[sudhir.tataraju.WBLL0717E4418] ? cat test.sh

#!bin/bash

i=2

value2=abc

echo "`$value$i`"

输出:

[sudhir.tataraju.WBLL0717E4418] ? sh test.sh
test.sh: line 8: 2: command not found

调试输出:

[sudhir.tataraju.WBLL0717E4418] ? sh -x test.sh
+ i=2
+ value2=abc
++ 2
test.sh: line 8: 2: command not found
+ echo ''

如何获得输出abc没有错误？

我现在使用 GetMedia API 通过 AWS Connect 服务将数据提取到（Kinesis Video Stream）KVS，我能够提取有效负载，但如何将此输出转换为 mp3/wav？我想将此输出提取到 AWS Transcribe 服务，以获取由 AWS Connect 服务提取到 KVS 的音频呼叫的文本格式。

以下代码的有效负载输出如下：

00#AWS_KINESISVIDEO_CONTINUATION_TOKEND\x87....\x1faudio/L16;rate=8000;channels=1;\x12T\xc......00"AWS_KINESISVIDEO_MILLIS_BEHIND_NOWD\x87\x10\x00\x00\x074564302g\xc8\x10\ x00\x00^E\xa3\x10\x00\x00#AWS_KINESISVIDEO_CONTINUATION_TOKEND\x87\x10\x00\x00/91343852333181432506572546233025969374566791063'

注：上面的回复太长，所以粘贴了一些。

import json
import boto3

kinesis_client = boto3.client('kinesisvideo', region_name='us-east-1')

response = kinesis_client.get_data_endpoint(
    StreamARN='arn:aws:kinesisvideo:us-east-1:47...,
    APIName='GET_MEDIA')

t = response['DataEndpoint']
video_client = boto3.client('kinesis-video-media', endpoint_url=t, region_name='us-east-1')
stream = video_client.get_media(
    StreamARN='arn:aws:kinesisvideo:us-east-1:47...',
    StartSelector={'StartSelectorType': 'EARLIEST'})

streamingBody = stream['Payload']
print(streamingBody.read())

请建议我如何将有效负载输出转换为 mp3/wav 等。

我正在尝试更新正在运行的Docker容器的网络。

注意：运行容器时，我没有连接任何网络。

为什么baseline.config.total.no.1of.banner=a_1和baseline.config.total.no.2of.banner=b_2包含在输出？不应该baseline.config.total.no..*.在1of和之间需要一个点2of？

$ grep "baseline.config.total.no..*." ./output/messages_en.properties
baseline.config.total.no.1of.banner=a_1
baseline.config.total.no.2of.banner=b_2
baseline.config.total.no.1.of.banner=10-1streak
