Rebase on dev branch

If the dev branch has changed since you started working on it, please rebase your work after the current dev.

On your working branch mybranch:

git rebase dev mybranch

In case of conflict:

 git mergetool
 git rebase --continue

When everything's fine on your local branch, force push to your myOrigin remote:

git push myOrigin --force-with-lease

To cancel everything:

git rebase --abort

Squashing commits

git rebase -i origin/dev

• Replace pick by fixup on the commits you want squashed out
• Replace pick by reword on the first commit if you want to change the commit message
• Save the file and quit your editor

Force push to your myOrigin remote:

git push myOrigin --force-with-lease
