I've found the -n switch to git clone useful and would like
something similar when reconstructing my "branch hierarchies".
Upto now I only know about "git checkout" (with or without -b) to
switch the current branch. As said it's not really essential, but I
was expecting there would be something like a "branch --switch".
Did I overlook it?
Perusing git-checkout points me to git-symbolic-ref to update the
HEAD ref to a new branch:
git symbolic-ref HEAD refs/heads/<branch>
However, I'm somewhat confused as to why you'd want HEAD and the
working directory to get out of sync. It would cause any further
commits to have broken history information. If you want to make the
content of one branch ($branchA) the same as the other ($branchB),
you should do something like:
git checkout -b temp $branchB # Get content from branchB
git merge -s ours $branchA # Merge history (not content) from
branchA
git branch -M $branchA # Make this new merge branchA
This would be significantly simpler if there was a "theirs" merge
strategy "git checkout $branchA; git merge -s theirs $branchB", but
there isn't. Should be simple to write if you really need it though.
