Command to get latest Git commit hash from a branch

Question

How can I check with the command line the latest commit hash of a particular Git branch

User · Answer

Try using git log -n 1 after doing a git checkout branchname  This shows the commit hash  author  date and commit message for the latest commit   Perform a git pull origin branchname first  to make sure your local repo matches upstream   If perhaps you would only like to see a list of the commits your local branch is behind on the remote branch do this   git fetch origin git cherry localbranch remotebranch   This will list all the hashes of the commits that you have not yet merged into your local branch

In a comment you wrote      i want to show that there is a difference in local and github repo   As already mentioned in another answer  you should do a git fetch origin first  Then  if the remote is ahead of your current branch  you can list all commits between your local branch and the remote with  git log master  origin master --stat   If your local branch is ahead   git log origin master  master --stat   --stat shows a list of changed files as well   If you want to explicitly list the additions and deletions  use git diff   git diff master origin master

Note that when using  git log -n 1  branch name   option  -n returns only one line of log but order in which this is returned is not guaranteed   Following is extract from git-log man page              Commit Limiting  Besides specifying a range of commits that should be listed using the special notations explained in the     description  additional commit limiting may be applied   Using more options generally further limits the output  e g  --since  lt date1 gt  limits to commits newer than  lt date1 gt   and using it with --grep  lt pattern gt  further limits to commits whose log message has a line that matches  lt pattern gt    unless otherwise noted   Note that these are applied before commit ordering and formatting options  such as --reverse   - lt number gt  -n  lt number gt

Use git ls-remote git   github com  lt user gt   lt project gt  git  For example  my trac-backlog project gives      git ls-remote git   github com jszakmeister trac-backlog git 5d6a3c973c254378738bdbc85d72f14aefa316a0    HEAD 4652257768acef90b9af560295b02d0ac6e7702c    refs heads 0 1 x 35af07bc99c7527b84e11a8632bfb396823326f3    refs heads 0 2 x 5d6a3c973c254378738bdbc85d72f14aefa316a0    refs heads master 520dcebff52506682d6822ade0188d4622eb41d1    refs pull 11 head 6b2c1ed650a7ff693ecd8ab1cb5c124ba32866a2    refs pull 11 merge 51088b60d66b68a565080eb56dbbc5f8c97c1400    refs pull 12 head 127c468826c0c77e26a5da4d40ae3a61e00c0726    refs pull 12 merge 2401b5537224fe4176f2a134ee93005a6263cf24    refs pull 15 head 8aa9aedc0e3a0d43ddfeaf0b971d0ae3a23d57b3    refs pull 15 merge d96aed93c94f97d328fc57588e61a7ec52a05c69    refs pull 7 head f7c1e8dabdbeca9f9060de24da4560abc76e77cd    refs pull 7 merge aa8a935f084a6e1c66aa939b47b9a5567c4e25f5    refs pull 8 head cd258b82cc499d84165ea8d7a23faa46f0f2f125    refs pull 8 merge c10a73a8b0c1809fcb3a1f49bdc1a6487927483d    refs tags 0 1 0 a39dad9a1268f7df256ba78f1166308563544af1    refs tags 0 2 0 2d559cf785816afd69c3cb768413c4f6ca574708    refs tags 0 2 1 434170523d5f8aad05dc5cf86c2a326908cf3f57    refs tags 0 2 2 d2dfe40cb78ddc66e6865dcd2e76d6bc2291d44c    refs tags 0 3 0 9db35263a15dcdfbc19ed0a1f7a9e29a40507070    refs tags 0 3 0      Just grep for the one you need and cut it out      git ls-remote git   github com jszakmeister trac-backlog git        grep refs heads master   cut -f 1 5d6a3c973c254378738bdbc85d72f14aefa316a0   Or  you can specify which refs you want on the command line and avoid the grep with      git ls-remote git   github com jszakmeister trac-backlog git refs heads master        cut -f 1 5d6a3c973c254378738bdbc85d72f14aefa316a0   Note  it doesn t have to be the git    URL  It could be https    or git github com  too   Originally  this was geared towards finding out the latest commit of a remote branch  not just from your last fetch  but the actual latest commit in the branch on the remote repository    If you need the commit hash for something locally  the best answer is   git rev-parse branch-name   It s fast  easy  and a single command   If you want the commit hash for the current branch  you can look at HEAD   git rev-parse HEAD

git log -n 1  branch name    branch name  may be remote or local branch  is optional  Without branch name  it will show the latest commit on the current branch   For example   git log -n 1 git log -n 1 origin master git log -n 1 some local branch  git log -n 1 --pretty format   H    To get only hash value of commit
