I’ve been wondering whether there is a good “git export” solution that creates a copy of a tree without the
.git repository directory. There are at least three methods I know of:
git clonefollowed by removing the
git checkout-indexalludes to this functionality but starts with “Just read the desired tree into the index…” which I’m not entirely sure how to do.
git-exportis a third party script that essentially does a
git cloneinto a temporary location followed by
rsync --exclude='.git'into the final destination.
None of these solutions really strike me as being satisfactory. The closest one to
svn export might be option 1, because both those require the target directory to be empty first. But option 2 seems even better, assuming I can figure out what it means to read a tree into the index.
Probably the simplest way to achieve this is with
git archive. If you really need just the expanded tree you can do something like this.
git archive master | tar -x -C /somewhere/else
Most of the time that I need to ‘export’ something from git, I want a compressed archive in any case so I do something like this.
git archive master | bzip2 >source-tree.tar.bz2
git archive --format zip --output /full/path/to/zipfile.zip master
git help archive for more details, it’s quite flexible.
Be aware that even though the archive will not contain the .git directory, it will, however, contain other hidden git-specific files like .gitignore, .gitattributes, etc. If you don’t want them in the archive, make sure you use the export-ignore attribute in a .gitattributes file and commit this before doing your archive.

Note: If you are interested in exporting the index, the command is
git checkout-index -a -f --prefix=/destination/path/
