NAME
    gcloud beta runtime-config configs variables watch - wait for a variable
        resources to change

SYNOPSIS
    gcloud beta runtime-config configs variables watch NAME
        --config-name=CONFIG_NAME [--max-wait=MAX_WAIT]
        [--newer-than=NEWER_THAN] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (BETA) This command waits for the variable resource with the specified name
    to either have its value changed or be deleted.

EXAMPLES
    To wait for a variable to change or be deleted, run:

        $ gcloud beta runtime-config configs variables watch my-var \
            --config-name=my-config

    This command will return after the variable changes, is deleted, or a
    server-defined timeout elapses.

    To wait for user-specified period of 20 seconds, run:

        $ gcloud beta runtime-config configs variables watch my-var \
            --config-name=my-config --max-wait=20

    If a watch command returns due to a timeout, the command's exit value will
    be 2. All other errors result in an exit value of 1. If the watched
    variable changes prior to the timeout, the command will exit successfully
    with a value of 0.

    Optionally, a --newer-than parameter can be specified to wait only if the
    variable hasn't changed since the specified time. If the variable has
    changed since the time passed to --newer-than, the command returns without
    waiting. For example:

        $ gcloud beta runtime-config configs variables watch my-var \
            --config-name=my-config --newer-than="2016-04-05T12:00:00Z"
