A two-part shell (half library, half REPL) for ULOS 2. Its design is heavily inspired by https://github.com/zserge/luash.
local sh = require("sh")
LuaSH can compile basic Bourne-stype statements:
sh.compile("ls /bin | grep .*s.*") = sh.ls("/bin"):grep(".*s.*")
This is not perfect, and it is recommended to simply use LuaSH's features directly. For example, ls /bin | grep $(ls /lib) $filter = sh.ls("/bin"):grep(sh.split(sh.ls("/lib")), sh.getenv("filter")) - so even if there are multiple files in /lib, only the first will be passed due to how Lua's varargs work.
