Method print_cmd

shell_helpers.py:117–138

Print cmd_to_string to stdout. Optionally save the command to cmd_file file, and add extra_env environment variables to the command generated. If cmd contains at least one LF, newlines are only added on LF. Otherwise, newlines are added automatically after

(self, cmd, cwd=None, cmd_file=None, extra_env=None, extra_paths=None)

                    )
