I appreciate your efforts of coming up with some sh styleguide. A side note to that, I prefer calling test explicitely, instead of using the weirdo [ ] symlinks in while/if statements. Nevertheless, after an excursion to sh for several years, I'm kind of favouring 9base/rc again, after all. For stali I now tend to adopt rc as primary scripting language for the target system as well. For the build host environment I would rather stick to sh+make instead of rc+mk. We have to live with the fact that a build host environment is poisoned with crap bloat to hell anyways. But for ideal target system, we should stick to technologies that have been designed with clarity and cleanliness in mind. rc is the perfect example for a decent shell environment. When I started 9base and Uriel started werc and other rc-based stuff, we concluded that one cannot really write portable scripts with sh. You have to rely on a defined userland. The Plan 9 derived userland offers this definition. I agree that sbase goes into a similar direction, but the danger remains when using sh, that some stuff will end up in pretty mixed environments. For serious stuff like werc, rc was the right choice, because it relies on this definite userland environment and hence does not allow for ambiguity. I just wanted to mention this, as this is one of my very recent decisions about stali's future. BR, Anselm
