Recently I discovered a web page that provide command line interface for google search, as the author called it as Google Shell. Check out the screenshot, and also try it out at http://goosh.org/.
It does looks like unix-shell, thank to Ajax. You may think that is hilarious, but don’t make judgment before trying it out. For me, that is usable. and I should say that is perfect for CLI hardcore users.
I like google translate command line feature very much. Try this:
firstname.lastname@example.org:/web> translate en de hello translating "hello" from "english" to "german": "hallo"
Surprisingly, when you hit tab, it does support auto complete and hitting arrow key up and down support keeping history list.
By the way, I find the idea of ordering pizza through command line is even crazy. Imagine you can write a script to loop your pizza choices and put the script to run as cron job ordering pizza as your breakfast every morning.
