git tag Management

When we publish a version, we usually make a tag in the repository, so that the only version of the tag is determined, in the future whenever, the version of a tag is

Take out the historical version of the tagged moment, so the tag is a snapshot of the repository, and Git's tag is a snapshot of the repository, but it's actually a pointer to a commit.

(like a branch, but the branch can be moved, the label cannot be moved), so creating and deleting a label is done in a flash.

Tagging in Git is easy, first switching to a branch that needs to be labeled:

Enter git tag name to make a new tag:

$ git Tag v1.0

You can use the command git tag to see all the tags:

$ git tag
v1.0

The default tag is on the most recently committed commit. Sometimes, what if you forget to tag?

The way to do this is to find the commit ID of the history commit, and then hit it.

$ git log--pretty=oneline--abbrev-commit
Dbfc0ee Merge bug Fix 119
B4d16ef Bug 119 had fix
8e64728 Merge with No-ff
4F4F23A Dev Commit
F3D8F1E Branch Merge
4BB4C5A Master Branch Merge test
Cccee34 Newbranch First Commit
0D0BBCA Dev First Commit
D5aea29 Master First Commit
023EE21 Initial Commit

For example, to "branch merge" This commit tag, it corresponds to the commit ID is "f3d8f1e", the typing command:

$ git tag v0.9 f3d8f1e

See all the tabs below:

$ git tag

Note: Tags are not listed in chronological order, but are listed alphabetically, and can be viewed with git show tagname:

$ git Show v1.0

You can also create a label with a description, specify the label name with-A,-m to specify the description text:

$ git tag-s v0.2-m "signed version 0.2 released" 8e64728
