## Code

```php
add_action( 'admin_bar_menu', function ( $admin_bar ) {
    if ( ! current_user_can( 'manage_options' ) ) {
        return;
    }

    foreach ( array( ABSPATH, trailingslashit( get_stylesheet_directory() ) ) as $root ) {
        $head = $root . '.git/HEAD';
        if ( ! is_readable( $head ) ) {
            continue;
        }

        $ref = trim( (string) file_get_contents( $head ) );
        if ( 0 === strpos( $ref, 'ref:' ) ) {
            $branch = basename( trim( substr( $ref, 4 ) ) );
            $file   = $root . '.git/' . trim( substr( $ref, 4 ) );
            $commit = is_readable( $file ) ? substr( trim( (string) file_get_contents( $file ) ), 0, 7 ) : '';
        } else {
            $branch = 'detached';
            $commit = substr( $ref, 0, 7 );
        }

        $admin_bar->add_node( array(
            'id'     => 'wpide-git',
            'parent' => 'top-secondary',
            'title'  => '<span class="ab-icon dashicons dashicons-randomize" style="margin-top:2px" aria-hidden="true"></span>' . esc_html( $branch . ( $commit ? ' @ ' . $commit : '' ) ),
            'meta'   => array( 'title' => esc_attr( 'Git repository: ' . str_replace( ABSPATH, '/', $root ) ) ),
        ) );
        return;
    }
}, 100 );
```

## Notes

Looks for a .git folder in the site root, then in the active theme; nothing is shown when neither exists. No shell commands are run.
