The interface looks quite similar to a Unix Shell and can be easily adapted by anyone who is bored using the normal web browser way of searching.
To use Goosh you will have to type commands like you type in UNIX to get the search results, and example of a command to find Techie Buzzin Google search is;
web Techie Buzz
You can also search Wikipedia using Goosh, the command for searching Wikepedia is;
wiki Bill Gates
There are also other commands using which you can search Google Unix style, to see all the commands simply type hor helpwithout the quotes and press Enter, you should see a list of commands you can use along with the parameters you need to pass to it.
Overall Goosh provides a decent experience for heavy UNIX users and I can say that transitioning from Putty to Goosh will be a piece of cake and over time I may definitely ditch the regular Google Search :).
Give Goosh a try and let me know your feedback on what you think about it.
