How to get the changes on a branch in Git

Question

What is the best way to get a log of commits on a branch since the time it was branched from the current branch  My solution so far is   git log   git merge-base HEAD branch   branch   The documentation for git-diff indicates that git diff A   B is equivalent to git diff   git-merge-base A B  B  On the other hand  the documentation for git-rev-parse indicates that r1   r2 is defined as r1 r2 --not   git merge-base --all r1 r2    Why are these different  Note that git diff HEAD   branch gives me the diffs I want  but the corresponding git log command gives me more than what I want   In pictures  suppose this             x---y---z---branch           ---a---b---c---d---e---HEAD   I would like to get a log containing commits x  y  z    git diff HEAD   branch gives these commits however  git log HEAD   branch gives x  y  z  c  d  e

In the context of a revision list  A   B is how git-rev-parse defines it  git-log takes a revision list  git-diff does not take a list of revisions - it takes one or two revisions  and has defined the A   B syntax to mean how it s defined in the git-diff manpage  If git-diff did not explicitly define A   B  then that syntax would be invalid  Note that the git-rev-parse manpage describes A   B in the  Specifying Ranges  section  and everything in that section is only valid in situations where a revision range is valid  i e  when a revision list is desired    To get a log containing just x  y  and z  try git log HEAD  branch  two dots  not three   This is identical to git log branch --not HEAD  and means all commits on branch that aren t on HEAD

I found  git diff  lt branch with changes gt   lt branch to compare to gt    more useful  since you don t only get the commit messages but the whole diff  If you are already on the branch you want to see the changes of and  for instance  want to see what has changed to the master  you can use   git diff HEAD master

git cherry branch  newbranch    does exactly what you are asking  when you are in the master branch   I am also very fond of   git diff --name-status branch  newbranch    Which isn t exactly what you re asking  but is still very useful in the same context

To see the log of the current branch since branching off master   git log master     If you are currently on master  to see the log of a different branch since it branched off master   git log    other-branch

With Git 2 30  Q1 2021    quot git diff A   B man  quot  learned  quot git diff --merge-base A B man   which is a longer short-hand to say the same thing  Thus you can do this using git diff --merge-base  lt branch gt  HEAD  This should be equivalent to git diff  lt branch gt    HEAD but without the confusion of having to use range-notation in a diff

git log --cherry-mark --oneline from branch   to branch    3dots  but sometimes it shows     instead of

What you want to see is the list of outgoing commits  You can do this using  git log master  branchName    or   git log master  branchName --oneline   Where I assume that  branchName  was created as a tracking branch of  master    Similarly  to see the incoming changes you can use   git log branchName  master

Similar to several answers like Alex V s and NDavis  but none of them are quite the same   When already in the branch in question  Using   git diff master      Which combines several features    it s super short shows the actual changes   Update   This should probably be git diff master  but also this shows the diff  not the commits as the question specified

Throw a -p in there to see some FILE CHANGES  git log -p master  branch   Make some aliases   alias gbc  git branch --no-color   sed -e          d  -e  s             1     alias gbl  git log -p master    gbc      See a branch s unique commits   gbl

This is similar to the answer I posted on  Preview a Git push  Drop these functions into your Bash profile    gbout - git branch outgoing gbin  - git branch incoming   You can use this like    If on master  gbin branch1   lt -- this will show you what s in branch1 and not in master If on master  gbout branch1  lt -- this will show you what s in master that s not in branch 1   This will work with any branch   function parse git branch     git branch --no-color 2 gt   dev null   sed -e         d  -e  s           1      function gbin       echo branch    1   has these commits and     parse git branch    does not     git log    1 --no-merges --format   h   Author  an   Date  ad    s  --date local    function gbout       echo branch     parse git branch    has these commits and    1   does not     git log  1   --no-merges --format   h   Author  an   Date  ad    s  --date local
