I'm finding that I'm doing this fairly often -- I was just wondering if anyone had anything like a 'git-inject-tarball' script they'd written up. Thanks, Anand [1]: http://www.kernel.org/pub/software/scm/git/docs/everyday.html ``` ## Johannes Schindelin, 2005-12-28 11:42 Subject: Re: git-inject-tarball Message-ID: URL: https://gitlist.dev/e/Pine.LNX.4.63.0512281230070.15184%40wbgn013.biozentrum.uni-wuerzburg.de In-Reply-To: ``` Hi, On Wed, 28 Dec 2005, Anand Kumria wrote: > > Hi, > > In the Everyday commands[1], there is an example of of extracting a > tarball and then working with it.

Something like this? -- snip -- #!/bin/sh TARFILE="$1" test -z "$TARFILE" && TARFILE=- git-ls-files -z | xargs -0 rm tar xvf "$TARFILE" | xargs git add git-update-index --remove $(git-ls-files) -- snap -- Notes: - this updates the index to match the given tarfile, you still have to commit yourself - it does not handle compressed tarfiles (you have to do something like "cat bla.tar.gz | gzip -d | sh git-untar.sh") - it does not remove empty directories (i.e. if the current index contains a file "a/b", and the tarfile does not, and the directory "a" is now empty, this is not handled) - usually, tarfiles contain files inside a subdirectory. There is no facility to strip the subdirectory Hth, Dscho ``` ## Simon Richter, 2005-12-28 15:51 Subject: Re: git-inject-tarball Message-ID: <43B2B474.1000603@hogyros.de> URL: https://gitlist.dev/e/43B2B474.1000603%40hogyros.de In-Reply-To: ``` Hi, Johannes Schindelin wrote: > Something like this? > -- snip -- > #!/bin/sh > > TARFILE="$1" > test -z "$TARFILE" && TARFILE=- > > git-ls-files -z | xargs -0 rm > tar xvf "$TARFILE" | xargs git add > git-update-index --remove $(git-ls-files) > -- snap -- Well, the most important thing for such a tool IMO would be that it wouldn't overwrite any uncommitted changes, so it's not as trivial as it seems.

Ah, but that's easy: test -z "$(git-diff-index --name-only HEAD)" || exit 1 (This is just the idea; you should also output an error message.) Hth, Dscho ```
