Technical guide
Create a Git branch from an earlier commit
Start a branch at an earlier commit or release tag, keep detached-HEAD work, and understand what happens when the branch later merges into main.
Explainer
Can Filebeat load multiple configuration files?
Split Filebeat inputs and modules into separate YAML files, enable live reloading, and keep output settings in the main configuration.
Technical guide
Can Git serve as a backup tool?
Use Git remotes, mirrors, and bundles to preserve committed history, while accounting for uncommitted files, LFS objects, repository metadata, and restore tests.
Technical guide
Recover a deleted Git branch
Find a surviving branch tip in local refs, the reflog, or remaining objects, then recreate the branch. Recovery depends on object availability, not a fixed deadline.
Technical guide
Commit only part of a file in Git
Use git add --patch to stage selected changes, inspect the complete staged snapshot, and commit it without accidentally including the rest of the file.
Technical guide
Compare two Git branches
Choose endpoint diffs, merge-base diffs, or commit ranges to compare Git branches, then generate and check a patch when you need to transfer file changes.
Technical guide
Create a Git tag and publish it on GitHub
Create and push a specific Git tag, distinguish annotated tags from signatures and releases, and handle an incorrect release marker.
Technical guide
Create a Git branch from another branch
Choose a local or remote-tracking branch as a starting point, control upstream tracking, and understand how the new branch diverges.
Technical guide
Export uncommitted Git changes as a patch
Export staged, unstaged, new, and binary files as a Git patch; check application, handle conflicts, and preserve commits with format-patch.
Technical guide
What is the difference between git add -A and git add .?
In modern Git, both stage additions, modifications, and deletions. Their path scope differs when you run them from a subdirectory.
Technical guide
Fetch and check out a specific Git tag
Fetch a Git tag, make a shallow clone or source archive, preserve detached commits, and verify the revision used for deployment.
Technical guide
Clone a Git repository with its submodules
Clone nested Git submodules, check out recorded commits, deliberately update dependencies, and configure private-repository access in CI.
