[Intro Music]
In the previous few lectures, we
have talked about commands and
I have explained to you what is
difference between options and
arguments. And of course, you could
use multiple options and multiple
arguments in every single command.
In order to find out which options
are supported by a specific
command, you need to enter either
'man', and command; or command, and
'--help' option. In such case, you
will see a list of all available
options you're able to use. Also,
you could find out which arguments
are mandatory and which are
optional. All right, now let's
proceed, and let me now talk about
processes. And you'll understand
that basically, when you enter each
command, you start specific
process. And there are different
processes. There are processes that
simply quickly start, and afterwards
they're stopped. For example, when
you enter 'ls' or 'mkdir' command,
you start corresponding 'ls' or 'mkdir'
process, and those processes do
their job and afterwards, they
simply stop. Also, there are so
called long running processes like
'bash' shell process or 'sh' shell
process and so on. I'll talk about
all of that in this and next lectures.
Let's get started.
