 In general, it is good to spend as little time as possible in the insert mode and extensively use the command mode to achieve various tasks.
 To save the file, use ``:w`` in the command mode. From here on, it is understood that we are in the command mode, whenever we are issuing any command to vim.
 To save a file and continue editing, use ``:w FILENAME``
-The file name is optional. If you donot specify a filename, it is saved in the same file that you opened. If a file name different from the one you opened is specified, the text is saved with the new name, but you continue editing the file that you opened. The next time you save it without specifying a name, it gets saved with the name of the file that you initially opened.

 To save and quit, use ``:wq``

 .bashrc
 -------
-What would you do, if you want bash to execute a particular command each time you start it up? For instance, say you want the current directory to be your Desktop instead of your home folder, each time bash starts up. How would you achieve this? Bash reads and executes commands in a whole bunch of files called startup files, when it starts up.
+What would you do, if you want bash to execute a particular command each time you start it up? For instance, say you want the current directory to be your Desktop instead of your home folder, each time bash starts up. How would you achieve this? Bash reads and executes commands in a whole bunch of files called start-up files, when it starts up.
 When bash starts up as an interactive login shell, it reads the files ``/etc/profile``, ``~/.bash_profile``, ``~/.bash_login``, and ``~/.profile`` in that order.
-When it is a shell that is not a login shell, ``~/.bashrc`` is read and the commands in it are executed. This can be prevented using the ``--norc`` option. To force bash to use another file, instead of the ``~/.bashrc`` file on startup, the ``--rcfile`` option may be used.

 Now, you know what you should do, to change the current directory to you Desktop. Just put a ``cd ~/Desktop`` into your ``~/.bashrc`` and you are set!
-This example is quite a simple and lame one. The startup files are used for a lot more complex things than this. You could set (or unset) aliases and a whole bunch of environment variables in the ``.bashrc``. We shall look at them, in the next section where we look at environment variables and ``set`` command.

 .vimrc
 ------
-``.vimrc`` is a file similar to ``.bashrc`` for vim. It is a startup file that vim reads and executes, each time it starts up. The options that you would like to be set every time you use vim, are placed in the ``.vimrc`` file, so that they are automatically set each time vim starts. The recommended place for having your ``.vimrc`` is also your home directory.

 The file ``/etc/vimrc`` is the global config file and shouldn't usually be edited. You can instead edit the ``~/.vimrc`` file that is present in your home folder.
 There are a whole bunch of variables that you could set in the ``.vimrc`` file. You can look at all the options available, using the ``:set all`` command in vim. You could use the ``:help option_name`` to get more information about the option that you want to set. Once you are comfortable with what you want to set a particular variable to, you could add it to ``.vimrc``. You should also look at ``:help vimrc`` for more info on the ``.vimrc`` file. If you already have a ``.vimrc`` file, you can edit it from within vim, using ``:e $MYVIMRC`` command. We shall look at some of the most commonly used options.
