该命令列举指定身份凭证下的buckets，或该身份凭证下对应endpoint的objects。默认显示长格式，
ossutil在列举buckets或者objects的同时展示它们的一些附加信息。如果指定了--short-format选
项，则显示精简格式。
--encoding-type选项
如果指定了encoding-type为url，则表示输入的object（或prefix）为经过url编码的，此时如果指定了
--marker选项或--upload-id-marker选项，ossutil默认指定的marker或upload-id-marker也同样是经过
url编码的。注意：形如oss://bucket/object的cloud_url，输入形式为：oss://bucket/url_encode(object)，
其中oss://bucket/字符串不需要编码。
--include和--exclude选项
可以指定该选项以指定规则筛选要操作的文件/object
规则支持以下格式：
*：匹配索引
?：匹配单个字符
[sequence]：匹配sequence的任意字符
[!sequence]：匹配不在sequence的任意字符
注意：规则不支持带目录的格式，e.g.，--include "/usr/*/test/*.jpg"。
--include和--exclude可以出现多次。当多个规则出现时，这些规则按从左往右的顺序应用
用法：
该命令有两种用法：
1) ossutil ls [oss://] [-s] [--limited-num num] [--marker marker]
如果用户列举时缺失cloud_url参数，则ossutil获取用户的身份凭证信息（从配置文件中读取），
并列举该身份凭证下的所有buckets，并显示每个bucket的最新更新时间，位置，存储方式等信息。
如果指定了--short-format选项则只输出bucket名称。该用法不支持--directory选项。
2) ossutil ls oss://bucket[/prefix] [-s] [-d] [-m] [-a] [--limited-num num] [--marker marker] [--upload-id-marker umarker] [--version-id-marker id_marker] [--all-versions]
如果未指定--multipart和--all-type选项，则ossutil列举指定bucket下的objects（如果指定
了前缀，则列举拥有该前缀的objects）。并同时展示object大小，最新更新时间和etag，但是如果
指定了--short-format选项则只输出object名称。如果指定了--directory选项，则返回指定bucket
下以指定前缀开头的第一层目录下的文件和子目录，但是不递归显示所有子目录，此时默认为精简
格式。所有的目录均以/结尾。
如果指定了--multipart选项，则显示指定URL(oss://bucket[/prefix])下未完成的上传任务，
即，列举未complete的Multipart Upload事件的uploadId，这些Multipart Upload事件的object名
称以指定的prefix为前缀。ossutil同时显示uploadId的init时间。该选项同样支持--short-format
和--directory选项。（Multipart同样用于cp命令中大文件的断点续传，关于Multipart的更多信息
见：https://help.aliyun.com/document_detail/31991.html?spm=5176.doc31992.6.880.VOSDk5）。
如果指定了--all-type选项，则显示指定URL(oss://bucket[/prefix])下的object和未完成的
上传任务（即，同时列举以prefix为前缀的object，和object名称以prefix为前缀的所有未complete
的uploadId）。该选项同样支持--short-format和--directory选项。
如果指定了--limited-num选项，ossutil总共会输出的对象个数不超过limited-num个，当同时
输出object和Multipart Upload时，两者的总数不超过limited-num个。
在列举objects时，--upload-id-marker选项不起作用。在列举Multipart Uploads事件时，--marker
和--upload-id-marker选项同时限定了列举的起始位置，更多信息请见oss的官网：
https://help.aliyun.com/document_detail/31997.html?spm=5176.doc31965.6.887.MK6GVw.

detailHelpText: `
The command list buckets of the specified credentials. or objects of the specified
endpoint and credentials, with simple additional information, about each matching
provider, bucket, subdirectory, or object. If --short-format option is specified,
ossutil will show by short format.
--encoding-type option
If the --encoding-type option is setted to url, the object/prefix inputted is url
encoded, if the --marker option or --upload-id-marker option is specified, ossutil
will consider the marker or upload-id-marker inputted is also url encoded.
Note: If the option is specified, the cloud_url like: oss://bucket/object should be
inputted as: oss://bucket/url_encode(object), the string: oss://bucket/ should not
be url encoded.
--include and --exclude option:
These parameters perform pattern matching to either exclude or include a particular file or object
The following pattern symbols are supported.
*: Matches everything
?: Matches any single character
[sequence]: Matches any character in sequence
[!sequence]: Matches any character not in sequence
Note: does not support patterns containing directory info. e.g., --include "/usr/*/test/*.jpg"
Any number of these parameters can be passed to a command. You can do this by providing an --exclude
or --include argument multiple times, e.g.,
--include "*.txt" --include "*.png".
When there are multi filters, the rule is the filters that appear later in the command take precedence
over filters that appear earlier in the command
Usage:
There are two usages:
1) ossutil ls [oss://] [-s] [--limited-num num] [--marker marker]
If you list without a cloud_url, ossutil lists all the buckets using the credentials
in config file with last modified time and location in addition. --show_format option
will ignore last modified time and location. The usage do not support --directory
option.
2) ossutil ls oss://bucket[/prefix] [-s] [-d] [-m] [-a] [--limited-num num] [--marker marker] [--upload-id-marker umarker] [--version-id-marker id_marker] [--all-versions]
If you list without --multipart and --all-type option, ossutil will list objects
in the specified bucket(with the prefix if you specified), with object size, last
modified time and etag in addition, --short-format option ignores all the additional
information. --directory option returns top-level subdirectory names instead of contents
of the subdirectory, which in default show by short format. the directory is end with /.
--multipart option will show multipart upload tasks under the cloud_url(oss://bucket[/prefix]),
which means, ossutil will show the uploadId of those uncompleted multipart, whose object
name starts with the specified prefix. ossutil will show the init time of uploadId meanwhile.
The usage also supports --short-format and --directory option. (Multipart upload is also used
in resume cp. More information about multipart see: https://help.aliyun.com/document_detail/31991.html?spm=5176.doc31992.6.880.VOSDk5).
--all-type option will show objects and multipart upload tasks under the cloud_url(oss://bucket[/prefix]),
which means, ossutil will both show the objects with the specified prefix and the uploadId of
those uncompleted multipart, whose object name starts with the specified prefix. The usage also
support --short-format and --directory option.
If user specified --limited-num option, the total num will not exceed the num. If user list
objects and Multipart Uploads meanwhile, the total num of objects and Multipart Uploads will not
exceed the num.
--upload-id-marker option is not effective when list objects. When list Multipart Uploads,
--marker option and --upload-id-marker option decide the initial position of listing meanwhile,
for more initial, see: https://help.aliyun.com/document_detail/31997.html?spm=5176.doc31965.6.887.MK6GVw.
