In some instances you may find that the default configuration of VIM has the backspace key disabled. Like many others I expect to be able to delete characters right-to-left like most other text editors. Unless you are doing some very minor editing, it quickly becomes a hassle to use the delete key.

Luckily there is a quick fix. Add the following line to the .vimrc configuration file in your home directory:

set backspace=indent,eol,start

You can change for all users by placing this previous line in the /etc/vimrc configuration file.

Many distributions have syntax highlighting in vim enabled with their default installation. In Ubuntu as well as other Debian based distributions, this is not the case. By default Ubuntu installs the vim-tiny package which does not support syntax highlighting or many other advanced features.

You can see by following the chain of symlinks that in the default installation vim calls vim.tiny.

$ which vim

/usr/bin/vim

/usr/bin/vim -> /etc/alternatives/vim -> /usr/bin/vim.tiny

If you want additional features including syntax highlighting you need to install the vim package.

$ sudo apt-get install vim

Now vim uses vim.basic which is what we want. This version supports all the advanced features.
/usr/bin/vim -> /etc/alternatives/vim -> /usr/bin/vim.basic

The last step is to actually enable syntax highlighting.

To enable it for a single session go into command mode and enter this command:

:syn on

Make these changes permanent for every vim session by opening or creating the .vimrc configuration file in your home directory.
/home/username/.vimrc

Insert the following lines.

if has ("syntax")
        syntax on
endif
