I have also expected that\nbehavior in the past, and found it surprising when it did not.\n\nWhat git am does is apply relative to the root of the repository. If\nyou'd instead like to apply to a specific subdirectory of the\nrepository, you can use the --directory option to specify to which\ndirectory your patch should apply.\n\nThis is the behavior of git apply, which underpins git am. However,\noutside of a repository, it _does_ apply relative to the current\ndirectory, since there's no repository root to consider. I, at least,\nfound this confusing, but that's how it works.\n-- \nbrian m. carlson: Houston, Texas, US\nOpenPGP: https://keybase.io/bk2204\n"},{"id":"395066","messageId":"CAHp75Vfuuth05wn-0x_AZa_LFSmQMHB6LGM5b4KNMoaxce1S-g@mail.gmail.com","threadId":"53182","inReplyTo":"20200408011830.GA6549@camp.crustytoothpaste.net","subject":"Re: subtle bug in git-am","fromName":"Andy Shevchenko","fromEmail":"andy.shevchenko@gmail.com","sentAt":"2020-04-08T09:29:43Z","receivedAt":"2020-04-08T09:29:54Z","isPatch":false,"sender":{"key":"andy.shevchenko@gmail.com","avatar":"https://gravatar.com/avatar/e7fccbe23f198167f8b4c119a3a8729d3cec5b3268293ffe07ee15a50c39938b?d=mp&s=160"},"body":"On Wed, Apr 8, 2020 at 4:19 AM brian m. carlson\n wrote:\n>\n> On 2020-04-07 at 18:48:23, Andy Shevchenko wrote:\n> > Hi!\n> >\n> > What I would like to do is to apply patch from one repository to another with\n> > same files but *different directory structure*.\n> >\n> > When I try to change directory in the target repo to the folder of files, I run\n> > git-am -p5 my_cool_patch.patch.\n> >\n> > Instead of the expected result (files and their contents is the same!)
