Which is all nice and pretty, when it works, yes. But whilst my die trick is a lot smarter than Aron's, it's still not entirely reliable. In particular, if you do $(foo || die ; bar ), there's a race condition which means bar might be executed anyway, and if you do enough arcane shell voodoo then the die might still end up being lost completely (we had this with eselect at one point...). So basically, don't rely upon it working. It means you're much less likely to be screwed over if you *do* accidentally do a subshell die, but it doesn't mean that subshell die works. -- Ciaran McCreesh Mail : ciaranm at ciaranm.org Web : http://ciaranm.org/ Paludis is faster : http://ciaranm.org/show_post.pl?post_id=61
