gcloudstoragecatgs://bucket/*.txt

The following command outputs a short header describing file.txt, along with itscontents:

gcloudstoragecat-dgs://my-bucket/file.txt

The following command outputs bytes 256-939 of file.txt:

gcloudstoragecat-r256-939gs://my-bucket/file.txt

The following command outputs the last 5 bytes of file.txt:

gcloudstoragecat-r-5gs://my-bucket/file.txt

URL [URL …]

The url of objects to list.

--additional-headers=HEADER=VALUE

Includes arbitrary headers in storage API calls. Accepts a comma separated listof key=value pairs, e.g.header1=value1,header2=value2. Overridesthe defaultstorage/additional_headers property value for thiscommand invocation.

--display-url,-d

Prints the header before each object.

--range=RANGE,-rRANGE

Causes gcloud storage to output just the specified byte range of the object. Ina 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 roleof 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

--decryption-keys=[DECRYPTION_KEY,…]

A comma-separated list of customer-supplied encryption keys (RFC 4648 section 4base64-encoded AES256 strings) that will be used to decrypt Cloud Storageobjects. Data encrypted with a customer-managed encryption key (CMEK) isdecrypted automatically, so CMEKs do not need to be listed here.
