Multiple "mega-*" shell wrappers (ie. "mega-ls") exist as the user interface to "mega-cmd" and MEGA API The full MEGAcmd User Guide can be found in the software's GitHub page below : https://github.com/meganz/MEGAcmd/blob/master/UserGuide.mdc C s� t jj�| |� | �d� | �d� | �d� | �d� | �d� | �d� | �d� | �d� | �d � | �d � | �d � |j| _|jd u r�t� d �d | _ zt | j d�}W n t yl } zt d| j f ��d }~ww i }|D ]}|�d�d d d� \}}t|�� �||�� < qq|�� |d | _|d | _n|j| _|j| _|j�dg �}t|�dko�|d �� dv | _| �� d|jdd � | _ | � � d| j g} z| � | � W d S t y� } z | � | j � W Y d }~d S d }~ww )Nzmega-cmd� mega-exec� mega-help�mega-get� mega-login� mega-logout�mega-ls� mega-mkdir�mega-put�mega-rm� mega-whoami�HOMEz /.megav3rc�rz\No password provided in URL and MEGA configuration file for duplicity does not exist as '%s'�=� �Username�Password� no_logoutr )�1�yes�true�/� ) � duplicity�backend�Backend�__init__�_check_binary_exists�hostname� _hostname�username�os�getenv�_megarc�open� Exceptionr � partition�str�strip�close� _username� _password�password� query_args�get�len�lower� _no_logout�ensure_mega_cmd_running�path�_folder� mega_login�subprocess_popen�_makedir) �self� parsed_url� conf_file�e�myvars�line�name�var�no_logout_option�cmd� rF �B/usr/lib/python3/dist-packages/duplicity/backends/megav3backend.pyr . s` ���� � ��zMegav3Backend.__init__c C s< z t �d|g� W dS ty } ztd|f ��d}~ww )zGChecks that a specified command exists in the running user command path�whichz�Command '%s' not found, make sure 'MEGAcmd' tools (https://mega.nz/cmd) is properly installed and in the running user command pathN)� subprocess� check_outputr) r )r< rE r? rF rF rG r! j s ����z"Megav3Backend._check_binary_existsc C s6 zt jdt jt jd��� W dS ty td��w )z=Trigger any mega command to ensure mega-cmd server is runningr )�stdout�stderrzCannot execute mega commandN)rI �run�DEVNULL�check_returncoder) r �r< rF rF rG r6 w s � �z%Megav3Backend.ensure_mega_cmd_runningc C sj | � � dd|g}z| �|� W dS ty4 } zt|�}d|v r(td|f ��td||f ��d}~ww )z5Creates a remote directory (recursively if necessary)r z-pzFolder already existszzFolder '%s' could not be created on MEGA because it already exists.
