.sh_in_dir(dir, *shell_commands) ⇒ Object

Executes a string or an array of strings in a shell in the given directory. NOTE: this does NOT unbundle. The caller's Bundler environment (BUNDLE_GEMFILE, RUBYOPT, ...) is inherited, so a bundle command run here against a different directory's Gemfile still resolves the caller's Gemfile. Wrap the call in Bundler.with_unbundled_env when that matters.
