i have develop branch , feature branch in git repo. added commit develop , want commit merged feature branch. if this git checkout feature git merge develop i end merge commit. since i'll merging new commits on develop feature branch frequently, i'd avoid these unnecessary merge commits. saw answer suggested doing git rebase develop ends rewinding branch way far , rebase fails. update: ended doing was git checkout feature git merge develop # creates merge commit don't want git rebase # gets rid of merge commit keeps commits develop want git push update: noticed original commit on develop gets different hash when merge rebase feature branch. don't think that's want because i'll merge feature develop , i'm guessing won't play nice. to integrate 1 branch another, have either merge or rebase. since it's safe rebase commits aren't referenced anywhere else (not merged other local branches; not pushed remote), it's better
