Git: tagging old commits

By default ‘git tag’ command will create a tag on the commit that HEAD is pointing to.

We can create a tag to previous commits using below syntax.

Syntax

git tag -a {version_name} {snapshot_id} -m "{message}"

$git log --pretty=oneline
5d1e6966e845a4709372b9af02d3ac32ae8026f4 (HEAD -> master) Add project description
2c389dc281395917105cf51f48bcc20c27ba51f4 Add author details
a143c88dcab536c36a1509cbc0819bcd5e4602ce Add test line to readme.md
1dcf079f688877f16c8f54b1b9e57fba19216e84 (tag: v1.0) add description to readme.md
546599eaf071a6a634ca36a20047f5e3a3925337 (origin/master) Add readme.md file

Let’s create new tag to the second latest commit using below syntax.

git tag -a v1.1 2c389dc281395917105cf51f48bcc20c27ba51f4 -m "Added Author Details"

$git tag -a v1.1 2c389dc281395917105cf51f48bcc20c27ba51f4 -m "Added Author Details"
$
$git tag
v1.0
v1.1

Let’s push the commit v1.1 to github.

Syntax

git push origin {tagName}

$git push origin v1.1
