is there is any harm if I delete merged branches from a fork?
and, if I do the same for unmerged (old, stalled) branches also?
and if I deleted a branch can I put it back again in the fork from upstream? how? Thanks!
No particular harm no, the changes you make to a fork are completely independent of the changes to the upstream. Obviously if you delete an unmerged branch that you created in your fork and isn't mirrored in the upstream, you won't (easily) be able to get it back.
Sure you can pull a branch from upstream into your branch, you just need to pull it from upstream to your local repo first and then push it to your fork. Assuming you have the fork remote set up as "origin" and the upstream set up as "upstream" (git remote add upstream <upstream URL>
if you don't have that):
git fetch upstream/branchname
git checkout branchname
git push -u origin branchname
@ryanc414 Thanks a lot!
To run this script on macOS, you need to first install the GNU version of
xargs
viabrew install findutils
, then change line 13 to callgxargs
(or update your PATH so that the GNU version ofxargs
comes before the BSD version).
