Gerrit: Please see below for a summary of why I think this is a "dash" bug. I clone the bug instead of just reassigning it because I will implement a workaround in my package and will close the bug in the changelog accordingly. I'm sorry, but the test syntax is absolutely OK for a Debian system (see "man test") and it certainly is no "bashism". The problem is that dash wants to override the normal "test" binary but doesn't allow it's full syntax. Dash is the only shell I know of that doesn't allow use of the "-nt" (newer than) test. In other words: I believe that this needs to be fixed in dash, not in my build script. I use documented syntax of the "test" binary. If dash insists on overriding that binary with its own builtin implementation, it should provide the full functionality of the test binary shipped with Debian. This has been discussed before IIRC, but I can't find the discussion anymore.... However, I will (for now) call /usr/bin/test explicitly, which _should_ avoid the test builtin, but this is a stupid workaround to a (IMHO) stupid behaviour of a so-called standard-adherent shell. To summarize: Debian includes a "test" binary which documents support of the "-nt" comparator (see "man dash",[1]). "dash" overrides that with a builtin which doesn't support "-nt". Posix doesn't mandate a "test" built-in (see [2] and [3]), so the implementation of such a built-in is in excession of POSIX requirements. dash implements a posix-minimal version of "test", which is less than one can rightfully expect from a Debian system (-nt is documented in the manpage of "test).
