a file or stdin, excellent links to search, numbers, IPs and other elements in large log files.

Tips to help you choose your Linux distribution

In the last three days I have been programming in android since I get up until I go to bed, so the last thing I want to see now is Java. For that reason I'll talk about another topic: Linux distributions.

As it happened to me, anyone who wants to move from Windows to Linux will face her first difficulty, choosing between a big number of distributions.

But what is a distribution?

Just like in windows family, you have Windows 9x, NT and CE, and for each of them, you have versions (as: 95,98,ME). In Linux it isn’t so different, with the particularity that the core (kernel) are the same.

So what’s the difference?

In Windows you have a company with total control over the core, applications and interface that the operating system will have, the final user may change something, but not as much as he may want.

In Linux anyone could grab the kernel, append a bunch of applications, tweak some parameters and puff, there’s a new distribution!

The freedom offered by Linux can look very good, but it isn’t always. This leads beginners to get confused and to have a fragmentation of the “help content”. Even worse is the fact that normally for the same thing there are at least two alternatives, both with their flaws and both have their qualities.

So I'll give some tips to help you choose one, and facilitate your entry into the magic of Linux
