Git Aliases

---

---

Git aliases are user defined abbreviations we define for frequently used Git commands. Aliases allow us to create short, custom commands that map to more complex Git commands, making the development process more efficient and personalized.

Aliases are stored in our Git configuration file, and once set, they are available for use across all repositories on the machine.

For example, instead of typing a full command (such as git status or git log --oneline), we can create a shorter alias (such as `git st` or `git lg`) to perform the same task.

Why Use Git Aliases?

There are several benefits to using Git aliases:

• Speed and Efficiency: Aliases reduce the time spent typing long or complex commands.

• Customization: We can create shortcuts for commands that we use often or combine multiple commands into a single alias.

• Consistency Across Projects: Once aliases are set up, they are globally available in our Git configuration, ensuring consistency across all the projects.

• Reducing Errors: By using aliases, we minimize the risk of mistyping complex commands.

Alias Creation

Creating a Git alias is simple and can be done using the `git config` command.

git config --global alias.<alias-name> '<git-command>'

For example, let's create an alias for git status, as follows:

git config --global alias.st 'status'

Now, every time we type `git st`, Git will interpret it as `git status`. The --global flag ensures that the alias is available for all repositories on the machine. To create an alias only for a specific repository, we can omit the `--global flag.

To view configured aliases, open the Git configuration file:

git config --global -e

Useful Git Aliases

Following are some commonly used Git aliases that can speed up the development workflow:

Alias for Git Status

Instead of typing `git status` all the time, we can create a simple alias like:

git config --global alias.st 'status'

Now, `git st` will show the status of our repository, saving us a few keystrokes.

Alias for Git Log

The `git log` command is powerful but can be overwhelming due to the amount of information it shows. We can simplify the output using the `--oneline` and `--graph` options to create a more readable log:

git config --global alias.lg 'log --oneline --graph --decorate --all'

With this alias, running `git lg` will give a clean, one-line-per-commit history with a visual representation of the branch structure.

Alias for Git Checkout

We can create an alias to speed up the commit process, particularly for committing with a message

git config --global alias.ci 'commit'
git config --global alias.cm 'commit -m'

With this setup, `git ci` will trigger a commit, and git cm message` will commit with the specified message in one command.

Alias for Git Diff

The `git diff` command shows changes between commits, branches, or the working directory. A useful alias for quickly viewing changes is:

git config --global alias.d 'diff'

`git d` will display the differences between the working directory and the latest commit.

Alias for Git Add

To save time when staging files, we can create an alias for the git add command:

git config --global alias.a 'add'

`git a <file>` will add all files in the working directory to the staging area.
