This is my general starter .gitignore file for projects. I have a separate .gitignore for WordPress websites.
By using “git add -p”, I can include some of my current changes in my commit (without including all of my changes).
While my mental model visualizes a Git branch as a stack of building blocks, in actuality a Git branch is a pointer to a single commit. Under the hood Git stores a text file for each branch and in the text file is a single line, which is the commit hash indicating the commit at the tip of that branch.
I’m a big fan of Git and I’ve worked with lost of developers in growing their Git skills. Often developers learning Git, start by learning how to write a “good” commit message. While writing “good” commit messages is an important skill, in my opinion it is the wrong place to start.
These are the rules I follow when writing Git commit messages. I’ve found these serve me well and are compatible with most projects I work on (if a project has a specific set of rules for writing Git commit messages, those would override any rules I’ve outlined here).
When performing a Git rebase, I often find myself in the situation where I have one or more merge conflicts. This is how I resolve these merge conflicts.
We can’t do a fast-forward merge when the most recent commit on the receiving branch does not appear in the branch we are merging in. One of our options in this situation is to rebase the branch we want to merge in.
When visualizing Git branches, I find it easier to think of them as stacks of building blocks rather than the traditional Directed Acyclic Graph (DAG) visualizations.
When you are using Git commit validation (a.k.a. commit linting) and it fails, it is frustrating to re-type your message. Git stores the commit message that failed validation. You can use this stored message to start your new commit message.
When working with Git and you run “git pull” sometimes you get the error message, “There is no tracking information for the current branch.” You can fix this by running a command to set your local branch to track the origin branch of the same name.
