NAME
|
|
gcloud storage cat - outputs the contents of one or more URLs to stdout
|
|
|
|
SYNOPSIS
|
|
gcloud storage cat URL [URL ...] [--additional-headers=HEADER=VALUE]
|
|
[--display-url, -d] [--range=RANGE, -r RANGE]
|
|
[--decryption-keys=[DECRYPTION_KEY,...]] [GCLOUD_WIDE_FLAG ...]
|
|
|
|
DESCRIPTION
|
|
The cat command outputs the contents of one or more URLs to stdout. While
|
|
the cat command does not compute a checksum, it is otherwise equivalent to
|
|
doing:
|
|
|
|
$ gcloud storage cp url... -
|
|
|
|
(The final '-' causes gcloud to stream the output to stdout.)
|
|
|
|
EXAMPLES
|
|
The following command writes all text files in a bucket to stdout:
|
|
|
|
$ gcloud storage cat gs://bucket/*.txt
|
|
|
|
The following command outputs a short header describing file.txt, along
|
|
with its contents:
|
|
|
|
$ gcloud storage cat -d gs://my-bucket/file.txt
|
|
|
|
The following command outputs bytes 256-939 of file.txt:
|
|
|
|
$ gcloud storage cat -r 256-939 gs://my-bucket/file.txt
|
|
|
|
The following command outputs the last 5 bytes of file.txt:
|
|
|
|
$ gcloud storage cat -r -5 gs://my-bucket/file.txt
|
|
|
|
POSITIONAL ARGUMENTS
|
|
URL [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.
|
|
|
|
--display-url, -d
|
|
Prints the header before each object.
|
|
|
|
--range=RANGE, -r RANGE
|
|
Causes gcloud storage to output just the specified byte range of the
|
|
object. In a case where "start" = 'x', and "end" = 'y', ranges take the
|
|
form: x-y (e.g., -r 256-5939), x- (e.g., -r 256-), -y (e.g., -r -5)
|
|
|
|
When offsets start at 0, x-y means to return bytes x through y
|
|
(inclusive), x- means to return bytes x through the end of the object,
|
|
and -y changes the role of y. If -y is present, then it returns the
|
|
last y bytes of the object.
|
|
|
|
If the bytes are out of range of the object, then nothing is printed
|
|
|
|
ENCRYPTION FLAGS
|
|
--decryption-keys=[DECRYPTION_KEY,...]
|
|
A comma-separated list of customer-supplied encryption keys (RFC 4648
|
|
section 4 base64-encoded AES256 strings) that will be used to decrypt
|
|
Google Cloud Storage objects. Data encrypted with a customer-managed
|
|
encryption key (CMEK) is decrypted automatically, so CMEKs do not need
|
|
to be listed here.
|
|
|
|
GCLOUD WIDE FLAGS
|
|
These flags are available to all commands: --access-token-file, --account,
|
|
--billing-project, --configuration, --flags-file, --flatten, --format,
|
|
--help, --impersonate-service-account, --log-http, --project, --quiet,
|
|
--trace-token, --user-output-enabled, --verbosity.
|
|
|
|
Run $ gcloud help for details.
