cream bash ide – vim with bash support

Here you can find the cream editor. This is basically vim editor with lots of customizations thus making it simpler for the users to use the editor directly.

This version already has the bash and perl support plugins and thus you can start using them as IDE without the need to add any plugins. It has a simple and advanced mode. In the simple mode you need not worry about all the modes of the vi/vim editor. How cool is that 🙂

glances – Get a glimpse of the whole system

You would have used top at some point of time. Did you not wish that instead of just the processes it list all the vital statistics of the system as a whole.

g flag in :s useless in vim

If you are using snipmate, then make sure that you read the description of the plugin to add the required lines to the vimrc file to get the full functionality. You would love to type henceforth in your favourite editor. We will talk about more on Intellisense in few days time.. Chao till then.
