The thing is, I'm generally interested in signatures when using git interactively (that's why I enabled log.showSignature globally). But then I have a scripted usecase that has a tag name, and needs to query the corresponding commit hash, and in that context, I don't care about signatures at all. The docs for git show say that %H expands to the commit hash, which is exactly what I want. I didn't know about the %G formats, but after a quick look at the docs, I don't think they solves that problem. I can work around this problem by using "export GIT_CONFIG_GLOBAL=/dev/null" in the script, which I guess might be generally good practice when using git in scripts? But I still think it would be useful if there were an easy and reliable way to get from tag to commit hash, regardless of the user's config settings. Regards, /Niels Möller
