You can check if the name is valid with git check-ref-format This page contains the constraints on a valid name. Quoted from the page (possibly outdated in the future): They can include slash / for hierarchical (directory) grouping, but no slash-separated component can begin with a dot . or end with the sequence .lock. They … Read more
git for-each-ref tells you what each ref is to by default, its id and its type. To restrict it to just tags, do git for-each-ref refs/tags. [T]he output has three fields: The hash of an object, the type of the object, and the name in refs/tags that refers to the object. A so-called “lightweight” tag … Read more
This always worked for me: git log –tags –simplify-by-decoration –pretty=”format:%ci %d” Consult the “PRETTY FORMATS” section of the git-log manpage for details of the format string if you want a different date formatting.
To get git tags with the SHA1 hash of the Tag object, you can run: git show-ref –tags The output will then look something like: 0e76920bea4381cfc676825f3143fdd5fcf8c21f refs/tags/1.0.0 5ce9639ead3a54bd1cc062963804e5bcfcfe1e83 refs/tags/1.1.0 591eceaf92f99f69ea402c4ca639605e60963ee6 refs/tags/1.2.0 40414f41d0fb89f7a0d2f17736a906943c05acc9 refs/tags/1.3.0 Each line is the SHA1 hash of the tag, followed by the tag name prefixed with refs/tags/. If you want the SHA1 … Read more
A tag is immutable. Whereas you can create a branch named “1.0.0” – you, or anyone with commit rights, can also then simply push to that branch (deliberately or not) and change what 1.0.0 means. You can’t do that with a tag, once you create a tag – that’s it; Tag 1.0.0 means exactly that … Read more
You can push an ’empty’ reference to the remote tag name: git push origin :tagname Or, more expressively, use the –delete option (or -d if your git version is older than 1.8.0): git push –delete origin tagname Note that git has tag namespace and branch namespace so you may use the same name for a … Read more
Edit, 24 Nov 2016: this answer is apparently popular, so I am adding a note here. If you replace a tag on a central server, anyone who has the old tag—any clone of that central-server repository that already has the tag—could retain its old tag. So while this tells you how to do it, be … Read more
Okay, first a few terms slightly oversimplified. In git, a tag (like many other things) is what’s called a treeish. It’s a way of referring to a point in in the history of the project. Treeishes can be a tag, a commit, a date specifier, an ordinal specifier or many other things. Now a branch … Read more
git push –tags production
You could do this: git push –tags
