How to tag an older commit in Git

Question

We are new to git  and I want to set a tag at the beginning of our repository   Our production code is the same as the beginning repository  but we ve made commits since then  A tag at the beginning would allow us to  roll back  production to a known  stable state   So how to add a tag to an arbitrary  older commit

Example   git tag -a v1 2 9fceb02 -m  Message here    Where 9fceb02 is the beginning part of the commit id   You can then push the tag using git push origin v1 2   You can do git log to show all the commit id s in your current branch   There is also a good chapter on tagging in the Pro Git book   Warning  This creates tags with the current date  and that value is what will show on a GitHub releases page  for example    If you want the tag to be dated with the commit date  please look at another answer

The simplest way to do this is  git tag v1 0 0 f4ba1fc git push origin --tags  with f4ba1fc being the beginning of the hash of the commit you want to tag and v1 0 0 being the version you want to tag

OK  You can simply do   git tag -a  lt tag gt   lt commit-hash gt    So if you want to add tag  1 0 2 to commit e50f795  just simply do   git tag -a 1 0 2 e50f795   Also you add a message at the end  using -m  something like this   git tag -a 1 0 2 e50f795 -m  my message    After all  you need to push it to the remote  to do that  simply do   git push origin 1 0 2    If you have many tags which you don t want to mention them one by one  just simply do   git push origin --tags   to push all tags together     Also  I created the steps in the image below  for more clarification of the steps     You can also dd the tag in Hub or using tools like SourceTree  to avoid the previous steps  I logged-in to my Bitbucket in this case and doing it from there    Go to your branch and find the commit you want to add the tag to and click on it       In the commit page  on the right  find where it says No tags and click on the   icon       In the tag name box  add your tag       Now you see that the tag has successfully created

Just the Code   Set the HEAD to the old commit that we want to tag git checkout 9fceb02    temporarily set the date to the date of the HEAD commit  and add the tag GIT COMMITTER DATE  quot   git show --format  aD   head -1  quot    git tag -a v1 2 -m quot v1 2 quot     set HEAD back to whatever you want it to be git checkout master  Details The answer by  dkinzer creates tags whose date is the current date  when you ran the git tag command   not the date of the commit  The Git help for tag has a section  quot On Backdating Tags quot  which says   If you have imported some changes from another VCS and would like to add tags for major releases of your work  it is useful to be able to specify the date to embed inside of the tag object  such data in the tag object affects  for example  the ordering of tags in the gitweb interface  To set the date used in future tag objects  set the environment variable GIT COMMITTER DATE  see the later discussion of possible values  the most common form is  quot YYYY-MM-DD HH MM quot    For example    GIT COMMITTER DATE  quot 2006-10-02 10 31 quot  git tag -s v1 0 1   The page  quot How to Tag in Git quot  shows us that we can extract the time of the HEAD commit via  git show --format  aD    head -1    gt  Wed  12 Feb 2014 12 36 47 -0700  We could extract the date of a specific commit via  GIT COMMITTER DATE  quot   git show 9fceb02 --format  aD   head -1  quot    git tag -a v1 2 9fceb02 -m  quot v1 2 quot   However  instead of repeating the commit twice  it seems easier to just change the HEAD to that commit and use it implicitly in both commands  git checkout 9fceb02   GIT COMMITTER DATE  quot   git show --format  aD   head -1  quot  git tag -a v1 2 -m  quot v1 2 quot

This is an old question  and the answers already given all work  but there s also a new option which can be considered   If you re using SourceTree to manage your git repositories  you can right-click on any commit and add a tag to it  With another mouseclick you can also send the tag straight to the branch on origin
