swift list -p 变量未设置

Question

我正在使用 swift CLI 并尝试从容器中下载多个对象。

我可以这样做

for i in `swift list container -p object/201505`; do swift download container $i; done

问题是我需要搜索和下载所有匹配的多个对象。我试过用一个小脚本来做。

#!/bin/bash

while read objects;
SAMPLE=$(swift list container objects);
do
for i in $SAMPLE; do `swift download container $i`; done
done < samples_list

但我总是收到以下问候。

Usage: swift [options] list [options] [container]
    Lists the containers for the account or the objects for a container. -p or
    --prefix is an option that will only list items beginning with that prefix.
    -d or --delimiter is option (for container listings only) that will roll up
    items with the given delimiter (see Cloud Files general documentation for
    what this means).

我的变量没有被读取吗？如何仅下载具有我设置的正确前缀的文件？

我真的不知道swift，但我想你想要

#!/bin/bash

while read objects; do
  swift list container "$objects" | while read i; do
    swift download container "$i"
  done
done < samples_list

我假设swift list 在其输出中每行写入一项。
