While the cat command does not compute a checksum, it is otherwise equivalent to doing: $ {parent_command} cp url... - (The final '-' causes gcloud to stream the output to stdout.) a The following command writes all text files in a bucket to stdout: $ {command} gs://bucket/*.txt The following command outputs a short header describing file.txt, along with its contents: $ {command} -d gs://my-bucket/file.txt The following command outputs bytes 256-939 of file.txt: $ {command} -r 256-939 gs://my-bucket/file.txt The following command outputs the last 5 bytes of file.txt: $ {command} -r -5 gs://my-bucket/file.txt ) DESCRIPTIONEXAMPLESc|jddd|jdddd |jd d ttjd  t j |t j |dy)Nurl+zThe url of objects to list.)nargshelpz-dz --display-url store_truez%Prints the header before each object.)actionr(z-rz--rangea 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)typer(T)command_only_reads_data) add_argumentrtextwrapdedentr add_additional_headers_flagadd_encryption_flags)parsers rArgszCat.Args^s S/LM   4 6     __ ' ( )& %%f- vtDrc tj||jrg}|jD]p}tj|}t |tj s.tjdj|j|j|rtj|jtjj tj"j$}t'j(||j*t-|j.ddt-|j.dd}t1j2||_y)Nz@cat only works for valid cloud URLs. {} is an invalid cloud URL.) fields_scoperecursion_requestedrrr) start_byteend_byte) task_iterator)r initialize_key_storer%r storage_url_from_string isinstanceCloudUrlr InvalidUrlErrorformat url_stringappendr NameExpansionIteratorr FieldsScopeNO_ACLRecursionSettingNOrget_cat_task_iterator display_urlgetattrranger execute_tasks exit_code)selfargs storage_urlsr@ url_objectsource_expansion_iteratorr9s rRunzCat.Run|s((. xxl* 88D *k&:&:;&&(FFLf+5+@+@GBC C J' !!/ D D **11*;;>>!@ &;;! 4::w2UD1 3M #00}MDNrN)__name__ __module__ __qualname____doc__ detailed_help staticmethodr3rRrrr!r!8s3;   -DEE:Nrr!)rV __future__rrrr.googlecloudsdk.api_lib.storagergooglecloudsdk.callioperr"googlecloudsdk.command_lib.storager r r r r (googlecloudsdk.command_lib.storage.tasksr,googlecloudsdk.command_lib.storage.tasks.catrrUniverseCompatibleCommandr!rYrrrbseK&'4/(>54=:BJ/*]N$,,]N]Nr
