Yes. If I have enough time, I may perhaps even today add a link to it on picobsd home page. I took it from Minix distribution. It does most things the /bin/sh does (though I haven't tested it thoroughly yet), and it's small (ca. 40kB). The most obvious deficiency is lack of support for user-defined functions, and this is a serious one. I plan also to port an editor from Minix - it comes out slightly smaller than our ee.
