====== The bash terminal in MacOS X ======

Many tasks in the following weeks will need to be performed on the terminal (or 'command line').

Hit ''CMD'' + ''SPACE'' to open the search window, enter 'terminal' and hit ''RETURN''.
<note tip>In order to keep the terminal in the dock also after you close it, right click on the symbol and select 'Options' -> 'keep in dock'.
</note>

Let's continue with a list of useful commands -- just type them into the command line and confirm with ''RETURN''.
<code bash>
ls             # get list of files in the current directory
mkdir molsim   # make directory 'molsim'
cd molsim      # change into directory 'molsim'
cd ..          # go up one directory
pwd            # print path to the current working directory
open .         # opens current directory in Finder
</code>

Now it is time to copy some files from the teacher account.

<code bash>
cd                                    # change into your home directory
cp ~c329s00/exercises/.bash_profile . # copy course-specific system settings
cd molsim                             # change into directory 'molsim'
cp -r ~c329s00/exercises/intro .      # copy directory 'intro' from teacher account
</code>

After this, please close and reopen your terminal in order to activate the course-specific 
settings you copied.

We are now ready to get started. Below you find some additional commands that will come in handy later.

<code bash>
open myfile     # opens 'myfile' with default program
open -t myfile  # opens 'myfile' in text editor
vim myfile      # opens 'myfile' in vim (powerful command line text editor)
</code>

In order to take a screen shot, hit ''CMD''+ ''SHIFT'' + ''4''.
