git tag -a 1.0.1 commit_id -m 'Version 1.0.1'

Push all tags to remote repository

git push --tags

Switch to tag

git checkout tag_name

Delete local tag

git tag -d v.0.4

Delete remote tag

git push origin :v0.4

Branches

List all local branches

git branch

List all remote branches

git branch -r

List all local and remote branches

git branch -a

Create branch from current

git branch branch_name

Create branch and switch to it

git checkout -b branch_name

Create branch from commit

git branch branch_name commit_id

Create branch from commit and switch to it

git checkout -b branch_name commit_id

Merge branch_name into current branch

git merge branch_name

git fetch -p

git remote update origin --prune

Merging

Fetch changes from remote repository and apply them locally

git fetch origin
git reset --hard origin/master

Discard changes in a file

git checkout v1.2.3 -- filename         # tag v1.2.3
git checkout stable -- filename         # stable branch
git checkout origin/master -- filename  # upstream master
git checkout HEAD -- filename           # the version from the most recent commit
git checkout HEAD^ -- filename          # the version before the most recent commit

git rm --cached git ls-files -i --exclude-standard
