我有一个centos码头工人映像，我试图在容器内运行杜比数字工具“ spectrum_avg”进行分析。如果我通过以下命令登录docker容器，则执行命令可用。
docker container -exec -ti <id> /bin/bash
[test@container ~]$ spectrum_avg
Spectrum Average Tool
(C) Copyright 2011 Dolby Laboratories.
Version 2.6.2
Usage: spectrum_avg [OPTION]... WAVEFILE
-c<chan>, selects channel in multichannel file
0 = first channel
-ca for all channels
-g, create on-screen graph
-go<name>, create a graph file (.png,.pdf,.jpg)
-m<map>, selects channel map for input WAVEFILE
1: L R l r C s
2: L C R l r s
3: L l C r R s
4: L R C s l r
5: L C r R l s
6: C L R l r s
no default
-s, turn off stripping lead silence
-t, send text output to standard output (default)
-to<name>, create a text file
-xmin<lim> selects minimum x-axis limit
-xmax<lim> selects maximum x-axis limit
-ymin<lim> selects minimum y-axis limit
-ymax<lim> selects maximum y-axis limit
发出以下命令时，尽管该命令就在其中，但我找不到该命令。
[test@host Scripts]$ docker container exec container_1 bash -c "cd /opt/SATS ; ls ; spectrum_avg"
