gcloud storage du

NAME: gcloud storage du - displays the amount of space in bytes used by storage resources
SYNOPSIS: gcloud storage du [URL …] [--additional-headers=HEADER=VALUE] [--all-versions, -a] [--exclude-name-pattern=EXCLUDE_NAME_PATTERN, -e EXCLUDE_NAME_PATTERN] [--exclude-name-pattern-file=EXCLUDE_NAME_PATTERN_FILE, -X EXCLUDE_NAME_PATTERN_FILE] [--readable-sizes, -r] [--summarize, -s] [--total, -c] [--zero-terminator, -0] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: Displays the amount of space in bytes used by the objects in a bucket, subdirectory, or project. This command calculates the current space usage by making a series of object listing requests, which can take a long time for large buckets. If your bucket contains hundreds of thousands of objects, or if you want to monitor your bucket size over time, use Monitoring instead, as described in Get bucket size
EXAMPLES: To list the size of each object in a bucket:
gcloud storage du gs://bucketname

To list the size of each object in the prefix subdirectory:
gcloud storage du gs://bucketname/prefix/*

To print the total number of bytes in a bucket in human-readable form:
gcloud storage du -c gs://bucketname

To see a summary of the total number of bytes in two given buckets:
gcloud storage du -s gs://bucket1 gs://bucket2

To list the size of each object in a bucket with Object Versioning enabled, including noncurrent objects:
gcloud storage 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:
gcloud storage du -e "*.bak" -0 gs://bucketname

To list the size of each bucket in a project and the total size of the project:
gcloud storage du --summarize --readable-sizes --total
POSITIONAL ARGUMENTS: [URL …]

The url of objects to list.
FLAGS: --additional-headers=HEADER=VALUE

Includes arbitrary headers in storage API calls. Accepts a comma separated list of key=value pairs, e.g. header1=value1,header2=value2. Overrides the default storage/additional_headers property value for this command invocation.

--all-versions, -a

Includes noncurrent object versions for a bucket with Object Versioning enabled. Also prints the generation and metageneration number for each listed object.

--exclude-name-pattern=EXCLUDE_NAME_PATTERN, -e EXCLUDE_NAME_PATTERN

Exclude a pattern from the report. Example: -e "*.o" excludes any object that ends in ".o". Can be specified multiple times.

--exclude-name-pattern-file=EXCLUDE_NAME_PATTERN_FILE, -X EXCLUDE_NAME_PATTERN_FILE

Similar to -e, but excludes patterns from the given file. The patterns to exclude should be listed one per line.

--readable-sizes, -r

Prints object sizes in human-readable format. For example, 1 KiB, 234 MiB, or 2GiB.

--summarize, -s

Displays only the summary for each argument.

--total, -c

Includes a total size of all input sources.

--zero-terminator, -0

Ends each output line with a 0 byte rather than a newline. You can use this to make the output machine-readable.
