NAME
    gcloud storage objects compose - concatenate a sequence of objects into a
        new composite object

SYNOPSIS
    gcloud storage objects compose SOURCE [SOURCE ...] DESTINATION
        [--additional-headers=HEADER=VALUE]
        [--if-generation-match=GENERATION
          --if-metageneration-match=METAGENERATION] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    gcloud storage objects compose creates a new object whose content is the
    concatenation of a given sequence of source objects in the same bucket. For
    more information, please see: composite objects documentation
    (https://cloud.google.com/storage/docs/composite-objects).

    There is a limit (currently 32) to the number of components that can be
    composed in a single operation.

EXAMPLES
    The following command creates a new object target.txt by concatenating
    a.txt and b.txt:

        $ gcloud storage objects compose gs://bucket/a.txt \
            gs://bucket/b.txt gs://bucket/target.txt

POSITIONAL ARGUMENTS
     SOURCE [SOURCE ...]
        The list of source objects that will be concatenated into a single
        object.

     DESTINATION
        The destination object.

FLAGS
     --additional-headers=HEADER=VALUE

        this command invocation.

        Execute only if the metageneration matches the metageneration of the
        requested object.
