Busybox[1] is a single executable that provides the functionality of many of the basic UNIX userspace utilities (like ls etc.) depending on what name it's called with. You can simply symlink ls etc. to busybox and it'll work. It's very useful for embedded situations since you can just drop in a single executable and get all the basic things for free. > Any pointers... ? Apropos SBCs, I recently bought a beagle board[2] for someone who was working on a project. It's ARM based and is quite powerful. It has tons of ports you can connect stuff to. I think he booted it with something called Angstrom[3] and then we connected to it via. serial and got a complete environment. It's powerful enough to run a proper small GNU/Linux. I don't think you need busybox and things like that. This is the only one *I* know of. You can order it in Bangalore from Tenet technologies[4] and it costs a little less than 10k. > the search continues :)) > > Recently I have realized that almost all problems in this world...are > a form of search...No wonder the company that mastered search is a > "G"iant now. My take is different. I recently met someone famous but I didn't recollect what he was famous for. He was standing about a metre away from me and instead of starting a conversation - something which I can do fairly well, I actually googled for his name to find out more about him. Later in the evening, I seriously wished that I didn't have the ability to just "search" for him. The conversation would have been a lot more interesting.
