git ls-tree -r <revision-id>git cat-file -p <file-id>

Get file-id’s for all the files in/at a specific revision - use this id for “cat-file” Use <revision-id>^ to get the revision prior to the one specified - to get, for example, the id of a file deleted at <revision-id>. Dumps the file contents to stdout (see previous git ls-tree entry - these two together make a svn -r <rev> url://path/file). (Thanks to http://www.gelato.unsw.edu.au )|
