""" _DETAILED_HELP_TEXT = (""" <B>SYNOPSIS</B> """ + _SYNOPSIS + """ <B>DESCRIPTION</B> The du command displays the amount of space in bytes used up by the objects in a bucket, subdirectory, or project. The syntax emulates the Linux ``du -b`` command, which reports the disk usage of files and subdirectories. For example, the following command reports the total space used by all objects and subdirectories under gs://your-bucket/dir: gsutil du -s -a gs://your-bucket/dir <B>OPTIONS</B> -0 Ends each output line with a 0 byte rather than a newline. You can use this to make the output machine-readable. -a Includes both live and noncurrent object versions. Also prints the generation and metageneration number for each listed object. If this flag is not specified, only live object versions are included. -c Includes a total size at the end of the output. -e Exclude a pattern from the report. Example: -e ".o" excludes any object that ends in ".o". Can be specified multiple times. -h Prints object sizes in human-readable format. For example, ``1 KiB``, ``234 MiB``, or ``2GiB``. -s Displays only the total size for each argument, omitting the list of individual objects. -X Similar to ``-e``, but excludes patterns from the given file. The patterns to exclude should be listed one per line. <B>EXAMPLES</B> To list the size of each object in a bucket: gsutil du gs://bucketname To list the size of each object in the ``prefix`` subdirectory: gsutil du gs://bucketname/prefix/ To include the total number of bytes in human-readable form: gsutil du -ch gs://bucketname To see only the summary of the total number of (live) bytes in two given buckets: gsutil du -s gs://bucket1 gs://bucket2 To list the size of each object in a bucket with `Object Versioning <https://cloud.google.com/storage/docs/object-versioning>`_ enabled, including noncurrent objects: gsutil du -a gs://bucketname To list the size of each object in a bucket, except objects that end in ".bak", with each object printed ending in a null byte: gsutil du -e ".bak" -0 gs://bucketname To list the size of each bucket in a project and the total size of the project: gsutil -o GSUtil:default_project_id=project-name du -shc """) class DuCommand(Command): """Implementation of gsutil du command.""" # Command specification.
