One the best ways for beginners to get familiar with Gnu/Linux is to start by learning about LPIC (It has BASH programming in itself, too).

And if you forget any command or if you want take a look at arguments or you want to learn about a new command, you can read manual pages using man COMMAND in terminal. (For example man grep)

In this example:

1) kill -9 terminates a process.

2) ps shows current processes

3) grep print lines that match special patterns

4) awk '{print $2}' shows second column

And | (pipe) gives the output of the previous command, as an input to the next command.
