## Usage

The simplest form is to `cd` to a directory containing all the repos you want to operate on, then write your Git command changing `git` to `gitall`.
To pass options to the Git command, you must add `--` before your command to tell gitall to stop parsing its own options and pass them to Git.
For example, to list all remote and local repository branches you need to run `gitall -- branch -va`.

**Pro Tip:** if you add a file called `git-foo` to your `PATH` (either via copying or symlinking), you can call that program _through_ `git` using `git foo`; no additional aliases or setup needed.
So, after running `ln -s /usr/bin/gitall /usr/bin/git-all`, you can use gitall via `git all` exactly the same as if you used `gitall`.

```console
$ git clone https://github.com/mattmahn/gitall.rs && cd gitall.rs
$ cargo build --release
# install target/release/gitall /usr/bin/
```

Shell completions for Bash, Zsh, fish, Elvish, and PowerShell are also generated during build; you can find them at `target/release/build/gitall-<hash>/out/`.
Refer to your shell's documentation for installation.
