When using the Cloud SDK, use ``gcloud components update``. The gsutil update command downloads the latest gsutil release, checks its version, and offers to let you update to it if it differs from the version you're currently running. Once you say "Y" to the prompt of whether to install the update, the gsutil update command locates where the running copy of gsutil is installed, unpacks the new version into an adjacent directory, moves the previous version aside, moves the new version to where the previous version was installed, and removes the moved-aside old version. Because of this, users are cautioned not to store data in the gsutil directory, since that data will be lost when you update gsutil. (Some users change directories into the gsutil directory to run the command. We advise against doing that, for this reason.) Note also that the gsutil update command will refuse to run if it finds user data in the gsutil directory. By default gsutil update will retrieve the new code from %s, but you can optionally specify a URL to use instead. This is primarily used for distributing pre-release versions of the code to a small group of early test users. NOTE: gsutil periodically checks whether a more recent software update is available. By default this check is performed every 30 days; you can change (or disable) this check by editing the software_update_check_period variable in the .boto config file. Note also that gsutil will only check for software updates if stdin, stdout, and stderr are all connected to a TTY, to avoid interfering with cron jobs, streaming transfers, and other cases where gsutil input or output are redirected from/to files or pipes. Software update periodic checks are also disabled by the gsutil -q option (see 'gsutil help options') <B>OPTIONS</B> -f Forces the update command to offer to let you update, even if you have the most current copy already. This can be useful if you have a corrupted local copy. -n Causes update command to run without prompting [Y/n] whether to continue if an update is available. c @ s� e Zd ZdZejddgeddddddejej gej d � Z ej ddgd d e i d �Z d d� Zg d�Zdd� Zdd� Zdd� Zdd� ZdS )� UpdateCommandz(Implementation of gsutil update command.�update�refreshr � �fnTF) �command_name_aliases�usage_synopsis�min_args�max_args�supported_sub_args� file_url_ok�provider_url_ok�urls_start_arg�gs_api_support�gs_default_api� command_helpz#Update to the latest gsutil release)� help_name�help_name_aliases� help_type�help_one_line_summary� help_text�subcommand_help_textc C s� t js t jrdS t�� }t�tj�j|kr.dS t � }d� |�}| � |||� g }|D ]0}t t� t�|�tj ��} |�d| |f � qTtd� t�d��d||| jd� |�f dd��dS ) a� Explains what to do if sudo needed to update gsutil software. Happens if gsutil was previously installed by a different user (typically if someone originally installed in a shared file system location, using sudo). Args: tf: Opened TarFile. dirs_to_remove: List of directories to remove. old_cwd: Path to the working directory we should chdir back to if sudo is needed. It's possible that we've chdir'd to a temp directory that's been deleted, which can cause odd behavior (e.g. OSErrors when opening the metrics subprocess). If this is not truthy, we won't attempt to chdir back to this value. Raises: CommandException: if errors encountered. N� z sudo chmod %s %s� a Since it was installed by a different user previously, you will need to update using the following commands.

This provides a fail-safe check to ensure we don't try to overwrite or delete any important directories.
