I can understand, having been bitten by it many times myself (not only is it counter-intuitively expanded inside double quotes, and not only does it not do what you wanted, but it does not insert the command into the history, so you cannot even go back to fix it easily). > Does this feature work when running a test explicitly using > "bash <name of test>"?

The reason is that the "!" is part of history expansion, which is only enabled by default for interactive shells. > If it works everywhere, this patch would help me conquer my fear of > exclamation points in git's tests, which would be a comfort to me and > a very good thing. As far as I know, "!" should be safe in a non-interactive shell script. -Peff -- 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
