Label the current commit with a tag.

Git: Label the current commit with a tag inside the disposable repository created by the input setup.

git tag lesson-1
git tag --list

Expected output EXAMPLE

lesson-1

Details

Requires Git and Bash. Run in a disposable practice repository. The test setup below creates the starting files and commits.

Keep in mind

Use a disposable practice directory. The setup configures a synthetic author locally for this repository only; it does not change global Git settings.

✓ Verified

Tested on Ubuntu 24.04.5 LTS · 2026-11-02 18:29:44 UTC · git version 2.43.0 · bash 5.2.21-2ubuntu4; coreutils 9.4-3ubuntu6.3

Test inputs, results and environment

The exact published code ran in a dedicated Linux test container with prepared inputs. Snippet process uid 65534 with a read-only root filesystem and temporary working files. Networking disabled. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.

Architecture / host kernel: x86_64 / 6.18.54.1-microsoft-standard-WSL2
Snippet identity / locale: uid=65534, gid=65534 (unprivileged process) / C.UTF-8
Interpreter invocation: bash -euo pipefail -c <published code>
Container image ID: sha256:ec91410a8f6ec3e985830b5e3a0560306d36f8c1c5ccd91a6699abe707123fa3

Test input setup

These are the prepared inputs used by the test harness. See Details above for the prerequisites and how to run this example.

git init -q -b main
git config user.name 'Practice User'
git config user.email 'learner@example.invalid'
git config commit.gpgsign false
printf 'first\n' > lesson.txt
git add lesson.txt
git commit -qm 'First lesson'
