====== The bash terminal======

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

<note tip>
If you use Mac OS X:
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 start 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 (Mac OS X)
</code>

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

<code bash>
cd                                    # change into your home directory
cp ~student10/.bashrc .               # copy course-specific system settings
cd intro                              # change into directory 'intro'
</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>
nano myfile     # opens 'myfile' in nano (an 'easy' command line text editor)
vim myfile      # opens 'myfile' in vim (less intuitive but more powerful command line text editor)
</code>

(on Mac OS X): In order to take a screen shot, hit ''CMD''+ ''SHIFT'' + ''4''.
