Section 0 - Summary

Summary

In this section we learnt:

  • That this book is for IT professionals, hobbyists or anyone who wants to learn more about how to work with computers
  • What the shell is, and why we might want to use it
  • How to open the shell programs for Windows, Mac and Linux which are installed by default
  • How to configure the shells for Windows or Mac to behave in a Linux-like way to allow us to follow on with the rest of the book

We introduced the following commands:

  • cd - which changes directory
  • pwd - which prints the current working directory
  • ls - which lists the contents of a directory
  • echo - which writes text to the screen
  • open - which will open a file or folder

We also briefly introduced variables, which are special values which start with the dollar symbol, such as $HOME which stores the user's home directory. We saw that each directory contains two special directories - .. which represents the parent directory, and . which represents the current directory.

With these tasks complete we can now move onto the next section.
