git/repo cheat sheet

  • force push:¬†git push -f github HEAD:nova
  • get all repo diff: repo diff -u
  • partial add file: git add -p file
  • rebasing squash etc.:¬†git rebase -i hash-commit-before
  • get all patches: git format-patch BRANCH
  • get last commit as a patch: git format-patch -1
  • tig is my favorite git client (can do cherry-pick reverts etc and supports bindings)
  • diff between two tags or old tag and current file
git diff v3.12 v4.7 -- src/leanback/java/com/archos/mediacenter/video/leanback/MainFragment.java
git show v3.10:src/leanback/java/com/archos/mediacenter/video/leanback/MainFragment.java > MainFragment-v3.10.java
meld MainFragment-v3.10.java ./src/main/java/com/archos/mediacenter/video/leanback/MainFragment.java
  • maintain branch up to speed with master before merging i.e v4-jcifsng with v4 (when ready merge back the branch to master)
git checkout v4-jcifsng
git rebase v4 v4-jcifsng
git push -f github HEAD:v4-jcifsng
