Zsh
Zsh is a very interesting shell that hase lots of interesting features. In fact it could seen as an extended bash shell, at least according to wikipedia.
This is the homepage. On wikipedia you can find more interesting links.
Prompt
Here you can see a very beautiful zsh prompt. I have to admit I just copied the script from here. I'll change something one day... at the moment I'm to lazy (and I'm also happy I managed to get accented characters work with bash and Terminal.app).
Here you can see how secondary prompts can be useful when writing scripts in the shell. By the way, every script you enter is fully line editable in the shell.
Ok, here nothing new.
