Combining multiple git repositories

Question

Let\'s say I\'ve got a setup that look something like

phd/code/
phd/figures/
phd/thesis/

For historical reasons, these all have their own g

Answer 1

Perhaps, simply (similarly to the previous answer, but using simpler commands) making in each of the separate old repositories a commit that moves the content into a suitably named subdir, e.g.:

$ cd phd/code
$ mkdir code
# This won't work literally, because * would also match the new code/ subdir, but you understand what I mean:
$ git mv * code/
$ git commit -m "preparing the code directory for migration"

and then merging the three separate repos into one new, by doing smth like:

$ cd ../..
$ mkdir phd.all
$ cd phd.all
$ git init
$ git pull ../phd/code
...

Then you'll save your histories, but will go on with a single repo.
