- 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 defaultstorage/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 Cloud Storage objects. Data encrypted with a customer-managed encryption key (CMEK) is decrypted automatically, so CMEKs do not need to be listed here.
