Does git tag create a commit?
This will tag the passed commit instead of defaulting to HEAD.
To gather a list of older commits execute the git log command.
Executing the above git tag invocation will create a new annotated commit identified as v1.
2 for the commit we selected in the previous git log example..
What does a git commit contain?
The commit object contains the directory tree object hash, parent commit hash, author, committer, date and message. I’ll use git cat-file to show the contents of the hashed files in . git/objects , but cat-file is a relatively obscure git command that you will probably not need in your daily git work.
How do you git tag a commit?
In order to create a Git tag for the last commit of your current checked out branch, use the “git tag” command with the tag name and specify “HEAD” as the commit to create the tag from. Similarly, if you want your tag to be annotated, you can still use the “-a” and “-m” options to annotate your tag.
Can a commit be on more than one branch?
Your best option would be to commit to one of your branches (or a master branch) and then either merge the commit into the others one by one, or cherry-pick the commit into each of the other branches.
What is a git tag vs branch?
The difference between tags and branches are that a branch always points to the top of a development line and will change when a new commit is pushed whereas a tag will not change. Thus tags are more useful to “tag” a specific version and the tag will then always stay on that version and usually not be changed.
Are git tags branch specific?
Tags and branch are completely unrelated, since tags refer to a specific commit, and branch is a moving reference to the last commit of a history. … So when you tag a commit, git doesn’t care which commit or branch is checked out, if you provide him the SHA1 of what you want to tag.
What happens when we do git commit?
Well, basically git commit puts your changes into your local repo, while git push sends your changes to the remote location. git push is used to add commits you have done on the local repository to a remote one – together with git pull , it allows people to collaborate.
Do git tags have to be unique?
Tags are completely separate from branches, so how you choose to handle tags doesn’t depend on how you choose to handle branches. You can apply a tag to branch E’ and safely delete test_branch , without losing the code in E’ .
How do I tag an old commit?
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 “YYYY-MM-DD HH:MM”). 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.
How do you push a tag?
Sharing Tags You will have to explicitly push tags to a shared server after you have created them. This process is just like sharing remote branches — you can run git push origin

What is a git commit SHA?
The SHA1 of the commit is the hash of all the information. And because this hash is unique to its content, a commit can’t change. If you change any data about the commit, it will have a new SHA1. Even if the files don’t change, the created date will. A commit is a code snapshot.
