Terminal introduction workshop

Terminal is the Mac OS X command line app for controlling the system via a text based interface, instead of the traditional graphical interface.

Put a list of commands here.

How Terminal works

File:Terminal2.png

The standard streams for input, output, and error.

In it's most simple terms, the Terminal operates on a series of Inputs and Outputs. You input one command into the terminal, and it'll pass the data through the programmed function before outputting you the result.

By stringing (aka. piping) commands together, you can take the results of an Output and manipulate it further before presenting the completed Output to the user.

For example, a user could use banner to create an ASCII glyph, save it to a file and then lp (local print) to print a file. By stringing them together however, the user can take the direct result from the banner command and then send that directly on to the printer, without having to deal with the intermediate file manipulation.

Using the Terminal has many advantages over the typical desktop GUI (Graphical User Interface) you're likely accustomed to. Using command line can allow you to write scripts to automate tasks, combine and string simple commands together and manipulate file contents, all from within the Terminal.
