This blog is going to cover the ins and outs of using Linux® from the
command line.

So before we talk about Linux®, we have to first ask…

…what is Linux®?

Linux® is an operating system. An operating system is the thing that
makes a computer workable. Without it, the computer would be unable to
do anything. No internet access, no games, no nothing. The operating
system is the framework that allows the computer to actually do things.
Without one, you’ve really got an expensive machine that can turn on the
fan and make beeps, but do nothing else.

Unix is an operating system that was created back in the mid 1960s to
run on a new type of computer. It has a long and convoluted
history, but it boils down to ‘new computer system fast and spiffy’.
It was so spiffy various people made it so that it could run on other
types of machines.

And that’s where Linux® comes in. Linus Torvalds wrote a version that
would run on the personal computer systems that we know and love today.
It is free to download and install and has been made available to a
number of hardware specifications. This means it can run on laptops,
netbooks, desktops, smartphones, PDAs, and more. Basically if it has a chip
in it, someone tried (and probably succeeded) to make Linux® run on it.

So this blog is going to talk about Linux® and also how to use various commands and make things work.  And do spiffy things, while we’re at it.
