Being able to run both might turn out to be useful. I second that. Having a --post-order=<command/script> switch will give us much more flexibility. For ease of use we could allow --post-order without command to switch the meaning of the main command. So a final solution would have these switches: git submodule foreach ... [--pre-order[=<command>]] [--post-order[=<command>]] [<command>] If only --pre-order without argument is given the command will be executed pre-order. If only --post-order the command will be executed post-order. If both are given its an error and so on... There are some combinations we would need to catch as errors but this design should allow a step by step implementation: 1. just the --post-order switch 2. --post-order with argument switch 3. --pre-order (including argument) for symmetry of usage Cheers Heiko -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
