# Git

## Fetch a remote branch

- Create a local branch that tracks a remote branch

```shell
git checkout --track origin/develop
```

If you want to change the name of the local branch (_NOT A GOOD IDEA_)

```shell
git checkout --track -b gniagnia origin/develop
```

## Amend without editing commit message

```shell
git commit --amend --no-edit
```

## Copy current HEAD sha sum to clipboard

```shell
git rev-parse HEAD | xclip
```

## Conditional Git configuration

Since git 2.13, there is an option to include configuration (or not) based on a condition

Here is an example use case

```txt
# Specific configurations for work and personnal repos
[includeIf "gitdir:~/code/work/"]
    path = .gitconfig.work
[includeIf "gitdir:~/code/oss/"]
    path = .gitconfig.oss
```

If include, settings in any configuration found file provided by the path
parameter will by append to or will overide current configuration.

## Switch to previous branch

```sh
git checkout -
```
