That phrase gave me some trouble the first time I read it\ntoo. All it means is 'do a `git checkout` of the branch that you want\nto export'. `git checkout-index` will then do an export of the\ncontents the branch that you currently have checked out.\n\nJunio and Dscho's comments are possibly salient as well.\n\n-- \n\nIn Christ,\n\nTimmy V.\n\nhttp://burningones.com/\nhttp://five.sentenc.es/ - Spend less time on e-mail\n"},{"id":"120249","messageId":"4A8122BC.7030009@drmicha.warpmail.net","threadId":"20525","inReplyTo":"200908101822.59940.thomas@koch.ro","subject":"Re: [Feature Request] git export","fromName":"Michael J Gruber","fromEmail":"git@drmicha.warpmail.net","sentAt":"2009-08-11T07:50:20Z","receivedAt":"2009-08-11T07:50:20Z","isPatch":false,"sender":{"key":"git@grubix.eu","avatar":"https://avatars.githubusercontent.com/u/233215?v=4"},"body":"Thomas Koch venit, vidit, dixit 10.08.2009 18:22:\n> could you please provide a simple solution to save a tree object into an \n> arbitrary location?\n> I found some hints, that it would be possible by missusing either git \n> checkout-index or git-archive, but I think that it shouldn't require that much \n> GIT FU to do such a simple thing.\n> \n> Thanks,\n> \n> Thomas Koch, http://www.koch.ro\n\nTo serve you with an explicit command line, it's really only\n\ngit archive HEAD | tar -C wheretoexport/ -xf-\n\nwhich you need to issue from within your git repo. Instead of HEAD, you\ncan use any \"treeish\", for example the name of a branch, which need not\nbe checked out. You can add path arguments after the treeish if you want\nto export only parts of your repo.\n\nNote that in true unix philosophy, git archive does the (git specific)\nexporting only and leaves the importing into the file system (saving) to\nthe proper tool. I mean, would you rather use cp -r or pipes with tar\n-x/tar -c or cpio -i/-o in order to copy a tree? ;)\n\nCheers,\nMichael\n"}]}
